The BC817-40 is an NPN general-purpose transistor from Nexperia, housed in a small SOT-23 (TO-236AB) surface-mount package. It is designed for general-purpose switching and amplification applications.
Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of 45V, a continuous collector current (IC) of 500mA, and a peak collector current of 1A. The DC current gain (hFE) for the BC817-40 selection group ranges from 250 to 600 at VCE = 1V and IC = 100mA. The collector-emitter saturation voltage (VCEsat) is maximum 700mV at Ib = 50mA and Ic = 500mA.
Total power dissipation is 250mW when mounted on a standard FR4 PCB footprint (345mW with a 1cm² collector pad). The junction temperature range extends to 150°C, and the device can be stored or operated in ambient temperatures from -65°C to 150°C. The transistor is RoHS3 compliant (unverified) and has MSL Level 1 (unlimited) moisture sensitivity. Common applications include signal amplification, switching circuits, and low-power driver stages.
