BC857BWE6327

Overview

The BC857BWE6327 is a single PNP silicon bipolar junction transistor manufactured by Infineon Technologies. It operates within a collector-emitter voltage of 45 V and a collector-base voltage of 50 V, with an emitter-base voltage rating of 5 V. The device supports a maximum continuous DC collector current of 100 mA and dissipates up to 330 mW of power. Key electrical characteristics include a transition frequency (fT) of 250 MHz and a DC current gain (hFE) range from 220 to 475. It functions reliably between -65°C and +150°C and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in demanding environments.
• High-frequency operation capability enabled by a 250 MHz transition frequency suitable for signal processing.
• Wide thermal operating range extending from -65°C to +150°C for versatile deployment conditions.

Applications

• General-purpose switching applications in electronic circuits
• Signal amplification in low-power audio or RF stages
• Driver circuits for logic level translation

Procurement Notes

Verify the specific suffix 'WE6327' against official Infineon documentation to confirm packaging details and RoHS compliance status. Confirm availability as this component family may be subject to lifecycle changes. Ensure the ordering part number matches the exact gain bin required for the design specifications before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with high current gain and automotive qualification is required. The 250 MHz bandwidth supports general-purpose switching and amplification tasks. Compare the hFE range of 220 to 475 against circuit requirements to ensure adequate drive capability. Verify that the SOT-23-3 package fits the PCB layout constraints.

Part Context

This part belongs to the BC857 series of small-signal PNP transistors produced by Infineon Technologies. The series is designed for general-purpose use in consumer and industrial electronics. The WE6327 suffix indicates specific tape-and-reel packaging and manufacturing lot tracking. It shares common electrical parameters with other variants in the BC857 family but differs in gain classification and packaging format.

Replacement Considerations

Check for direct substitutes such as BC857BHE6327 or BC857BSE6327 if pinout compatibility is maintained. Verify that alternative parts meet the same AEC-Q100 qualification and hFE specifications. Ensure the replacement maintains the 100 mA current rating and 45 V voltage limits.
