BCR191E6327HTSA1

Overview

The BCR191E6327HTSA1 is a pre-biased PNP silicon digital transistor manufactured by Infineon Technologies. It integrates a single NPN bias resistor into a compact SOT-23-3 surface-mount package to simplify circuit design and reduce component count. The device is designed for switching applications, offering a power dissipation rating of 200mW. It is halogen-free compliant and supports automated assembly processes.

Feature Summary

• Integrates an internal NPN bias resistor with the PNP transistor
• Simplifies circuit layout by reducing external component requirements
• Optimized for high-speed switching operations

Applications

• General purpose switching circuits
• Interface logic level translation
• Driver stages for low-power loads

Procurement Notes

Verify end-of-life status before finalizing designs, as production may be discontinued. Confirm RoHS compliance and halogen-free specifications against current datasheets. Ensure SOT-23-3 footprint compatibility during PCB layout validation. Check for alternative sources if long-term supply stability is required.

Selection Notes

Select this component when a compact solution for driving PNP switches is needed without external base resistors. Consider the 200mW power dissipation limit for thermal management. Evaluate the integrated bias configuration against discrete resistor alternatives for space-constrained designs requiring simplified bill of materials.
