BC860C-QR

Overview

The BC860C-QR is a PNP general-purpose transistor manufactured by Nexperia, designed for low-current and low-voltage applications. It operates within a collector-emitter voltage (VCEO) of 45 V and supports a maximum continuous collector current of 100 mA. The device features a transition frequency (fT) of 100 MHz and a DC current gain (hFE) range of 420 to 800 at IC = 2 mA. It is housed in an SOT-323 (SC-70) surface-mount package with a power dissipation rating of 200 mW. The component is qualified under the AEC-Q101 standard for automotive use and functions reliably across a temperature range of -55°C to +150°C.

Feature Summary

• AEC-Q101 qualified for automotive electronics reliability standards
• Low noise performance suitable for audio-frequency equipment
• Small SOT-323 surface-mount plastic package design

Applications

• Low noise stages in tape recorders
• Hi-fi amplifiers and other audio-frequency equipment
• General purpose switching and amplification circuits

Procurement Notes

Verify that the suffix QR confirms AEC-Q101 automotive qualification status through official Nexperia documentation. Confirm the specific hFE binning (C grade: 420-800) matches circuit requirements. Ensure the SOT-323 footprint aligns with PCB layout specifications. Cross-reference the manufacturer part number against authorized distributor lists to guarantee authenticity and traceability.

Selection Notes

Select this component when automotive reliability and low-noise characteristics are required for small-signal PNP applications. The BC860C-QR serves as the PNP complement to the BC849CW NPN transistor within the same family. Consider its 100 mA current limit and 45 V voltage rating for appropriate biasing conditions. Verify thermal management capabilities given the 200 mW power dissipation constraint in the compact SOT-323 package.

Part Context

This device belongs to the Nexperia BC8xx series of general-purpose transistors, specifically designed for low-power signal processing tasks. It shares the SOT-323 form factor with related components like the BC859W and BC860W. The 'QR' suffix typically denotes automotive-grade qualification and specific packaging configurations defined by the manufacturer's internal coding standards.

Replacement Considerations

The BC860C is the standard commercial equivalent. For pin-compatible replacements, consider the BC857C or BC860C from other manufacturers, ensuring hFE ranges and VCEO ratings match. Verify if alternative parts meet AEC-Q101 requirements if automotive qualification is mandatory.
