The BC638TA is a PNP epitaxial silicon transistor designed for switching and amplifier applications. It is the complement to the BC637 NPN transistor. Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of -60V, continuous collector current of -1A, and peak collector current of -1.5A. The DC current gain (hFE) ranges from 40 to 160 at VCE = -2V and IC = -150mA. Collector-emitter saturation voltage is 500mV maximum at IC = -500mA and IB = -50mA. The current gain bandwidth product (fT) is 100 MHz typical. Power dissipation is 1W at 25°C ambient, with a junction-to-ambient thermal resistance of 125°C/W. The device is housed in a through-hole TO-92-3 (TO-226AA) package with formed leads. It is RoHS3 compliant, Pb-Free, and Halogen Free/BFR Free. Standard packaging is fan-fold with 2000 units per package.
