The BC637 is an NPN epitaxial silicon bipolar junction transistor designed for general-purpose switching and amplifier applications. It offers a maximum collector-emitter voltage (VCEO) of 60V and a continuous collector current rating of 1A, with a peak current capability of 1.5A. The DC current gain (hFE) ranges from 40 to 160 at a test condition of VCE=2V and IC=150mA, providing good amplification linearity.
This transistor features a current gain bandwidth product (ft) of 100MHz typical, making it suitable for low-frequency amplifier stages and moderate-speed switching circuits. Collector-emitter saturation voltage is 500mV maximum at IC=500mA and IB=50mA, ensuring low power dissipation in saturation.
The BC637 is housed in a through-hole TO-92 (TO-226) package, which allows easy insertion on printed circuit boards and prototyping. The operating junction temperature range is -55°C to 150°C, and the device is capable of dissipating up to 1W of power. It is a complement to the PNP types BC636, BC638, and BC640.
