Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tolerance specification. Confirm the package type aligns with the PCB footprint design. Ensure the manufacturer documentation is current to validate electrical characteristics and mechanical dimensions before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 180 V Zener voltage with ±2% tolerance is required in a surface mount configuration. The 3.0 W power rating and integrated heat sink make it suitable for high-power density designs. Verify compatibility with automated assembly processes due to the specific Powermite package geometry.

Single Zener Diodes Part Context

This part belongs to the 1PMT59xx series of 3-watt Zener diodes manufactured by Microchip Technology. The series utilizes the Powermite surface mount package, which offers advantages over traditional through-hole packages regarding size and thermal efficiency. The 'C' suffix specifically denotes the tighter manufacturing tolerance compared to standard variants.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 180 V Zener diodes in the DO-216AA package with similar power ratings. Verify pinout compatibility and thermal resistance values. Consider alternative manufacturers offering equivalent specifications if supply constraints exist.
