80 V, 95 A N-channel — what the ratings mean for the power stage
The Infineon BSC052N08NS5ATMA1 is an 80 V, 95 A N-channel MOSFET from the OptiMOS™ family, in a PG-TDSON-8-7 surface-mount package. The 5.2 mOhm maximum on-resistance at 10 V gate drive keeps I²R losses low at high current. The 40 nC gate charge at 10 V is moderate for this current class.
Temperature range and environment
Rated for junction temperatures from -55°C to 150°C, this part suits automotive under-hood, industrial motor drives, and outdoor telecom power supplies where ambient heat is a factor. The wide temperature span means the thermal design — heatsink, airflow, PCB copper — is the limiting factor, not the silicon junction rating.
Lifecycle and compliance
The BSC052N08NS5ATMA1 carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so it remains a safe choice for new designs and production BOMs. The ROHS3 compliance covers the full substance restriction, which simplifies documentation for EU-market equipment.
