BCR142E6327HTSA1

Overview

The BCR142E6327HTSA1 is an NPN silicon digital transistor from the BCR142 series, manufactured by Infineon Technologies. It integrates a single NPN transistor with built-in bias resistors (R1=22kΩ, R2=47kΩ) in a compact SOT-23 surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a total power dissipation of 200 mW at a case temperature up to 102°C. The device features a minimum DC current gain (hFE) of 70 at IC=5mA and VCE=5V, with a transition frequency (fT) of 150 MHz. It operates within a junction temperature range of -65°C to +150°C and complies with AEC-Q101 qualification standards.

Feature Summary

• Integrated bias network consisting of a 22kΩ input resistor and a 47kΩ base-emitter resistor simplifies circuit design by reducing component count.
• Qualified according to AEC-Q101 standards for automotive applications, ensuring reliability under varying thermal conditions.
• Pb-free packaging compliant with RoHS directives, supporting environmentally conscious manufacturing processes.

Applications

• Switching circuits requiring high-speed digital control
• Inverter stages in logic gate implementations
• Interface circuits between microcontrollers and peripheral loads
• Driver circuits for low-power relay or LED activation

Procurement Notes

Verify the specific ordering suffix E6327HTSA1 against official Infineon documentation to confirm the exact tape-and-reel quantity and packaging variant. Confirm that the requested part matches the SOT-23 package type rather than the SOT-323 variant (BCR142W). Ensure compliance with AEC-Q101 requirements if deploying in automotive environments. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.

Selection Notes

Select this component when a pre-biased NPN transistor is required for space-constrained designs. The fixed resistor ratio of approximately 0.47 suits standard logic interface applications. Consider the 200 mW power dissipation limit at elevated case temperatures when designing thermal management strategies. Compare against the BCR142W variant if a smaller SOT-323 footprint is necessary, noting the difference in thermal resistance characteristics.

Part Context

This component belongs to the BCR142 series of NPN silicon digital transistors. It shares the same internal circuit topology as other members of the family but is distinguished by its specific ordering code and SOT-23 packaging. The series is designed to replace discrete resistor-transistor combinations, offering a standardized solution for digital switching tasks across consumer and industrial electronics.
