The IPAN70R900P7SXKSA1: The 700 V Vdss rating provides headroom over a typical 400 VDC bus in PFC stages. The 900 mOhm Rds(on) at 10 V gate drive and 6.8 nC gate charge at 10 V keep gate-drive losses low in fast-switching applications.
The TO-220 Full Pack (PG-TO220-FP) is a through-hole package with a fully molded, isolated backside. No mica washer or sil-pad is needed between the tab and the heatsink, which cuts assembly time and eliminates one thermal interface. The three leads are standard TO-220 spacing; verify the existing PCB footprint matches the PG-TO220-FP pinout before committing the layout.
The IPAN70R900P7SXKSA1 is an active product with ROHS3 compliance. The CoolMOS™ P7 series is Infineon's current-generation high-voltage MOSFET platform. The base product number is IPAN70.
