2SD2401

Overview

The Sanken 2SD2401 is a Silicon NPN Triple Diffused Planar Transistor designed for audio, series regulator, and general-purpose applications. It features a Darlington configuration with built-in bias resistors in an MT-200 package. Absolute maximum ratings include a collector-emitter voltage of 150 V, collector current of 12 A, and power dissipation of 1 W at 25°C case temperature. Electrical characteristics specify a minimum DC current gain (hFE) of 5000 at IC=7A, VCE=4V, and a typical cut-off frequency of 55 MHz.

Feature Summary

Triple diffused planar construction for robust performance
Integrated Darlington structure with built-in bias resistor
High DC current gain suitable for amplification stages

Applications

Audio amplifier circuits
Series voltage regulators
General purpose switching and amplification

Procurement Notes

Verify the component datasheet directly from Sanken Electric to confirm electrical parameters and physical dimensions. Ensure the specific hFE rank matches design requirements, as gain varies by suffix. Confirm compliance with environmental standards such as RoHS before procurement. Check for availability status as this component may be restricted for new designs.

Selection Notes

Select the 2SD2401 when high current gain and moderate voltage handling are required in a single package. The integrated bias resistor simplifies drive circuitry compared to discrete Darlington pairs. Consider thermal management carefully due to low power dissipation limits without a heatsink. Verify that the MT-200 package fits the mechanical constraints of the target application.

Part Context

This component serves as the complementary pair to the 2SB1570 PNP transistor. It belongs to Sanken's lineup of power transistors intended for linear and switching applications. The triple diffused planar technology provides improved reliability over older manufacturing methods.
