650V silicon carbide Schottky diode for power applications

Nexperia introduces a 650V Silicon Carbide (SiC) Schottky diode designed for power applications which require ultra-high performance, low loss, and high efficiency. The 10A, 650V SiC Schottky diode is an industrial-grade part that addresses the challenges of demanding high voltage and high current applications. 

These include switched-mode power supplies, AC-DC and DC-DC converters, battery-charging infrastructure, uninterruptible power supplies and photovoltaic inverters and allow for more sustainable operations. Data centres, for example, equipped with power supplies designed using Nexperia’s PSC1065K SiC Schottky diode will be better placed to meet rigorous energy efficiency standards than those using solely silicon-based solutions.

The PSC1065K delivers leading-edge performance with temperature-independent capacitive switching and zero recovery behaviour culminating in an outstanding figure-of-merit (QC x VF). Its excellent switching performance is almost entirely independent of current and switching speed variations. 

The merged PiN Schottky (MPS) structure of the PSC1065K provides additional benefits, such as outstanding robustness against surge currents that eliminate the need for additional protection circuitry. These features significantly reduce system complexity and enable hardware designers to achieve higher efficiency with smaller form factors in rugged high-power applications. Designers can be further reassured by Nexperia’s proven reputation as a supplier of high-quality products in a range of semiconductor technologies.

This SiC Schottky diode is encapsulated in a Real-2-Pin (R2P) TO-220-2 through-hole power plastic package. Additional package options include the surface mount (DPAK R2P and D2PAK R2P) and through-hole (TO-247-2) with a real 2-pin configuration that enhances reliability in high-voltage applications at temperatures up to 175°C.

Nexperia plans to augment its portfolio of SiC diodes by including automotive-grade parts that operate at 650V and 1200V voltages with currents in the 6-20A range.
