ASFETs for hot-swap and soft-start

Author: EIS Release Date: Mar 31, 2023

Nexperia is shipping  80V and 100V application-specific MOSFETs (ASFETs) for hotswap with enhanced safe operating area (SOA) in an 8×8 mm LFPAK88 package.

 

These ASFETs are  optimized for demanding hotswap and soft-start applications and are qualified to 175°C for use in advanced telecom and computing equipment.

 

Nexperia’s PSMN2R3-100SSE (100 V, 2.3 mΩ N-channel ASFET) is the leading addition in the portfolio, delivering low RDS(on) and strong linear-mode (safe operating area) performance in a compact 8×8 mm footprint, tailored to meet the requirements of demanding hotswap applications.

 

Nexperia has also released PSMN1R9-100SSE (80 V, 1.9 mΩ), an 80 V ASFET which responds to the growing trend for using 48 V power rails in computing servers and other industrial applications where environmental conditions allow for MOSFETs with a lower BVDS rating.
