Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm pinout compatibility and material composition. Confirm end-of-life status or obsolescence notices prior to final design approval. Ensure that the selected packaging format matches the intended automated assembly process requirements.

Selection Notes

Select this component when a compact NPN transistor with moderate current handling and high-speed switching capabilities is required. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the thermal constraints imposed by the 330 mW power dissipation limit in enclosed designs.

Part Context

This part belongs to the BCX70 series of bipolar junction transistors designed for audio frequency and switching applications. The series provides a balance between current capacity and speed in a standard three-terminal surface-mount footprint, widely used in consumer and industrial electronics.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure any replacement maintains identical pin configuration and meets or exceeds the 45 V voltage and 100 mA current ratings.
