The BC639 is an NPN silicon bipolar junction transistor designed for general purpose switching and amplification. It offers a collector-emitter voltage rating of 80V and a continuous collector current of 1A, making it suitable for medium power applications.
Electrical characteristics include a minimum DC current gain (hFE) of 40 at 150mA collector current and 2V collector-emitter voltage, and a gain bandwidth product of 200 MHz. The maximum collector-emitter saturation voltage is 500mV at 500mA collector current and 50mA base current.
The transistor is housed in a through-hole TO-92 package (TO-226-3, TO-92-3 Long Body) with a junction temperature range of -55°C to +150°C. Thermal resistance junction-to-ambient is 200°C/W and junction-to-case is 83.3°C/W.
Typical applications include driver stages, linear amplifiers, and medium power switching circuits. The device is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited).
