BCX56-16,135

Overview

The BCX56-16,135 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-emitter voltage of 80 V and a continuous collector current of 1 A, with a peak pulse current capability of 2 A. The device features a DC current gain range of 100 to 250 at a collector current of 150 mA and a transition frequency of 180 MHz. Total power dissipation reaches up to 1.35 W when mounted on a PCB with a 6 cm² collector pad.

Feature Summary

• High collector current capability for both continuous and pulsed operation
• Three distinct current gain selections available within the series
• High power dissipation capacity facilitated by 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 official Nexperia documentation to confirm packaging format and reel specifications. Confirm RoHS compliance status and ensure the component meets the required automotive or industrial qualification standards before integration into final designs.

Selection Notes

Select this component for applications requiring high current handling in a compact surface-mount footprint. The BCX56-16 variant provides a guaranteed minimum current gain of 100, suitable for precise amplification tasks. Evaluate thermal resistance requirements based on the intended PCB copper area to ensure adequate heat dissipation during operation.

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 ranges, such as the BCX56-10 and standard BCX56. All share the same SOT89 package and electrical ratings, differing primarily in their hFE binning for specific circuit gain requirements.

Replacement Considerations

Direct substitutes include BCX56-10 and BCX56 from the same Nexperia series, provided the lower gain specifications are acceptable for the application.
