BCX56-10,135

Overview

The BCX56-10,135 is an NPN medium power transistor from the Nexperia BCX56 series, housed in a SOT89 (SC-62) surface-mounted plastic package. It supports a collector current of 1 A and a peak collector current of 2 A. The device features a collector-emitter voltage rating of 80 V and a collector-base voltage of 100 V. The DC current gain (hFE) ranges from 63 to 160 at VCE = 2 V and IC = 150 mA. Total power dissipation reaches 0.50 W in free air and up to 1.35 W with a 6 cm² collector pad on an FR4 PCB.

Feature Summary

• High collector current capability for both continuous and pulsed operation
• Three distinct current gain selections available within the series
• High power dissipation capability with exposed heatsink design

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component matches the required hFE binning specifications for the intended circuit design before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring an NPN transistor with high current handling and moderate voltage ratings. The SOT89 package provides thermal advantages over standard small-signal packages. Consider the specific hFE range requirements of the application to choose between the different gain variants offered in the BCX56 series.

Part Context

This part belongs to the BCX56 series of NPN medium power transistors manufactured by Nexperia. The series includes variants with different current gain characteristics, specifically the BCX56, BCX56-10, and BCX56-16. All variants share the same physical package and electrical limits but differ in their amplification factors.

Replacement Considerations

Compatible substitutes include the BCX56 and BCX56-16 from the same Nexperia series, provided the specific DC current gain requirements align with the application needs. Other general-purpose NPN transistors in the SOT89 package may serve as alternatives if electrical parameters are verified to be sufficient.
