Procurement Notes

This component has reached end-of-life status and is officially obsolete. Procurement should focus on verifying stock availability through authorized distributors or surplus suppliers. Ensure that any acquired units are genuine Infineon products with intact markings. Validate datasheet revisions if available, as legacy components may have specific handling requirements due to their discontinued status.

Selection Notes

Select this part only for designs requiring an 80V, 1A NPN transistor in a SOT-89 footprint. Consider the obsolete status when planning long-term production runs. Evaluate alternative modern equivalents from Infineon's current portfolio if supply chain stability is critical. Verify that the thermal performance of the SOT-89 package meets the system's heat dissipation needs under maximum load conditions.

Part Context

The BCX56 series represents Infineon's line of high-power NPN transistors designed for audio and general-purpose applications. The E6327HTSA1 suffix indicates specific tape-and-reel packaging and manufacturing lot details. As part of the broader BJT family, these devices offer reliable performance for medium-to-high power tasks where compact surface-mount solutions are preferred over through-hole alternatives.
