What this OptiMOS™ N-channel does in a switching circuit
The Infineon IPD35N10S3L26ATMA1 is a 100 V, 35 A N-channel MOSFET from the OptiMOS™ family, in a TO-252-3 (DPak) surface-mount package. It's built for hard-switching DC-DC converters, motor drives, and power-supply rails where conduction loss matters — the 24 mOhm Rds(on) at 10 V gate drive keeps I²R losses low at the 35 A continuous drain rating. Gate charge is 39 nC at 10 V, a moderate figure that balances switching speed against gate-drive power. The junction temperature range of -55°C to 175°C extends past the usual industrial ceiling, so it handles the thermal cycling in under-hood automotive or high-ambient enclosure environments without derating surprises.
Active lifecycle — no LTB clock ticking
This part carries an Active product status from Infineon. ROHS3 compliant per, and the standard TO-252 footprint is compatible with lead-free reflow profiles. For volume procurement, the part is available through independent distribution channels; pricing and lead time are confirmed at quote time against an RFQ.
Mounting and thermal notes for the TO-252
The PG-TO252-3-11 supplier package has the tab as the drain terminal — the PCB land pattern must connect the tab pad to a thermal relief or copper pour.
