That qualifies it for under-hood electronics, outdoor telecom, and any environment where the PCB sees thermal cycling from cold soak to hot shutdown. The package is SC-70 / SOT-323 (supplier code PG-SOT323), a three-lead surface-mount outline with a 1.3 mm × 2.0 mm footprint — small enough to fit in a dense mixed-signal layout alongside passives and logic, but large enough for hand-solder rework in prototyping.","metaTitle":"Infineon BSS138WH6433XTMA1 N-Ch MOSFET, 60V, 280mA, SOT323","metaDescription":"Infineon BSS138WH6433XTMA1 SIPMOS N-channel MOSFET, 60V Vdss, 280mA Id, 3.5 Ohm Rds(on) at 10V.
