BC847B-QVL

Overview

The BC847B-QVL is an NPN general-purpose transistor from Nexperia, designed for surface-mount applications. It operates with a collector-emitter voltage of 45V and a continuous collector current of 100mA. The device features a DC current gain (hFE) range of 200 to 450 at 2mA and 5V. It is housed in the SOT363 package, which measures 1.6mm x 1.25mm x 0.55mm. The component is qualified according to AEC-Q101 standards for automotive use and supports a maximum junction temperature of 150°C.

Feature Summary

• Automotive qualification compliant with AEC-Q101 standards
• Ultra-thin SOT363 package for high-density board space reduction
• High DC current gain selection for efficient switching performance

Applications

• General-purpose switching in automotive electronics
• Signal amplification in compact consumer devices
• Battery management systems requiring small form factors

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and availability status. Check for end-of-life notices or recommended new design warnings. Ensure compatibility with automated pick-and-place equipment due to the thin profile. Confirm RoHS compliance and moisture sensitivity levels prior to assembly.

Selection Notes

Select this component when automotive reliability and minimal footprint are critical. The BC847B-QVL offers a balance of moderate current handling and high gain in a tiny package. Compare against standard SOT23 variants if higher power dissipation is required. Consider thermal constraints given the small surface area of the SOT363 housing.

Part Context

This part belongs to the BC847 family of NPN transistors, widely used in low-power signal processing. The 'Q' suffix indicates automotive qualification, while 'VL' specifies the SOT363 tape-and-reel packaging configuration. It serves as a compact alternative to larger discrete transistors in modern miniaturized circuits.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified NPN transistors in SOT363 packages. Verify pinout compatibility and electrical parameters such as Vceo and hFE ranges before substitution.
