2SA1673

Single Bipolar Transistors Overview

The Sanken Electric 2SA1673 is a silicon PNP epitaxial planar transistor designed for audio and general-purpose applications. It serves as the complement to the 2SC4388 NPN device. The component features a maximum collector-emitter voltage of -180 V and a continuous collector current rating of -15 A. Maximum power dissipation reaches 85 W at a case temperature of 25 °C. The unit utilizes an FM100 (TO-3P) flange mount package with isolated mounting characteristics. Electrical specifications include a minimum DC current gain of 50 and a typical transition frequency of 20 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (O, P, or Y) required for your circuit design, as these indicate different gain ranges. Confirm that the ordering information matches the exact electrical characteristics needed for your application. Ensure compatibility with the complementary 2SC4388 device if used in paired configurations. Check for any regional compliance markings on the datasheet version being referenced.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage PNP transistor with significant current capacity is required. The -180 V breakdown voltage allows for operation in higher voltage audio or industrial systems. Consider the TO-3P package size for mechanical integration. Pairing with the 2SC4388 ensures matched characteristics for balanced push-pull operation. Evaluate thermal management requirements based on the 85 W dissipation limit.

Single Bipolar Transistors Part Context

This transistor belongs to Sanken's lineup of high-power bipolar devices intended for robust electronic designs. The FM100 package provides a reliable interface for heat sinking. As a PNP type, it complements NPN counterparts to form complete output stages. The epitaxial planar construction supports stable operation across varying temperatures.

Single Bipolar Transistors Replacement Considerations

The 2SC4388 is the designated complementary NPN transistor for paired operation. Direct substitution requires verifying pinout compatibility and ensuring the replacement meets the -180 V and -15 A ratings. No other direct substitutes are officially documented.
