Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm RoHS compliance status via the specific datasheet. Check for end-of-life notifications as discontinuation may affect long-term supply. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when a PNP transistor with 1 A continuous current and 80 V breakdown voltage is required in an SOT-89-4 package. Consider the 125 MHz transition frequency for audio band operations. Verify thermal management capabilities for 1 W power dissipation in the target enclosure design.

Part Context

This part is part of the BCX53 family of high-current, low-voltage transistors designed for audio and general-purpose switching. It shares the SOT-89-4 form factor with other variants in the series but differs in voltage ratings and polarity compared to NPN counterparts like the BCX52.

Replacement Considerations

BCX53 E6327HTSA1 is a confirmed equivalent part number.
