BCX53-10,135

Overview

The BCX53-10,135 is a PNP medium power transistor from the Nexperia BCX53 series, housed in a SOT89 (SC-62) surface-mount package. It supports a collector-emitter voltage of -80 V and a continuous collector current of -1 A. The device offers three DC current gain selections; the BCX53-10 variant provides a minimum hFE of 100 at IC = -150 mA. Key electrical parameters include a peak collector current of -2 A, total power dissipation up to 1.35 W on a 6 cm² pad, and a transition frequency of 145 MHz.

Feature Summary

• High current capability with exposed heatsink for thermal conductivity
• Three distinct current gain selections available within the series
• Qualified according to AEC-Q101 automotive standards

Applications

• Linear voltage regulators
• High-side switches
• Battery-driven devices
• Power management circuits
• MOSFET drivers
• Amplifiers

Procurement Notes

Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the selected part number retains AEC-Q101 qualification status, as revision history indicates some variants may have removed this automotive qualification. Ensure design compliance with absolute maximum ratings to prevent permanent damage.

Selection Notes

Select the BCX53-10 variant when a guaranteed minimum DC current gain of 100 is required at a collector current of -150 mA. Consider the SOT89 package dimensions and thermal resistance values when designing heat dissipation strategies. Verify compatibility with intended switching frequencies against the specified transition frequency limits.

Part Context

This component belongs to the BCX53 series of PNP medium power transistors manufactured by Nexperia. The series includes variants such as BCX53, BCX53-10, and BCX53-16, differentiated primarily by their DC current gain ranges. All variants share identical voltage ratings, current capabilities, and physical package specifications.

Replacement Considerations

Consult official Nexperia documentation for qualified alternative part numbers or complements. Verify pinout compatibility and thermal characteristics when substituting components in existing designs.
