D44H11G

The D44H11G is an NPN silicon power transistor from On Semiconductor, part of the D44H series. It features a minimum collector-emitter sustaining voltage (VCEO) of 80V and a maximum continuous collector current of 10A, with a peak current rating of 20A under pulse conditions. DC current gain (hFE) is specified as 60 minimum at 2A and 40 minimum at 4A. The collector-emitter saturation voltage is 1V maximum at 8A collector current and 0.4A base current, and the base-emitter saturation voltage is 1.5V maximum at 8A/0.8A. The device offers a transition frequency of 50 MHz and is capable of dissipating 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 junction temperature ranges from -55°C to 150°C. Packaged in a TO-220-3 through-hole case, it is supplied in rails of 50 units. The device is Pb-Free and RoHS3 compliant, making it suitable for general-purpose power amplification and switching applications such as switching regulators, converters, and power amplifiers.
