BD788G

The BD788G is a PNP silicon power transistor manufactured by onsemi (formerly ON Semiconductor). It is designed for lower power audio amplifier and low current, high-speed switching applications. The device features a collector-emitter voltage rating of 60V, a collector-base voltage of 80V, and an emitter-base voltage of 6V. It can handle a continuous collector current of 4A with a peak current capability of 8A, and a continuous base current of 1A.

With a total power dissipation of 15W at a case temperature of 25°C, the BD788G provides adequate thermal headroom for moderate power applications. The DC current gain ranges from 40 to 250 at a collector current of 200mA and collector-emitter voltage of 3V, with a minimum gain of 25 at 1A and 20 at 2A. The collector-emitter saturation voltage is a maximum of 2.5V at a base current of 800mA and collector current of 4A. The transition frequency is 50MHz.

The device operates over a junction temperature range of -65°C to 150°C and has a thermal resistance from junction to case of 8.34°C/W. It is packaged in a TO-225 (TO-225AA, TO-126-3) through-hole package with a supplier device package of TO-126. The BD788G is Pb-Free and RoHS compliant, and is shipped in boxes of 500 units.
