Single Zener Diodes Procurement Notes

Verify the exact part number against official ROHM documentation, as suffixes like 'TR' indicate tape-and-reel packaging which may differ from bulk or cut-tape variants. Confirm RoHS compliance status and specific voltage tolerance requirements (typically 6%) before finalizing procurement orders to ensure alignment with circuit design specifications.

Single Zener Diodes Selection Notes

Select this component when a 1 W power rating and SOD-128 footprint are required for 4.3 V regulation. Ensure the application environment supports the specified operating temperature range up to 150°C. Verify that the 8 Ohm Zener impedance meets the dynamic performance needs of the target circuit compared to lower-power alternatives.

Single Zener Diodes Part Context

This component belongs to the PDZV series of Zener diodes from ROHM Semiconductor. The series is characterized by small plastic packages and high reliability, targeting general voltage regulation tasks. It is classified as a standard-grade product and is explicitly noted as not recommended for use in automotive equipment.
