BCR141E6327HTSA1

Overview

The BCR141E6327HTSA1 is an NPN silicon digital transistor from Infineon Technologies, housed in a surface-mount SOT-23 (SC74) package. It integrates a single transistor with built-in bias resistors configured as R1=22kΩ and R2=22kΩ. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Total power dissipation is rated at 250mW, with a junction temperature limit of 150°C. Electrical characteristics include a DC current gain (hFE) minimum of 50, a transition frequency (fT) of 130MHz, and a collector-emitter saturation voltage of 0.3V.

• Designed for switching, inversion, interface, and driver circuits

Applications

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

Procurement Notes

Verify the component authenticity by checking the laser marking code 'WD' against the official datasheet specifications. Confirm that the physical package matches the SC74 outline dimensions provided in the manufacturer's documentation. Ensure compliance with RoHS standards and confirm the specific ordering suffix aligns with the required tape-and-reel packaging configuration.

Selection Notes

Select this component when a compact NPN digital solution with integrated biasing is required for low-voltage logic interfacing. The 22kΩ input resistor value provides a specific base drive characteristic suitable for standard logic levels. Consider the thermal resistance limits and the 100mA current rating to ensure the operating conditions remain within the specified safe operating area.

Part Context

This part belongs to the BCR141 series of NPN silicon digital transistors manufactured by Infineon Technologies. The series includes variants with different pin configurations and packages, such as the dual-transistor SOT363 and SOT323 options. The E6327HTSA1 suffix specifically denotes the single-transistor version packaged in the SOT-23 form factor.

Replacement Considerations

Direct replacements must match the NPN polarity, 50V VCEO rating, and 22kΩ/22kΩ resistor ratio. Verify that any substitute component meets the same AEC-Q101 qualification requirements if used in automotive contexts. Package compatibility should be confirmed before substitution.
