It is designed for switching and linear-mode applications where the load current stays under 100 mA — think relay and solenoid drivers, DC-DC converter auxiliary rails, or level shifters in industrial control boards. ## On-resistance and drive voltage — the trade-off Rds(on) is specified at 14 Ohm maximum with 10 V gate drive and 100 mA drain current. That is a high enough resistance that the part is not meant for continuous power delivery — the 360 mW package dissipation limit is the real constraint. ## Temperature range and package fit The gate charge is just 2.3 nC at 5 V, so a microcontroller GPIO can drive the gate directly without a pre-driver.","metaTitle":"BSS139IXTSA1 N-Channel MOSFET, 250 V, 100 mA, SOT-23-3","metaDescription":"BSS139IXTSA1 N-channel MOSFET from Infineon, 250 Vdss, 100 mA Id, 14 Ohm Rds(on) at 10 V.
