BCR 146L3 E6327

Overview

The BCR 146L3 E6327 is an NPN silicon digital transistor manufactured by Infineon Technologies, designed for switching, inverter, interface, and driver circuits. It integrates a bias resistor network consisting of R1 (47 kΩ) and R2 (22 kΩ). The device operates with a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 70 mA. Total power dissipation reaches 250 mW at a case temperature up to 135°C. Electrical characteristics include a DC current gain (hFE) minimum of 50 at IC = 5 mA, transition frequency (fT) of 150 MHz, and input resistor tolerance ranging from 32 kΩ to 62 kΩ.

Feature Summary

• High-speed switching capability supported by a 150 MHz transition frequency.
• Robust thermal performance allowing 250 mW power dissipation under specified conditions.

Applications

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

Procurement Notes

Verify the specific ordering suffix L3 corresponds to the SC75 package type during procurement. Confirm component authenticity through official Infineon channels or authorized distributors. Check for RoHS compliance status as indicated in the datasheet documentation. Ensure storage and handling procedures adhere to moisture sensitivity levels defined for surface-mount devices.

Selection Notes

Select this component when a compact NPN digital solution with integrated biasing is required. The SC75 package offers specific thermal resistance characteristics compared to SOT-23 alternatives. Consider the 70 mA collector current limit for load requirements. Verify that the 50 V breakdown voltage meets the circuit's maximum operating voltage constraints.

Part Context

This part belongs to the BCR146 family of NPN silicon digital transistors. Variants within the family share identical electrical specifications but differ in physical packaging, including SOT-23, TSFP-3, TSLP-3-4, SC75, and SOT323. The L3 suffix specifically identifies the SC75 package configuration used in this product code.

Replacement Considerations

Direct replacements must match the NPN polarity, 50 V rating, 70 mA current capacity, and integrated 47 kΩ/22 kΩ resistor values. Package compatibility requires verifying pinout alignment between SC75 and alternative packages like SOT-23 if mechanical changes are permissible.
