80V N-channel in a PG-TSON-8-3 — what it delivers
It carries a continuous drain current of 237A at the case (Tc) and 28A at ambient (Ta), with a maximum Rds(on) of 1.9 mOhm at 50A and 10V gate drive. The PG-TSON-8-3 footprint (8-PowerTDFN) keeps the board area tight for surface-mount power stages.
Infineon lists this part as Active (current production) and ROHS3 compliant. No end-of-life notices or last-time-buy schedules are on record.
PG-TSON-8-3 footprint and thermal management
The PG-TSON-8-3 package (also listed as 8-PowerTDFN) is a surface-mount power package with an exposed drain pad for thermal dissipation. Power dissipation is rated at 3W at ambient (Ta) and 214W at the case (Tc) — the wide spread reflects the difference between free-air convection and a properly heatsunk PCB layout. Input capacitance (Ciss) is 8600 pF at 40V Vds, which sets the gate-drive current requirement for a given rise time.
