D44H11 Description

Short technical summary and product information.

The D44H11 is an NPN bipolar junction transistor from STMicroelectronics, part of the D44H series of complementary silicon power transistors. It is designed for general purpose power amplification and switching applications including switching regulators, converters, and power amplifiers.

 

Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 80V, continuous collector current of 10A (peak 20A), and a DC current gain (hFE) of minimum 60 at 2A collector current and 1V VCE. The collector-emitter saturation voltage is typically 1V at 8A collector current.

 

Thermally, the transistor can dissipate up to 70W when the case temperature is held at 25°C, with a junction-to-case thermal resistance of 1.8°C/W. The operating and storage junction temperature range is -55°C to +150°C.

 

The D44H11 is offered in a TO-220-3 through-hole package (supplier device package TO-220), and is RoHS compliant with Pb-free finish.
