BCR185SH6327XTSA1

Overview

The BCR185SH6327XTSA1 is a PNP digital transistor manufactured by Infineon Technologies, designed for surface-mount applications in the SOT-323 package. It integrates a single PNP bipolar junction transistor with an internal base resistor to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 70. It operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 250 mW.

Feature Summary

• Integrated base resistor simplifies driver interface requirements
• High thermal stability with extended operating temperature range
• Compact SOT-323 surface-mount packaging for space-constrained designs

Applications

• General-purpose switching applications
• Driver circuits for logic level translation
• Load switching in portable electronic devices

Procurement Notes

Verify the specific suffix H6327XTSA1 against official Infineon documentation to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure compatibility with automated pick-and-place equipment regarding the SOT-323 footprint dimensions. Cross-reference the part number with the manufacturer's latest lifecycle notifications to confirm availability status prior to finalizing procurement plans.

Selection Notes

Select this component when a compact PNP switch with integrated biasing is required. The 10 kOhm internal resistor value should be evaluated against the driving source impedance to ensure adequate base current for saturation. Verify that the 100 mA collector current limit meets the load requirements and that the 250 mW power dissipation capability is sufficient for the expected thermal environment.

Part Context

This part belongs to the BCR185 series of digital transistors from Infineon Technologies. The series typically includes variants with different resistor values or transistor polarities. The BCR185SH6327XTSA1 specifically denotes the PNP configuration with the standard 10 kOhm base resistor in the SOT-323 package, optimized for general-purpose low-power switching tasks.

Replacement Considerations

Potential substitutes include other PNP digital transistors in SOT-323 packages with similar VCEO and Ic ratings, such as those from ON Semiconductor or STMicroelectronics. Verify pinout compatibility and resistor tolerance before substitution.
