STMICROELECTRONICS D44H8 Power Transistor

These power transistors are manufactured using low voltage multi-epitaxial planar technology, suitable for general-purpose linear and switching applications such as power amplification and switching circuits. Available in TO-220 packages, they feature low collector-emitter saturation voltage, fast switching speeds, and high collector current capacity of up to 10 A. The devices include both NPN and PNP types, with collector-emitter voltages up to 80 V, making them ideal for various power management and electronic switching needs. Their thermal ratings support robust operation within specified temperature ranges.
