2SD2389

Overview

The Sanken Electric USA Inc. 2SD2389 is a silicon NPN triple diffused planar transistor designed for audio, series regulator, and general-purpose applications. It features an absolute maximum collector-emitter voltage of 150 V and a continuous collector current rating of 8 A at 25°C case temperature. The device provides a minimum DC current gain (hFE) of 150 at IC=30mA and up to 5000 under high-current conditions. Electrical characteristics include a typical transition frequency (fT) of 80 MHz and a saturation voltage of 2.5 V max at IC=6A. Power dissipation reaches 80 W with an infinite heatsink.

Feature Summary

Triple diffused planar construction for robust performance
High current handling capability suitable for power regulation
Complementary pairing available with the 2SB1559 PNP type

Applications

Audio amplifier circuits
Series voltage regulators
General-purpose switching applications

Procurement Notes

Verify component authenticity against official Sanken datasheets before integration. Confirm that the MT-100 (TO-3P) package dimensions match the design footprint. Ensure thermal management solutions support the specified 80 W power dissipation limits. Check for end-of-life status or obsolescence warnings prior to final procurement decisions.

Selection Notes

Select this component for designs requiring high current capacity and moderate voltage ratings. Consider the complementary 2SB1559 for push-pull configurations. Evaluate thermal resistance requirements carefully, as performance depends on heatsinking. Verify hFE binning if specific gain ranges are critical for the circuit operation.

Part Context

This NPN transistor belongs to Sanken's discrete power transistor lineup. It serves as a complement to the 2SB1559 PNP device. The technology utilizes triple diffused planar processes to ensure reliability in power electronics. It is categorized under general-purpose and audio application transistors.
