BCR 112F E6327

Overview

The BCR 112F E6327 is an NPN silicon digital transistor manufactured by Infineon Technologies. It features a single configuration housed in a surface-mount SOT-23-3 package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device incorporates an integrated base resistor with a typical value of 4.7 kOhms and a typical resistance ratio of 0.47. Minimum DC current gain (hFE) is specified at 20, with a transition frequency of 140 MHz and power dissipation rated at 200 mW. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Integrated base resistor simplifies circuit design by eliminating external biasing components.
• High switching speed supported by a 140 MHz transition frequency for efficient signal processing.
• Robust thermal performance allows operation up to 150°C junction temperature.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for low-current loads such as LEDs or relays.
• Logic level translation between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix 'E6327' against official Infineon documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Check for any active obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when a compact NPN digital switch with moderate current handling is required. Ensure the 100 mA collector current limit meets load requirements. Verify that the 50 V voltage rating exceeds the maximum circuit potential. Compare the 4.7 kOhm internal resistance against drive source capabilities to ensure adequate base current.

Part Context

This part belongs to Infineon's BCR series of pre-biased digital transistors. These components integrate bipolar junction transistors with built-in resistors to reduce board space and assembly costs. The E6327 suffix typically denotes specific packaging and ordering variants within the broader product family.

Replacement Considerations

Consult official Infineon cross-reference guides for verified substitutes. Generic equivalents may differ in internal resistance values or hFE characteristics. Validate pinout compatibility and thermal resistance before implementing alternative parts.
