Product details

100 V, 63 A N-channel in PG-TDSON-8-1 — the switching-loss and thermal budget

The BSC109N10NS3GATMA1: The part lives in an 8-PowerTDFN (PG-TDSON-8-1) surface-mount package with an exposed drain pad for thermal transfer to the board. The junction temperature range of -55 to 150 °C covers automotive under-hood and industrial environments.

That is the worst-case resistance a designer uses for I²R loss calculations at full load.

Gate charge and input capacitance — driver and switching-loss reality

No last-time-buy notice or end-of-life signal is present.

Mounting and thermal — the exposed pad matters

The PG-TDSON-8-1 package is an 8-lead PowerTDFN with a large exposed drain pad on the bottom.

Frequently asked questions

What is the Rds(on) of BSC109N10NS3GATMA1?

The maximum Rds(on) is 10.9 mOhm at a drain current of 46 A with a 10 V gate drive. This is the worst-case on-resistance used for conduction-loss calculations in the power stage.

Is BSC109N10NS3GATMA1 RoHS compliant?

Yes, the part is ROHS3 compliant. It also meets the lead-free requirement — no lead content above the RoHS threshold.

What package does BSC109N10NS3GATMA1 come in?

The package is an 8-PowerTDFN, supplier device code PG-TDSON-8-1.
