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.
Rds(on) at 10 V — the number that decides conduction loss
The 10.9 mOhm Rds(on) is specified at 10 V gate drive with 46 A drain current. 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
35 nC gate charge at 10 V and 2500 pF input capacitance at 50 V Vds are the numbers a gate-driver designer uses to size the drive current and estimate switching times.
Active lifecycle — no LTB risk for new designs
The BSC109N10NS3GATMA1 carries an Active product status with ROHS3 compliance. 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. The pad must be soldered to a copper area on the PCB to reach the 78 W dissipation rating.
