New 80V/100V MOSFETs with Latest Silicon Technology for Power Supply, Telecom and Industrial Designs

Nexperia has announced new Qrr Figure of Merit 80 V / 100 V MOSFETs with latest NextPower silicon technology which will expand the capacity for immediate supply. The new PSMN3R9-100YSF (100 V) and PSMN3R5-80YSF (80 V) devices are ideally suited for power supply, telecom and industrial designs, especially suiting USB-PD Type-C chargers and adaptors and 48 V DC-DC adaptors. These devices feature low body diode losses with Qrr down to 50 nC - resulting in lower reverse recovery current (Irr), lower voltage spikes (Vpeak) and reduced ringing which allows for further optimised dead-time.

The NextPower 80 V and 100 V silicon MOSFETs significantly improve RDS(on) from 7 mΩ for previous generation 100 V parts down to just 4.3 mΩ for the new devices, resulting in increased efficiency. The NextPower technology also delivers best-in-class low Qrr of 44 nC for the 100 V part which reduces spiking and EMI emissions. Overall, the Qrr Figure of Merit for the 100 V part is 61% lower on average than competitive devices.

Mike Becker, Nexperia’s product manager said that, “With the global shortage of semiconductors, the investments made by Nexperia to increase capacity across its global manufacturing sites, including Manchester & the Philippines where these MOSFETs are produced, will be very welcome news to buyers. Designers will also be excited by the performance of the new MOSFETs. They are very well suited to many switching applications, and are genuine second source options to other vendors’ products.”
