Product details

650 V, 8.7 A — the switching load envelope

The IPA65R420CFD: Input capacitance is 870 pF at 100 V drain-source, which sets the switching transition times and the drive current needed for fast edges.

TO-220 Full Pack — isolated tab simplifies heatsinking

The PG-TO220-3-111 (TO-220 Full Pack) through-hole package has a fully isolated metal tab — no insulating pad or washer is needed between the tab and the heatsink, which cuts assembly time and eliminates the thermal interface gap. The junction temperature range spans -55°C to 150°C, so the part handles the thermal cycling of industrial power supplies and lighting ballasts without derating at the cold end.

CoolMOS CFD2 — fast body diode for bridge topologies

This device belongs to the CoolMOS CFD2 series, which features an optimized fast body diode with reduced reverse-recovery charge (Qrr). That makes it a good fit for phase-shifted full-bridge, LLC resonant, and other topologies where the MOSFET's own body diode conducts during dead time.

Frequently asked questions

What is the closest pin-compatible alternative to IPA65R420CFD?

No official pin-compatible second source is listed in the record. The CoolMOS CFD2 series includes other voltage/current variants in the same TO-220 Full Pack footprint, but each has different Rds(on) and current ratings — confirm the parametric match against your BOM before substituting.

What compliance documentation does Infineon provide for IPA65R420CFD?

The evidence does not list specific compliance certificates. Infineon typically provides RoHS and REACH declarations for this series — request the latest compliance documents with your RFQ.
