2SD2643

Overview

The Sanken 2SD2643 is a silicon NPN triple diffused planar transistor designed for audio, series regulator, and general-purpose applications. It features a Darlington configuration with a built-in bias resistor in an FM100 (TO-3PF) package. Key electrical ratings include a collector-emitter voltage of 110 V, a maximum collector current of 6 A, and a minimum DC current gain of 5000 at IC=5A. The device supports a maximum power dissipation of 60 W at 25°C case temperature.

Feature Summary

Darlington configuration integrated with a built-in bias resistor
Triple diffused planar silicon construction
High DC current gain suitable for low drive requirements

Applications

Audio amplifier circuits
Series voltage regulators
General purpose switching applications

Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your design, as these denote distinct gain ranges. Confirm compliance with RoHS standards and lead-free specifications during sourcing. Ensure thermal management aligns with the specified derating curves for safe operation.

Selection Notes

Select this component for high-gain amplification tasks requiring minimal base drive current. Consider the TO-3PF flange mount package for effective heat dissipation in power applications. Evaluate the saturation voltage characteristics against load requirements to ensure efficient switching performance.

Part Context

This transistor serves as the complementary pair to the 2SB1687 PNP type. It belongs to Sanken's line of power transistors optimized for linear and switching operations. The device utilizes a plastic epoxy encapsulation with an isolated mounting base for direct heatsink attachment.
