The 2SA4382 is a high-performance PNP silicon epitaxial planar power transistor from Sanken Electric, specifically designed for high-fidelity audio amplifier output stages. Utilizing Sanken’s proprietary wafer-thinner technology, this device achieves reduced thermal resistance and enhanced power handling in a compact TO-3P package. With a collector-emitter voltage of 230V and a continuous collector current rating of 15A, the 2SA4382 delivers 160W of power dissipation capability, making it well-suited for demanding audio applications. This transistor forms an ideal complementary pair with the 2SC6011A NPN transistor, enabling designers to implement balanced push-pull amplifier configurations with matched electrical characteristics. The device is available in three hFE grades (O, P, Y), allowing for precise gain matching in amplifier circuits. Its low on-chip impedance contributes to improved sound quality, while the high avalanche breakdown rating ensures reliable operation under transient conditions. The 2SA4382 is suitable for both consumer and professional audio equipment, including high-end stereo amplifiers, AV receivers, automotive audio systems, and professional PA amplifiers that may employ parallel-connected output stages for higher power output.

The 2SA4382 is a PNP bipolar junction transistor (BJT) that operates as a current-controlled current amplifier. In a PNP transistor, current flows from the emitter to the collector when the base-emitter junction is forward-biased (with the emitter at a higher potential than the base). The DC current gain (hFE) determines the ratio of collector current to base current, typically ranging from 50 to 180 depending on the hFE grade. In audio amplifier output stages, the 2SA4382 is used in push-pull configurations paired with its NPN complement (2SC6011A), where each transistor conducts during opposite halves of the audio signal cycle. This complementary symmetry arrangement minimizes crossover distortion and enables efficient power delivery to the load. The transistor’s low saturation voltage ensures minimal power loss during conduction, while the high transition frequency (20 MHz typical) provides sufficient bandwidth for full audio frequency reproduction. The epitaxial planar construction supports high voltage breakdown characteristics necessary for high-voltage rail operation in audio amplifiers.
