Overview
The BCX54-10-Q is an NPN medium power transistor from the Nexperia BCX54-Q series, housed in a SOT89 (SC-62) surface-mounted package. It supports a collector-emitter voltage of 45 V and continuous collector current of 1 A, with peak current up to 2 A. The device offers a DC current gain range of 63 to 160 at IC = 150 mA and VCE = 2 V. It features high power dissipation capability, reaching 0.95 W on standard FR4 PCBs, and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Qualified according to AEC-Q101 for automotive applications
- High collector current capability for both continuous and pulsed operation
- Three distinct current gain selections available within the series
- Exposed die pad design for efficient thermal transfer
Applications
- Linear voltage regulators
- MOSFET drivers
- Low-side switches
- Battery-driven devices

Procurement Notes
Verify the specific ordering suffix matches the required gain bin, as the BCX54-Q series includes variants with different hFE ranges. Confirm that the SOT89 package footprint aligns with the target PCB layout, particularly regarding the exposed collector pad dimensions. Ensure compliance with automotive qualification requirements if deploying in vehicle electronics, as this part is specifically qualified under AEC-Q101 standards.
Selection Notes
Select the BCX54-10-Q variant when a maximum DC current gain of 160 is required, distinguishing it from the standard BCX54-Q which allows gains up to 250. Consider the thermal resistance characteristics based on the intended PCB copper area, as power dissipation capabilities vary significantly between standard footprints and larger heat-sinking pads. Evaluate the 45 V breakdown voltage against circuit operating conditions to ensure adequate safety margins.
Part Context
This component belongs to the BCX54-Q series of NPN medium power transistors designed for robust performance in demanding environments. The series shares the same SOT89 physical package but varies by current gain classification. It serves as a specialized automotive-grade alternative to general-purpose BJT families, offering standardized pinouts and thermal properties suitable for high-reliability switching and amplification tasks.
