BCP54E6327

Overview

The Infineon Technologies BCP54E6327 is a single NPN silicon digital transistor housed in an SOT-23-3 surface-mount package. It integrates a base resistor network to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V, a continuous collector current of 1 A, and a minimum DC current gain (hFE) of 100. The device features a typical input resistance of 2.2 kOhms and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates internal base resistors for simplified driver interface
• High current handling capability suitable for power switching applications
• Robust thermal performance with extended operating temperature range

Applications

• General-purpose switching circuits
• Driver stages for relays and solenoids
• Logic-to-analog signal level shifting

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Infineon or authorized distributors before finalizing designs. Confirm that the SOT-23-3 footprint matches your PCB layout requirements. Ensure supply chain stability as availability may fluctuate based on production cycles.

Selection Notes

Select this component when a high-current NPN switch with integrated biasing is required. Compare against standard BJTs to evaluate board space savings from the integrated resistor network. Verify that the 80 V breakdown voltage exceeds the maximum circuit voltage under all operating conditions.

Part Context

This part belongs to Infineon's BCP series of digital transistors, designed for efficient switching in compact electronics. The E6327 suffix typically denotes a specific tape-and-reel packaging configuration used for automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the BCY54 or equivalent NPN digital transistors with matching pinouts and electrical ratings. Ensure any replacement maintains the same SOT-23-3 package dimensions and thermal characteristics.
