Description

The D882 is NPN silicon transistor suited for the output stage of 3 watts audio amplifier, voltage regulator, DC-DC converter and relay driver. The NEC 2SD822 is an NPN silicon power transistor rated at VCEO=30V and IC=3A, designed in a TO-220-style package for medium-power switching and amplification. It offers good current gain, low saturation voltage, and reliable thermal performance for linear and switching operation. This transistor is commonly used in audio power stages, DC motor drivers, and general-purpose power control circuits.

Features

1. Low saturation voltage.

2. Excellent hFE linearilty and high hFE

3. Less cramping space required due to small and thin package and reducing the trouble for attachement to a radiator. NO insulator bushing required.
