BCR48PNE6433BTMA1

Overview

The BCR48PNE6433BTMA1 is a PNP silicon digital transistor manufactured by Infineon Technologies, designed for switching applications. It integrates a single PNP bipolar junction transistor with internal biasing resistors within an SOT-23-3 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 47 kOhms and a minimum DC current gain (hFE) of 70. It operates reliably across a temperature range from -65°C to +150°C and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrated biasing network simplifies circuit design by reducing external component count
• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• General-purpose switching in automotive electronic control units
• Load switching for low-power peripheral devices
• Interface circuits between microcontrollers and analog loads

Procurement Notes

Verify the exact ordering suffix against official Infineon documentation to confirm pinout compatibility and specific tape-and-reel packaging requirements. Confirm end-of-life status or obsolescence notices prior to finalizing procurement plans, as availability may be restricted for discontinued series components.

Selection Notes

Select this component when a PNP configuration with high input impedance is required for logic-level interfacing. Ensure the 47 kOhm base resistor value aligns with the driving source capabilities. Verify that the 100 mA current rating exceeds the maximum load current under all operating conditions to prevent device failure.

Part Context

This part belongs to the Infineon BCR series of digital transistors, which combine bipolar transistors with integrated resistors. The BCR48 variant specifically denotes a PNP structure with a 47 kOhm input resistor ratio. These components are widely used to replace discrete resistor-transistor networks in space-constrained PCB layouts.

Replacement Considerations

Consult official cross-reference lists for direct substitutes such as other BCR48 variants with different suffixes if packaging differs. Generic PNP digital transistors with matching 50V/100mA ratings and SOT-23-3 packages may serve as functional alternatives if automotive qualification is not mandatory.
