Single Zener Diodes Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Confirm authenticity through official MCC documentation or authorized channel certificates, as end-of-life status increases risk of counterfeit or obsolete inventory.

Single Zener Diodes Selection Notes

Designers requiring this specific 39 V Zener characteristic must evaluate alternative components due to discontinuation. Consider equivalent voltage ratings and power dissipation capabilities in compatible SMB packages. Verify that replacement parts meet the same AEC-Q101 automotive qualification requirements if used in vehicle systems.

Single Zener Diodes Part Context

The SMBJ5939BHE3-TP belongs to the SMBJ59xxB series of Zener diodes from Micro Commercial Components. This series provides stable voltage regulation in compact surface-mount formats suitable for space-constrained PCB layouts. The HE3 suffix indicates halogen-free construction compliant with environmental regulations.
