Infineon Power Devices Cover Both Critical Stages in Acbel 1600W Platinum Server Power Supply
2026-09-01 ยท Compiled by Best IT Parts from public industry reporting
A professional teardown reveals that Acbel's 1600W 80PLUS Platinum server power supply R1CA2162A uses Infineon CoolSiC silicon carbide diodes and low-resistance power MOSFETs for PFC rectification and secondary synchronous rectification โ the two stages that most directly determine efficiency and thermal performance in high-power server PSUs. The unit accepts 200-240V AC input and delivers 1600W rated output (12V/133A main rail plus 12V/3A standby) through a PFC + phase-shifted full-bridge + synchronous rectification architecture. On the primary side, the IDH12G65C6 CoolSiC G6 SiC Schottky diode (650V, 12A, PG-TO220-2) handles PFC boost rectification with zero reverse recovery charge and high dv/dt tolerance; on the secondary side, the BSC016N06NS 60V OptiMOS MOSFET with just 1.6mฮฉ Rds(on) minimizes conduction losses under the 133A low-voltage high-current output. For server PSU distributors, OEMs, and B2B buyers sourcing high-efficiency power platforms, this teardown documents a real-world reference design for SiC-based high-power-density server power.
