D882

D882 is a designation commonly associated with a silicon NPN transistor used in electronics, and is often associated with the broader 2SD882 family in Japanese transistor nomenclature. In many markets the device is sold or labeled simply as D882, while datasheets may list it as 2SD882. The part has seen widespread use in audio amplifiers, switching circuits, and other general-purpose applications.

The D882/2SD882 belongs to the family of NPN power transistors produced by several manufacturers, including Japanese and international suppliers. Variants are offered in multiple package styles appropriate for heat sinking and power handling, such as TO-220 and related power packages. The exact electrical ratings vary by manufacturer, but devices in this class are designed for relatively high voltage and moderate current operation, making them suitable for driver stages, preamp sections, and light to mid-power switching tasks.

Electrical characteristics are specified differently across manufacturers, but typical attributes include a relatively high collector-emitter voltage rating and a few amperes of continuous collector current, with gain that can vary over a wide range depending on process and temperature. Designers must consult the specific datasheet for precise values, as results can differ between manufacturers and batches. Cooling and bias stability are common design considerations when using this type of transistor.

In contemporary designs, MOSFETs and newer transistors often replace older BJT devices for power or switching roles. Nevertheless, the D882/2SD882 remains encountered in vintage equipment and in contexts where its legacy characteristics are suitable. See also 2SD882 and related 2S prefix transistor families.
