BCP55-16-QF

Overview

The BCP55-16-QF is an NPN medium power transistor from the Nexperia BCP55-Q series, housed in a small SOT223 (SC-73) Surface-Mounted Device plastic package. It features a collector-emitter voltage of 60 V and a continuous collector current of 1 A, with a peak pulse current capability of 2 A. The device offers three current gain selections; the -16 variant provides a DC current gain range of 100 to 250 at VCE = 2 V and IC = 150 mA. Qualified according to AEC-Q101, it supports high power dissipation up to 1.35 W on a 6 cm² copper pad and operates within a junction temperature range of -55 °C to 150 °C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required current gain bin, as the -16 designation indicates a specific hFE range. Confirm the package type is SOT223 (SC-73) and that the component carries the Q-series marking for automotive qualification. Ensure design parameters align with the absolute maximum ratings provided in the official datasheet before finalizing procurement specifications.

Selection Notes

Select this component when an NPN transistor with 60 V blocking capability and 1 A continuous current handling is required in a compact SMD form factor. The -16 gain bin is suitable for applications needing a minimum hFE of 100 at moderate currents. Consider the thermal resistance values and PCB copper area requirements to ensure adequate heat dissipation for the intended power load.

Part Context

This part belongs to the BCP55-Q series of NPN medium power transistors manufactured by Nexperia. The series includes variants with different current gain bins (-Q, -10-Q, -16-Q) and their PNP complements (BCP52-Q series). All members share the same SOT223 package and electrical limits but differ in amplification characteristics to suit various circuit design needs.

Replacement Considerations

The BCP52-16-Q is the PNP complement within the same series. Other BCP55-Q variants may be considered if different gain ranges are acceptable, provided the package and voltage/current ratings remain compatible.
