2N5447 TRE PBFREE

Overview

The Central Semiconductor Corp 2N5447 TRE PBFREE is a PNP bipolar junction transistor (BJT) designed for audio frequency applications. It features a maximum collector-emitter voltage of 25 V, a continuous collector current of 200 mA, and a transition frequency of 100 MHz. The device dissipates up to 625 mW of power and utilizes a TO-92-3 through-hole package.

Feature Summary

• Epitaxial planar silicon construction with epoxy molding
• Optimized performance for audio frequency circuits
• Through-hole mounting capability in standard TO-92-3 form factor

Applications

• Audio amplifier stages
• General-purpose switching circuits
• Low-power signal processing

Procurement Notes

Verify the specific 'TRE' suffix against the manufacturer's official documentation to confirm tape-and-reel packaging requirements versus bulk supply. Ensure RoHS compliance status aligns with project specifications. Cross-reference the datasheet revision date to validate electrical parameter tolerances before finalizing component selection.

Selection Notes

Select this component when a PNP transistor with 25 V breakdown and 200 mA current capacity is required in a TO-92-3 package. Consider the 100 MHz transition frequency for audio-range signal integrity. Compare against complementary NPN types if push-pull configurations are necessary for the target circuit design.

Part Context

This part belongs to the Central Semiconductor 2N5447 series of general-purpose PNP transistors. These devices are commonly used as complementary pairs to NPN counterparts like the 2N5448 in linear and switching applications. The series is characterized by stable epitaxial planar technology suitable for reliable audio and low-frequency operations.

Replacement Considerations

Publicly confirmed substitutes include the 2N5447 TRE and generic equivalents such as the 2SA733 or BC327, provided pinout and electrical ratings match the TO-92-3 specification.
