BCR48PNH6433XTMA1

Overview

The BCR48PNH6433XTMA1 is a pre-biased bipolar transistor from Infineon Technologies, featuring an integrated NPN/PNP complementary pair. It is housed in a compact SOT-363 (SC-88/6-VSSOP) surface-mount package designed for space-constrained applications. The device includes built-in bias resistors to simplify circuit design and reduce component count. Rated for a maximum collector-emitter voltage of 50V and continuous collector current of 70mA, it operates within a temperature range of -55°C to +150°C. This component is suitable for switching and amplification tasks in digital logic interfaces.

Feature Summary

• Integrates a complementary NPN and PNP bipolar transistor pair with embedded base bias resistors
• Provides simplified switching functionality by reducing external component requirements
• Utilizes a small-footprint SOT-363 surface-mount package for efficient board space utilization

Applications

• Digital logic level shifting and interface circuits
• Switching applications in portable consumer electronics
• General-purpose signal processing in automotive modules

Procurement Notes

Verify the specific suffix H6433XTMA1 against official Infineon documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested quantity aligns with standard factory pack sizes or cut-tape availability. Check current lifecycle status as components may transition to end-of-life phases. Ensure compatibility with automated pick-and-place equipment regarding the SOT-363 package dimensions.

Selection Notes

Select this component when a dual-transistor solution with integrated biasing is required to minimize PCB area. It is appropriate for designs needing both NPN and PNP switching capabilities within a single footprint. Consider the 50V voltage rating and 70mA current limit to ensure they meet the load requirements. Evaluate the thermal performance in the SOT-363 package against the expected power dissipation in the target application environment.

Part Context

This part belongs to Infineon's family of pre-biased transistors, which combine discrete transistors with internal resistors. These devices are engineered to replace multiple discrete components, thereby enhancing reliability and reducing assembly complexity. The BCR48PN variant specifically offers a complementary pair, distinguishing it from single-transistor bias-resistor models. It serves as a standardized solution for high-volume manufacturing where consistent electrical characteristics are critical.
