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. The ±20 V maximum gate-source rating gives margin for ringing on long traces. ## 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. ## Lifecycle and sourcing 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.
