Product details

The Infineon SPB20N60C3ATMA1 is an N-channel CoolMOS™ power MOSFET rated for 650 V drain-source voltage and 20.7 A continuous drain current at 25 °C case temperature. Gate charge of 114 nC at 10 V tells the driver what it has to push each cycle — a figure that sizes the gate resistor and drive current for the target switching frequency. The PG-TO263-3-2 (D²Pak) surface-mount package suits automated assembly on an aluminium-core or IMS PCB for thermal management.

That 150 °C limit governs the derating curve — at case temperatures above 25 °C the 20.7 A figure drops, and the 208 W power dissipation rating (Tc) is what the thermal design must stay under. For outdoor telecom rectifiers or industrial motor drives with limited airflow, this part keeps headroom.

Surface-mount in the TO-263-3 / D²Pak footprint. The supplier device package is PG-TO263-3-2, which is the Infineon code for the same outline.

ROHS3 compliant. The series is CoolMOS™, Infineon's high-voltage MOSFET platform.

Frequently asked questions

Is SPB20N60C3ATMA1 RoHS compliant?

Yes, it is ROHS3 compliant per the Infineon listing.

What is the gate charge of SPB20N60C3ATMA1?

Total gate charge (Qg) is 114 nC at 10 V gate drive. That figure drives the switching loss calculation and gate driver sizing.

Can SPB20N60C3ATMA1 replace SPB20N60C3?

The SPB20N60C3ATMA1 is the Tape & Reel packaged variant of the SPB20N60C3 base part. The die and electrical ratings are identical — same CoolMOS C3 technology, same 650 V / 20.7 A / 190 mOhm specs. The suffix indicates the reeled packaging format for automated assembly.
