D45H8G

The D45H8G is a PNP silicon power transistor from On Semiconductor, part of the complementary D45H series. It is designed for general purpose power amplification and switching applications such as output or driver stages in switching regulators, converters, and power amplifiers. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 60 V, continuous collector current of 10 A, and peak current of 20 A. The device offers low collector-emitter saturation voltage (1 V max at 8 A) and fast switching speeds. DC current gain (hFE) is a minimum of 60 at 2 A/1 V and 40 at 4 A/1 V. The transistor is housed in a TO-220-3 through-hole package, suitable for easy mounting on heatsinks. Thermal characteristics include a maximum power dissipation of 70 W at case temperature 25°C and 2.0 W at ambient temperature 25°C, with junction-to-case thermal resistance of 1.8°C/W. The operating junction temperature range is -55°C to 150°C. The D45H8G is RoHS3 compliant and Pb-Free, making it suitable for environmentally sensitive designs.
