BCR 179L3 E6327

Overview

The BCR 179L3 E6327 is a PNP silicon digital transistor from the BCR179 series, manufactured by Infineon Technologies. It features an integrated bias resistor with a nominal value of 10 kΩ (range 7–13 kΩ). The device operates with a collector-emitter voltage (VCEO) of 50 V and a maximum collector current (IC) of 100 mA. Electrical characteristics include a DC current gain (hFE) ranging from 120 to 630 at IC = 5 mA, and a transition frequency (fT) of 150 MHz at IC = 10 mA. Total power dissipation is rated at 250 mW for the L3 package variant. The component utilizes a TSLP-3-4 surface-mount package.

Feature Summary

• Integrated base bias resistor simplifies circuit design by eliminating external components.
• High DC current gain supports efficient switching performance in logic applications.
• Transition frequency of 150 MHz enables operation in high-speed digital circuits.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's product compliance database prior to procurement. Ensure that the intended application does not involve life-support systems without explicit written approval from Infineon Technologies.

Selection Notes

Select this component when a PNP digital transistor with a 10 kΩ internal resistor is required. Verify that the 50 V collector-emitter voltage rating meets the circuit requirements. Consider the thermal resistance characteristics of the TSLP-3-4 package for heat dissipation calculations in the final assembly.

Part Context

This part belongs to the BCR179 family of PNP silicon digital transistors. Variants such as BCR179F and BCR179T share similar electrical characteristics but differ in packaging, specifically SC75 and TSFP-3 respectively. The E6327 suffix denotes the specific packaging and reel configuration for mass production.

Replacement Considerations

BCR179F and BCR179T are electrically equivalent alternatives within the same series, differing primarily in package geometry (SC75 and TSFP-3). Verify pin compatibility and thermal resistance values before substituting these variants in existing designs.
