Nexperia B.V. Bipolar Transistor, Npn, 45V, 500Ma, 3-Sot-23, Full Reel; Transistor Polarity Nexperia BC817-40,215.

NPN general-purpose transistor for switching and amplification, available in SOT23 surface-mounted package, with a collector-emitter voltage rating of 45 V, a continuous collector current of 500 mA, a peak collector current of 1 A, and a total power dissipation of 250 mW at 25 °C. The DC current gain (hFE) ranges from 250 to 600 at a collector current of 100 mA and a collector-emitter voltage of 1 V. Collector-emitter saturation voltage is 700 mV maximum at a collector current of 500 mA and a base current of 50 mA. The device is mounted on an FR4 printed-circuit board with a standard footprint and meets the IEC 60134 Absolute Maximum Rating System. Thermal resistance from junction to ambient is 500 K/W. The part number BC817-40,215 corresponds to a 4 mm pitch, 8 mm tape and reel packing variant of the BC817-40 model.
