Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or official channels. Confirm RoHS compliance status and check for specific environmental certifications required by your region. Ensure the ordering suffix matches the exact tolerance and packaging specifications needed for your design. Review the latest product change notifications for any updates regarding this discontinued series.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V Zener reference with ±2% precision is required in a compact surface-mount form factor. The 3.0 W power rating supports higher current loads compared to standard axial equivalents. The Powermite package facilitates efficient thermal dissipation via its locking tab. Verify that the operating environment remains within the specified -55°C to +150°C temperature range for reliable performance.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener diodes. These devices are equivalent to the JEDEC registered 1N5913B through 1N5956B series but offer enhanced power handling capabilities. The series utilizes the Powermite surface mount package to provide lower thermal resistance and improved mechanical stability for modern PCB designs.

Single Zener Diodes Replacement Considerations

Equivalent JEDEC registered parts include the 1N5921B series. For identical electrical characteristics in a plastic axial package, consider the 1N5921BP variant. Military screening levels may be available under different nomenclature referencing MIL-PRF-19500 standards.
