onsemi D45H11G 80V 10A PNP Power Transistor TO-220

The onsemi D45H11G is an 80V, 10A PNP silicon power bipolar transistor in a 3-lead TO-220 through-hole package. It is designed for low collector-emitter saturation voltage and fast switching in general-purpose power amplification, switching regulators, converters, driver stages, and power-amplifier applications. Its complementary NPN device is the D44H11G.

The device is rated for 80V collector-emitter voltage, 5V emitter-base voltage, and 10A continuous collector current. Peak collector current reaches 20A under the specified pulse-width and duty-cycle conditions.

DC current gain is at least 60 at IC = 2A and VCE = 1V, and at least 40 at IC = 4A. Maximum collector-emitter saturation voltage is 1.0V at IC = 8A and IB = 0.4A, while maximum base-emitter saturation voltage is 1.5V at IC = 8A and IB = 0.8A.

For dynamic performance, the D45H series provides approximately 40MHz gain-bandwidth product at the specified 0.5A/10V test point and about 160pF typical collector capacitance. Typical switching characteristics for the PNP series include 135ns delay-plus-rise time, 500ns storage time, and 100ns fall time under the specified 5A test conditions.

Maximum power dissipation is 70W at TC = 25°C, with junction-to-case thermal resistance of 1.8°C/W maximum. Junction and storage temperature range is -55°C to +150°C. The D45H11G uses a Pb-free TO-220 package and is supplied in 50-piece rails.
