The 500 mW power dissipation limit and 150°C junction temperature define the thermal budget in compact layouts. ## Saturation voltage and gain — what drives the switching decision Vce saturation is specified at 700 mV maximum with a 50 mA base drive and 500 mA collector current. ## SOT-23-3 footprint — rework-friendly and widely stocked The SOT-23-3 package is one of the most common three-lead surface-mount footprints. It reflows cleanly with a standard lead-free profile and is easy to hand-solder or hot-air rework without lifting pads.","metaTitle":"BC817K-16 NPN transistor, 45 V, 500 mA, SOT-23-3","metaDescription":"BC817K-16 NPN transistor: 45 V Vce, 500 mA Ic, 170 MHz fT, SOT-23-3.
