Toshiba Releases 650V 3rd Generation SiC MOSFETs in DFN8x8 Package
Article content
KAWASAKI, Japan — Toshiba Electronic Devices & Storage Corporation ('Toshiba') has launched four 650V silicon carbide (SiC) MOSFETs, equipped with its latest [1] 3rd generation SiC MOSFET chips and housed in a compact DFN8x8 package, suitable for industrial equipment, such as switched-mode power supplies and power conditioners for photovoltaic generators. Volume shipments of the four devices, ' TW031V65C,' ' TW054V65C,' ' TW092V65C,' and ' TW123V65C,' start today.
Article content
The new products are the first 3rd generation SiC MOSFETs to use the small surface-mount DFN8x8 package, which reduces volume by more than 90% compared to lead-inserted packages, such as TO-247 and TO-247-4L(X) and improves equipment power density. Surface mounting also allows use of parasitic impedance [2] components smaller than those of lead-inserted packages, reducing switching losses. DFN8x8 is a 4-pin [3] package, allowing use of a Kelvin connection of its signal source terminal for the gate drive. This reduces the influence of inductance in the source wire within the package, achieving high-speed switching performance; in the case of TW054V65C, it reduces turn-on loss by approximately 55% and turn-off loss by approximately 25% [4] compared to current Toshiba products [5], helping to reduce power loss in equipment.

Toshiba will continue to expand its lineup to contribute to improved equipment efficiency and increased power capacity.

The quantum cryptography market is expected to be valued at USD 1,157.0 million in 2024 and is anticipated to grow to USD 7,594.0 million by 2030, with a CAGR of 36.8% during the forecast period. This growth is primarily driven by rising cybersecurity threats and rapid advancements in quantum computing, which are rendering traditional encryption methods obsolete. The increasing demand for robust authentication and encryption solutions resistant to quantum hacking has fueled adoption across sectors such as finance and healthcare. Additionally, government funding and initiatives supporting quantum technology development further contribute to market expansion. However, organizations face challenges due to accelerating digitalization, stricter data privacy regulations, and potential disruptions from corporate decisions. Download PDF Brochure@ The growth in the quantum cryptography market is being fueled by increased cyberattacks, advancement in quantum computing, and major initiatives by governments around the world across various sectors as healthcare, defense, telecom, IT, finance, and education. The increase in demand for advanced security measures to protect sensitive information from malicious attacks has brought a shift from traditional cryptographic methods to more robust solutions. More especially, the digital banking and electronic transaction are increasing, and therefore, the communication system should be assuredly secured. Quantum cryptography solutions such as Quantum Key Distribution (QKD), Quantum Random Number Generators (QRNG), or hardware security modules may provide theoretically unbreakable encryption to safeguard the data and communications against increasingly sophisticated cyber threats. Based on the Organization Size, the Large Enterprises segment accounts for the highest market size during the forecast period. Quantum cryptography is mostly driven by the large enterprises segment, since managing big amounts of sensitive data requires a high level of security and there are more strict regulations in end-users like finance and healthcare. The quantum threats are very likely to stimulate significant investments into solutions resilient to such threats. Consequently, it is the large enterprises which have the potential for holistic R&D, such as that of IBM or Google, who have already been developing post-quantum cryptographic algorithms. Additional strategic partnerships with organizations, such as NIST, contribute to increased adoption. Innovators, like Cloudflare, which has already integrated post-quantum protocols, are a show of proactive action. By Vertical, Healthcare segment will grow at the highest CAGR during the forecast period. Emerging security threats, the increased need for regulatory compliances, and an ongoing process of digital transformation is driving the healthcare industry in the quantum cryptography market.

Stricter regulation like the GDPR makes organizations more and more in need of safe defense mechanisms for personal data. Moreover, the presence of leading research institutions and early adoption of quantum technologies by countries such as Germany and UK further contribute to the growth of this market. Request Sample Pages@ Unique Features in the Quantum Cryptography Market Quantum cryptography leverages Quantum Key Distribution (QKD), which ensures secure communication by using quantum principles such as superposition and entanglement. Unlike traditional encryption methods, QKD offers theoretically unbreakable security, as any attempt to intercept the key alters its quantum state, immediately alerting the sender and receiver. As quantum computers advance, they pose a significant threat to conventional encryption algorithms such as RSA and ECC. Quantum cryptography provides a future-proof solution by enabling encryption methods that cannot be cracked, even by powerful quantum computers. This ensures long-term data security in industries handling sensitive information, such as finance, healthcare, and defense. One of the distinguishing features of quantum cryptography is its ability to detect eavesdropping in real-time. Any unauthorized attempt to intercept or measure quantum-encoded information disrupts the system, alerting the users immediately. This proactive security measure strengthens data protection against cyber threats. Governments and major industries are increasingly investing in quantum cryptography to safeguard national security and critical infrastructure. Many countries are funding research initiatives, forming strategic partnerships, and setting up quantum communication networks to ensure secure data transmission. Major Highlights of the Quantum Cryptography Market With the rise in cyberattacks and data breaches, traditional encryption methods are becoming vulnerable. Quantum cryptography offers a next-generation security solution, ensuring impenetrable encryption, particularly for sectors handling sensitive data, such as finance, healthcare, and defense. Governments worldwide are heavily investing in quantum research, launching initiatives to develop quantum-secure communication networks. Countries such as the U.S., China, and those in the EU are funding quantum technology projects to safeguard critical infrastructure and national security. A key highlight of the market is the seamless integration of quantum cryptography with classical encryption systems. Hybrid models allow organizations to gradually implement quantum-secure encryption without overhauling their entire IT infrastructure, making adoption more feasible. QKD, a core technology in quantum cryptography, is being deployed in various sectors to enable ultra-secure data transmission. Several telecom providers and research institutions are testing QKD-based communication networks to enhance security for financial transactions, military operations, and government communications.
