Diotec Semiconductor Single Bipolar Transistors MPSA42BK

The MPSA42BK is a high-voltage NPN transistor in a TO-92 package, designed for signal processing, switching, and amplification applications. It features a collector-emitter voltage rating of 300 V and a continuous collector current of 500 mA, with a maximum power dissipation of 625 mW. The device is mounted in bulk format with a 1.27 mm pitch, indicated by the "BK" suffix. Junction temperature ranges from -55°C to +150°C. It is RoHS compliant, REACH compliant, and meets AEC-Q101 standards when designated with the -Q or -AQ suffix. Thermal resistance junction to ambient is less than 200 K/W. The case material is UL 94V-0 rated. Recommended complementary PNP transistor is the MPSA92.
