2SA1492

Single Bipolar Transistors Overview

The Sanken Electric USA Inc. 2SA1492 is a silicon PNP epitaxial planar transistor designed for audio and general-purpose applications. It serves as the complement to the 2SC3856 NPN type. Key absolute maximum ratings include a collector-base voltage (VCBO) of -180 V, a collector-emitter voltage (VCEO) of -180 V, and an emitter-base voltage (VEBO) of -6 V. The device supports a continuous collector current (IC) of -15 A and dissipates up to 130 W at a case temperature of 25°C. Electrical characteristics specify a minimum DC current gain (hFE) of 50, with ranks O (50-100), P (70-140), and Y (90-180). The transition frequency (fT) is typically 20 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (O, P, or Y) required for your application during procurement, as gain varies significantly across these bins. Confirm the MT-100 (TO-3P) package availability and ensure thermal management solutions are compatible with the 130 W power rating. Check for updated datasheet revisions to confirm electrical characteristic consistency.

Single Bipolar Transistors Selection Notes

Select the 2SA1492 when a high-voltage PNP transistor is needed to match the 2SC3856. Ensure the operating collector current remains within the -15 A limit and that the junction temperature stays below 150°C. Consider the thermal resistance characteristics for heatsink sizing, especially if operating without an infinite heatsink where power derating applies.
