Product details

30 V N-channel power MOSFET for low-voltage switching

The Infineon BSC119N03MSCG is a 30 V N-channel power MOSFET from the OptiMOS™3 series, built on a metal-oxide trench technology. It delivers a maximum continuous drain current of 39 A at the case (Tc) and 11 A at ambient (Ta), with a typical on-resistance of 11.9 mOhm at 10 V gate drive and 30 A. The PG-TDSON-8 package (8-PowerTDFN) includes an exposed pad for thermal management, supporting up to 28 W power dissipation at the case.

Input capacitance (Ciss) is 1500 pF at 15 V drain-source, giving a moderate gate-drive load that a standard gate-driver IC can handle without excessive peak current. The threshold voltage (Vgs(th)) maximum is 2 V at 250 µA, ensuring the device turns on cleanly with logic-level gate signals.

For volume production or urgent BOM fills, submit an RFQ to verify lead time and stock position.

Frequently asked questions

Does BSC119N03MSCG have a drop-in replacement?

No direct drop-in replacement is listed in the official records. The IPD50R950CEAUMA1 is a different voltage class (500 V) and much higher Rds(on) (950 mOhm), so it is not a functional substitute for this 30 V low-Rds(on) MOSFET.

Where can I buy BSC119N03MSCG with immediate stock?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — stock and lead time are confirmed at quote time.
