Overview
The BCM857BS-QX is a PNP/PNP matched double transistor housed in the SOT363-3 (SC-88) surface-mounted device plastic package. It features fully isolated internal transistors with a collector-emitter voltage of -45 V and a continuous collector current of -100 mA per transistor. The device provides a DC current gain ranging from 200 to 450 at -2 mA, with a transition frequency up to 175 MHz. Total power dissipation reaches 300 mW for the device and 200 mW per transistor at 25 °C ambient temperature. Junction temperatures support operation up to 150 °C.
Feature Summary
- Current gain matching between transistors
- Base-emitter voltage matching within 2 mV
- Drop-in replacement for standard double transistors
Applications
- Current mirror circuits
- Differential amplifier configurations
Procurement Notes
Verify that the specific suffix '-QX' aligns with automotive qualification requirements if intended for such environments. The base BCM857BS datasheet indicates non-automotive status; confirm AEC-Q101 compliance through official Nexperia channels or specific automotive variant documentation before finalizing procurement.
Selection Notes
Select this component when space-constrained designs require matched PNP pairs in an ultra-small SMD footprint. Ensure thermal management accommodates the 300 mW total dissipation limit. Verify that the -45 V rating meets circuit voltage requirements and that the 175 MHz transition frequency satisfies signal bandwidth needs.
Part Context
This part belongs to the BCM857 series of matched double transistors manufactured by Nexperia. It shares electrical characteristics with variants like the BCM857BV and BCM857DS but utilizes the distinct SOT363-3 package. The series is designed for applications requiring precise transistor matching in minimal board space.

FAQ
What is the maximum base-emitter voltage matching tolerance?
The base-emitter voltage matching (VBE1−VBE2) is specified as a maximum of 2 mV under conditions of VCE = -5 V, IC = -2 mA, and Tamb = 25 °C.
How does the junction temperature affect base-emitter voltage?
The base-emitter voltage decreases by approximately 2 mV/K with increasing temperature, while the saturation voltage decreases by about 1.7 mV/K.
Is the BCM857BS-QX automotive qualified?
The provided BCM857BS datasheet states the product is not automotive qualified. Customers should verify if the '-QX' suffix denotes specific automotive testing or consult Nexperia for qualified alternatives like the BCM857BSH-Q.
