BCX56-16,147

Overview

The BCX56-16,147 is an NPN medium power transistor from the Nexperia BCX56 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, with a peak pulse current capability of 2 A. The device features a DC current gain (hFE) range of 100 to 250 at IC = 150 mA and VCE = 2 V. Thermal resistance from junction to ambient varies based on PCB footprint, ranging from 250 K/W for standard footprints to 93 K/W with a 6 cm² collector pad.

Feature Summary

• High collector current capability for both continuous and pulsed operations
• Three distinct current gain selections available within the series
• Exposed heatsink design providing high power dissipation capability

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 that the component meets all required environmental standards and marking codes for your assembly process. Ensure compatibility with the designated SOT89 footprint dimensions during procurement planning.

Selection Notes

Select this component when an NPN transistor with 80 V breakdown and 1 A current handling is required in a compact SMD form factor. The BCX56-16 variant is appropriate for designs needing a guaranteed minimum hFE of 100. Consider thermal management requirements based on the specific PCB copper area allocated for the collector pad.

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 BCX56-10 and BCX56-16, all sharing the same electrical ratings and physical SOT89 package dimensions. The series is designed for general-purpose switching and amplification applications.

Replacement Considerations

Direct substitutes within the same family include BCX56-10 for lower gain requirements or generic BCX56 for unspecified gain. Cross-family replacements require matching the 80 V VCEO, 1 A IC rating, and SOT89 package outline while verifying pinout compatibility.
