BCX56-10-QF

Overview

The BCX56-10-QF is an NPN medium power transistor from the Nexperia BCX56-Q series, housed in a SOT89 (SC-62) surface-mounted package. It features a collector-emitter voltage of 80 V and a continuous collector current of 1 A, with a peak pulse current capability of 2 A. The device offers three DC current gain selections; the -10 variant specifies a minimum hFE of 63 at IC=150 mA, VCE=2 V, with a maximum of 160. Transition frequency is typically 180 MHz. Qualified under AEC-Q101, it supports junction temperatures up 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 selection options available within the series
• Exposed heatsink design providing excellent thermal and electrical conductivity

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required gain bin, as the BCX56-Q series includes multiple variants with different hFE ranges. Confirm the package type corresponds to the SOT89 footprint requirements for your PCB layout. Ensure the component meets the specific AEC-Q101 qualification standards mandated by your automotive application design specifications before finalizing procurement.

Selection Notes

Select the BCX56-10-Q variant when a controlled DC current gain range between 63 and 160 is required at 150 mA. Consider the exposed pad thermal performance if operating near the 1 A limit or in high ambient temperatures. Verify that the 80 V collector-emitter rating exceeds the maximum circuit voltage spikes. Compare against the standard BCX56 if automotive qualification is not necessary for the target application.

Part Context

This component belongs to the Nexperia BCX56-Q series of NPN medium power transistors designed specifically for robust automotive environments. The series shares the same SOT89 physical package and core electrical ratings but differs in current gain bins (-10, -16, and generic). The Q-series designation indicates adherence to AEC-Q101 stress test qualifications, distinguishing it from general-purpose industrial counterparts.
