The gate charge is only 0.63 nC at 10 V, and input capacitance measures 15 pF at 50 V drain bias — both low enough for direct GPIO drive in moderate-speed switching up to a few hundred kHz. ## Package and power dissipation Maximum power dissipation is 500 mW at 25°C ambient (Ta), typical for a SOT-23-3 device. The small footprint means thermal management relies on the PCB copper; for continuous loads near the 190 mA limit, ensure adequate trace width and via stitching to the ground plane. The base product number is BSS123, and the IXTMA1 suffix denotes the specific reel and packaging variant.","metaTitle":"Infineon BSS123IXTMA1 N-Channel MOSFET, 100 V, 190 mA","metaDescription":"Infineon BSS123IXTMA1 OptiMOS N-channel MOSFET, 100 V Vdss, 190 mA continuous drain, 6 Ohm Rds(on) at 10 V.

BSS123IXTMA1 is a specific packaging and reel variant of the base BSS123 device. The electrical specifications — 100 V Vdss, 190 mA continuous drain, 6 Ohm Rds(on) at 10 V — are identical to the standard BSS123.
