Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific tolerance suffixes against official datasheets. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering. Validate package dimensions against PCB footprint specifications.

Single Zener Diodes Selection Notes

Select this component for designs requiring 3-watt power handling in a compact surface mount form factor. Consider the integral heat sink capability for thermal management without external components. Evaluate the tight tolerance availability if precise voltage regulation is critical. Verify compatibility with automated assembly lines due to the unique locking tab design.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener Diodes. These devices are designed to offer higher power capabilities typically found in larger packages while maintaining a small surface mount footprint. The series covers a wide voltage range from 3.3 Volts to 200 Volts.

Single Zener Diodes Replacement Considerations

Equivalent JEDEC registered parts include the 1N5921B series. Surface mount equivalents such as the SMBJ5921Ae3/TR13 provide similar regulation but differ in package type and power ratings.
