BCP54-16TF

Overview

The Nexperia BCP54-16TF is an NPN medium power transistor housed in a SOT223 (SC-73) surface-mount package. It features a collector-emitter voltage of 45 V and a continuous collector current of 1 A, with a peak pulse capability of 2 A. The device offers a DC current gain range of 100 to 250 at VCE = 2 V and IC = 150 mA. Total power dissipation reaches up to 1.8 W on a single-sided FR4 PCB with a 1 cm² collector pad. It operates within a junction temperature range of -55 °C to 150 °C.

Feature Summary

• High collector current capability for both continuous and pulsed operations

Procurement Notes

Verify the specific suffix 'TF' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering code matches the required hFE binning for the -16T variant. Confirm RoHS compliance status and check for any recent revision updates that may affect pinout or thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component when a robust NPN transistor with high current handling is required in a compact SMD form factor. The -16T designation ensures a minimum DC current gain of 100, suitable for applications demanding consistent amplification. Evaluate thermal resistance requirements based on the specific PCB copper area and layer configuration to ensure safe operating area limits are not exceeded during peak load conditions.

Part Context

This part belongs to the BCP54T series, which includes complementary PNP types like the BCP51T. The series provides standardized medium power solutions for general-purpose switching and amplification. The SOT223 package allows for efficient heat dissipation compared to smaller signal transistors, making it a common choice for power stages in consumer electronics and industrial control systems requiring reliable performance.

Replacement Considerations

Direct functional substitutes within the same series include BCP54T and BCP54-10T, though their current gain ranges differ. For identical gain characteristics, verify availability of other manufacturers' equivalents rated for 45V and 1A in SOT223 packages. Always validate thermal performance and pin compatibility before substituting.
