Product details

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.

Frequently asked questions

Is BSC019N08NS5ATMA1 RoHS compliant?

Yes — the part is ROHS3 compliant per Infineon's listing.

What is the difference between BSC019N08NS5ATMA1 and BSC019N08NS5AT?

The suffix 'ATMA1' indicates a specific tape-and-reel packaging variant (Tape & Reel) and possibly a different reel quantity or packing specification. The die, electrical ratings, and package (PG-TSON-8-3) are identical. For most designs, the two are interchangeable; the 'ATMA1' variant is the standard reeled option for automated assembly.

Is BSC019N08NS5ATMA1 a direct replacement for BSC020N08NS5?

The BSC019N08NS5ATMA1 has a lower Rds(on) (1.9 mOhm vs the BSC020N08NS5's typical 2.0 mOhm) and shares the same 80V Vdss, PG-TSON-8-3 package, and OptiMOS 5 technology. It is a direct drop-in replacement with slightly lower conduction loss — no board or layout changes needed.
