Product details

40 V N-channel in the OptiMOS™ line — what the ratings mean for the board

Its headline figure is a maximum Rds(on) of 1.9 mOhm at 50 A and 10 V gate drive — that puts it in the sub-2 mOhm tier for a 40 V part, sized for high-current rails in telecom, server, and industrial power stages. Gate charge is 41 nC at 10 V — moderate for this current class.

Package and mounting — the thermal land pattern is part of the spec

The BSC019N04LSATMA1 is supplied in an 8-PowerTDFN case, Infineon's PG-TDSON-8-1 footprint.

The junction temperature range spans -55 °C to 150 °C.

It is ROHS3 compliant.

Frequently asked questions

Is BSC019N04LSATMA1 equivalent to BSC019N04LS?

The BSC019N04LSATMA1 is the Tape & Reel variant of the base BSC019N04LS device. The die and electrical ratings are identical; the suffix indicates the shipping format.

Is BSC019N04LSATMA1 lead-free?

Yes — the BSC019N04LSATMA1 is ROHS3 compliant, meeting the current lead-free and RoHS exemption requirements.
