The BD138 is a PNP epitaxial silicon transistor from STMicroelectronics, part of the BD136 series. It is designed for medium power amplification and switching applications. Key electrical characteristics include a maximum collector-emitter voltage (VCEO) of -60V, collector-base voltage (VCBO) of -80V, and a continuous collector current (IC) of -1.5A (pulse up to -3.0A). The DC current gain (hFE) ranges from 40 to 250 depending on the suffix, with a minimum of 40 at 150mA and 2V. The collector-emitter saturation voltage (VCE(sat)) is typically -0.5V at 500mA. Power dissipation is 12.5W at case temperature 25°C and 1.25W at ambient 25°C. The device is housed in a through-hole SOT32-3 package (TO-225AA / TO-126-3) and is Pb-Free. It operates over a junction temperature range up to 150°C and can be stored from -55°C to 150°C. The BD138 is the complement to the NPN BD135 transistor, making it suitable for push-pull and complementary circuit designs.
