onsemi High- and Low-Voltage MOSFETs Found Inside FSP 800W CRPS Server Power Supply
2026-08-22 · Compiled by Best IT Parts from public industry reporting
Server power supplies operate under sustained high load, placing demanding requirements on power devices in terms of voltage withstand, conduction loss, switching performance, and long-term reliability. Inside FSP's 800W CRPS server power supply, onsemi high- and low-voltage MOSFETs have been identified across both sides of the design — from the high-voltage PFC stage to the isolated power conversion stages. The article details which onsemi device families are used, how they are deployed across the PFC, switching, and output stages, and the performance and reliability considerations that drive component selection in enterprise-grade CRPS power platforms. For server PSU manufacturers, component distributors, and B2B buyers sourcing power semiconductors, this adoption is a concrete reference on the MOSFET platforms proving themselves in high-reliability, high-density server power designs.
