2SD2438

Overview

The Sanken Electric 2SD2438 is a Silicon NPN Triple Diffused Planar Transistor designed for audio, series regulator, and general-purpose applications. It features a Darlington configuration with a minimum DC current gain (hFE) of 5000. Absolute maximum ratings include a collector-emitter voltage (VCEO) of 150 V, a collector-base voltage (VCBO) of 160 V, and a continuous collector current (IC) of 8 A. The device supports a total power dissipation of 75 W at a case temperature of 25°C and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

Darlington configuration providing high current gain
Triple diffused planar construction for reliability
High collector current capability suitable for power amplification

Applications

Audio output stages
Series regulators
General purpose switching

Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these denote distinct gain ranges. Confirm that the FM100 (TO-3PF) package dimensions match your thermal management and mounting constraints. Ensure compliance with the manufacturer's recommendation against using this component in new designs before finalizing procurement.

Selection Notes

Select the 2SD2438 when a high-gain NPN transistor is needed for audio or linear regulation tasks requiring up to 8 A. Consider the complementary 2SB1587 for push-pull configurations. Evaluate the thermal resistance characteristics and safe operating area curves to ensure adequate heat sinking for the intended load conditions.

Part Context

This component belongs to Sanken Electric's lineup of silicon NPN triple diffused planar transistors. It serves as the complement to the 2SB1587 PNP type. The device utilizes a TO-3PF (FM100) flange mount package, which facilitates direct mounting to heatsinks for efficient thermal dissipation in high-power applications.

Replacement Considerations

The datasheet explicitly identifies the 2SD2438 as not recommended for new designs. Verify if newer Sanken alternatives are available for any fresh development projects.
