BCX54-16,115

Overview

The BCX54-16,115 is an NPN medium power transistor in a SOT89 (SC-62) surface-mount package. It features a collector-emitter voltage of 45 V and a continuous collector current of 1 A. The device offers a peak collector current of 2 A and a DC current gain range of 100 to 250 at IC = 150 mA. Total power dissipation reaches 1.35 W on a 6 cm² collector pad. Transition frequency is 180 MHz, with junction temperatures up to 150 °C.

Feature Summary

High collector current capability for both continuous and pulsed operation
Three distinct current gain selections available within the series
Exposed die pad design in SOT89 package for efficient heat transfer

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required gain bin. Confirm that the non-automotive qualification status aligns with the target application environment. Ensure thermal management designs account for the specified power dissipation limits under actual operating conditions.

Selection Notes

Select this variant when a 45 V rating and 1 A current capacity are required in a compact SMD form factor. The -16 suffix indicates a specific hFE range suitable for moderate amplification needs. Evaluate PCB copper area requirements to achieve the maximum rated power dissipation.

Part Context

This component belongs to the BCX54 series of NPN transistors manufactured by Nexperia. The series provides multiple gain options (-10, -16) alongside the standard version. All variants share identical electrical ratings and the SOT89 package structure.
