2SD25490P

Overview

The Panasonic 2SD2549P is a silicon NPN triple diffusion planar power transistor designed for power amplification. It features a TO-220D-A1 package with an isolated flange for heat sink mounting. Key electrical ratings include a collector-emitter voltage of 80 V, a continuous collector current of 3 A, and a peak collector current of 5 A. The device dissipates up to 20 W at 25°C case temperature. The 'P' suffix indicates a forward current transfer ratio (hFE) rank of 120 to 250.

Feature Summary

High forward current transfer ratio with satisfactory linearity
Low collector-emitter saturation voltage
Full-pack package allowing installation to a heat sink with one screw

Applications

Power amplification circuits
General electronic equipment
Office equipment
Communications equipment
Measuring instruments

Procurement Notes

Verify the component lifecycle status before procurement, as this part may be classified under maintenance or discontinued stages. Confirm that the specific hFE rank 'P' meets the design requirements. Consult official manufacturer channels for the most up-to-date product standards and availability information prior to finalizing orders.

Selection Notes

Select this component for applications requiring high linearity and low saturation voltage in power amplification. Ensure the thermal management system can handle the 20 W dissipation rating at the specified case temperature. Verify that the 80 V collector-emitter voltage rating exceeds the maximum operating voltage. Consider the TO-220D-A1 package dimensions for PCB layout and heat sink compatibility.

Part Context

This component belongs to the Panasonic 2SD2549 series of silicon NPN transistors. It is specifically engineered for power amplification tasks. The series utilizes a triple diffusion planar process to achieve reliable performance. The device is intended for standard applications in general-purpose electronic equipment rather than specialized safety-critical systems.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-referencing should only be performed using confirmed equivalent components from the manufacturer's database.
