D45H11 Description

Short technical summary and product information.

The D45H11 is a PNP bipolar junction transistor designed for high-current switching and amplification applications. It features a collector-emitter voltage rating of 80V and a continuous collector current of 10A, making it suitable for a wide range of power control circuits.

 

With a minimum DC current gain (hFE) of 40 at 4A and 1V VCE, the D45H11 provides reliable gain for linear operation. The maximum collector-emitter saturation voltage is 1V at 8A collector current and 400mA base current, ensuring low on-state losses in switching designs.

 

The transistor supports a power dissipation of up to 50W and an operating junction temperature of 150°C. It is offered in a TO-220-3 through-hole package, which facilitates heat sinking and easy PCB mounting in conventional designs.
