BC857BWE6327BTSA1

Overview

The BC857BWE6327BTSA1 is a small signal PNP bipolar junction transistor manufactured by Infineon Technologies. It operates with a maximum collector current of 0.1 A and a collector-emitter voltage rating of 45 V. The device features a minimum DC current gain (hFE) of 200, ensuring reliable amplification in low-power applications. Packaged in the compact SOT-323 surface-mount format, it supports a maximum power dissipation of 250 mW and functions within an operating temperature range from -55 °C to +150 °C.

Feature Summary

• High DC current gain for efficient signal amplification
• Compact SOT-323 surface-mount package design
• Wide thermal operating range up to 150 °C

Applications

• General-purpose switching circuits
• Low-noise amplifier stages
• Signal conditioning modules

Procurement Notes

Verify the specific suffix 'B' confirms the required hFE binning for your circuit design. Confirm the SOT-323 package dimensions match your PCB footprint constraints. Ensure the component meets RoHS compliance standards if required by your manufacturing regulations. Check for automotive qualification status if deploying in vehicle electronics.

Selection Notes

Select this component when a PNP transistor with moderate gain and low current handling is required. Compare against BC857A or BC857C variants based on specific gain requirements. Consider the SOT-323 package size relative to available board space. Evaluate thermal management needs given the 250 mW power dissipation limit.

Part Context

This part belongs to the BC857 series of general-purpose PNP transistors. It shares core electrical characteristics with other members like BC857A and BC857C but differs in gain classification. The series is widely used in consumer electronics and industrial control systems requiring small-signal processing capabilities.

Replacement Considerations

BC857BWE6327XTSA1 serves as a direct functional substitute within the same product family.
