BCR 191F E6327

Overview

The Infineon Technologies BCR 191F E6327 is a PNP Silicon Digital Transistor designed for surface mount applications in the SOT-23-3 package. It features an integrated bias resistor network with R1 and R2 both specified at 22 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 50 and a transition frequency (fT) of 200 MHz. Power dissipation is rated at 250 mW, with an operating temperature range spanning from -65°C to +150°C.

Feature Summary

• Integrates dual bias resistors (R1=22kΩ, R2=22kΩ) to simplify circuit design
• Provides high-speed switching capabilities suitable for interface and driver circuits
• Offers compact surface-mount packaging for efficient board space utilization

Applications

• Switching circuits
• Inverter applications
• Interface circuits
• Driver circuits

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity upon receipt as the component utilizes small outline packaging. Ensure storage conditions maintain moisture sensitivity levels per manufacturer guidelines prior to soldering. Cross-reference ordering codes with official Infineon documentation to avoid substitution errors during procurement.

Selection Notes

Select this component when a pre-biased PNP transistor is required for logic interfacing or low-power switching tasks. The integrated resistor network reduces external component count compared to discrete solutions. Evaluate thermal management requirements given the 250 mW power dissipation limit in the SOT-23-3 form factor. Consider the 200 MHz transition frequency for high-speed digital signal processing applications.
