BCP53

Overview

The EVVO BCP53 is a PNP silicon small-signal transistor housed in an SOT-223 surface-mount package. It features four terminals with a dual gull-wing configuration and a rectangular plastic epoxy body. The collector connects to the case for thermal efficiency. Key electrical ratings include a maximum collector-emitter voltage of -80 V, continuous collector current of 1.5 A, and power dissipation of 5 W at 25°C. The device exhibits a minimum DC current gain (hFE) of 25 at 5 mA and 150 mA, with a transition frequency of 100 MHz.

Feature Summary

• Designed specifically for audio frequency driver and output stages
• Provides high collector current capability for power handling
• Ensures low collector-emitter saturation voltage for efficiency

Applications

• Audio frequency driver circuits
• Audio output stages
• General-purpose switching applications

Procurement Notes

Verify the specific manufacturer designation as EVVO corresponds to the provided datasheet specifications. Confirm the SOT-223 pinout matches the Base-Collector-Emitter-Collector arrangement. Ensure compliance with RoHS directives if required by the target application environment. Cross-reference absolute maximum ratings against circuit operating conditions to prevent thermal or electrical overstress during procurement validation.

Selection Notes

Select this component when a PNP transistor with 80 V breakdown and 1.5 A current capacity is required in a compact SOT-223 footprint. Consider the complementary NPN types BCP54, BCP55, and BCP56 for push-pull configurations. Evaluate the thermal resistance and power dissipation limits relative to the expected load current and ambient temperature conditions to ensure reliable operation within the specified junction temperature range.

Part Context

This device belongs to the BCP51/BCP52/BCP53 series of PNP medium power transistors. The series shares identical physical packaging and pinout structures while differing primarily in their collector-base and collector-emitter voltage ratings. The BCP53 variant offers a balanced rating profile suitable for general-purpose amplification tasks where moderate voltage blocking is necessary alongside significant current drive capabilities.

Replacement Considerations

Complementary counterparts include the BCP54, BCP55, and BCP56 NPN transistors. Verify that substitute parts match the SOT-223 package dimensions and terminal alignment. Ensure replacement devices meet or exceed the -80 V collector-emitter voltage and 1.5 A current requirements.
