Overview
The Nexperia BCX54,115 is an NPN medium power transistor housed in a SOT89 (SC-62) surface-mount package. It supports a collector-emitter voltage of 45 V and a continuous collector current of 1 A. The device features a DC current gain range of 63 to 250 at VCE = 2 V and IC = 150 mA. Thermal resistance from junction to ambient is 250 K/W on a standard FR4 PCB footprint. The transition frequency is typically 180 MHz.
Feature Summary
- High collector current capability for both continuous and pulsed operation
- Three distinct current gain selections available within the series
- High power dissipation capability with exposed die pad for thermal transfer
Applications
- Linear voltage regulators
- MOSFET drivers
- Low-side switches
- Battery-driven devices
- Power management circuits
- Amplifiers
Procurement Notes
Verify that the specific part number matches the required current gain bin, as the BCX54 series includes variants like BCX54-10 and BCX54-16 with different hFE ranges. Confirm the package type is SOT89 and check for any automotive qualification requirements, as this specific revision indicates non-automotive qualification status.
Selection Notes
Select the BCX54,115 when a 45 V NPN transistor with 1 A current handling is needed in a compact SMD form factor. Ensure the application operates within the specified junction temperature limits and utilizes adequate PCB copper area for heat dissipation to maintain performance under load conditions.
Part Context
This component belongs to the BCX54 series of NPN medium power transistors manufactured by Nexperia. The series is designed for general-purpose switching and amplification tasks. The SOT89 package provides a balance between power handling and small footprint, suitable for dense PCB layouts.
