The 170 MHz transition frequency suits medium-speed switching and linear driver stages. Maximum power dissipation is 500 mW. The hFE minimum of 160 at 100 mA, 1 V means this part delivers consistent gain in the linear region for pre-driver or relay-coil drive circuits. The VCE(sat) maximum of 700 mV at 50 mA base current and 500 mA collector current defines the on-state voltage drop when fully saturated — relevant for estimating power loss in a switched load. Collector cutoff current is 100 nA maximum, which keeps leakage negligible in high-impedance off-state paths. ## Package and mounting — SOT-323 footprint The SC-70 / SOT-323 case (PG-SOT323-3-1) is a three-lead surface-mount package. The 500 mW power limit assumes standard PCB copper area; thermal performance depends on board layout and ambient. The junction temperature rating of 150 °C sets the upper bound for die temperature under load.","metaTitle":"BC817K-25WE6327 NPN transistor, AEC-Q101, 45 V, 500 mA","metaDescription":"BC817K-25WE6327 NPN transistor, AEC-Q101 qualified, 45 V VCEO, 500 mA Ic, hFE min 160 at 100 mA, 170 MHz fT.
