2N5447 PBFREE

Overview

The 2N5447 PBFREE is a PNP bipolar junction transistor manufactured by Central Semiconductor Corp. It features an epitaxial planar silicon construction housed in a TO-92-3 through-hole package. The device supports a maximum collector-emitter voltage of 25 V and a continuous collector current of 200 mA. Its transition frequency is rated at 100 MHz, with a power dissipation capacity of 625 mW.

Feature Summary

• Epitaxial planar silicon PNP construction
• Designed for audio frequency applications
• Through-hole TO-92-3 lead-free packaging

Applications

• Audio amplifier circuits
• General-purpose switching
• Signal processing stages

Procurement Notes

Verify the specific ordering suffix to ensure compliance with environmental standards. The 'PBFREE' designation indicates lead-free plating as per manufacturer specifications. Confirm that the TO-92-3 package style matches the intended PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for low-power PNP switching or amplification tasks requiring a standard TO-92 footprint. Ensure the application voltage remains within the 25 V limit and current stays below 200 mA. Consider thermal management for the 625 mW dissipation rating in enclosed designs.

Part Context

This part belongs to the Central Semiconductor 2N5447 series of general-purpose PNP transistors. It serves as a complementary device often paired with NPN counterparts in audio and signal circuits. The series utilizes epoxy molding for mechanical protection and electrical isolation.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes from other manufacturers. Verify that alternative parts match the 25 V voltage rating, 200 mA current capability, and TO-92-3 package dimensions to ensure functional equivalence.
