Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives and automotive qualification standards if applicable to the target system environment.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required. Consider the SC-75 package dimensions and thermal resistance characteristics relative to the PCB layout. Evaluate the 100 mA current limit and 50 V voltage rating against the maximum load requirements of the intended application.

Part Context

This part belongs to the BCR135 family of NPN silicon digital transistors. Variants within the series offer different pin configurations and packages, such as SOT-23, TSFP-3, and TSLP-3-4, to accommodate various board space constraints while maintaining consistent electrical performance characteristics.

Replacement Considerations

Direct substitutes include other BCR135 series variants like BCR135F or BCR135L3, provided the package type and pinout are compatible. Cross-brand replacements require careful verification of resistor values, hFE ranges, and thermal specifications.
