Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel configuration. Confirm the manufacturer designation aligns with current Microchip Technology specifications rather than legacy Microsemi documentation. Ensure the component meets the necessary environmental compliance standards for the intended deployment environment before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when circuit requirements demand a 51 V reference point with significant power dissipation capabilities in a compact form factor. The Powermite package offers superior thermal performance compared to smaller surface mount alternatives. Consider the tight tolerance availability if stricter voltage regulation limits are required beyond the standard specification.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3-watt Zener diodes manufactured by Microchip Technology. The series utilizes the proprietary Powermite surface mount technology to deliver robust power handling in a small footprint. These devices are engineered to replace larger through-hole components while maintaining equivalent electrical performance characteristics.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1PMT5942 variants from different manufacturers such as ON Semiconductor or Microsemi, provided they match the DO-216AA package dimensions and 51 V rating.
