Single Zener Diodes Procurement Notes

Verify the component origin carefully as the datasheet originates from Microsemi, which has undergone corporate restructuring. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compatibility with the intended thermal management strategy given the 30°C/W junction-to-tab resistance. Cross-reference the manufacturer documentation to validate current production status and availability constraints.

Single Zener Diodes Selection Notes

Select this component when a 3-watt power handling capability is necessary within a compact surface mount footprint. The design is particularly suitable for applications demanding low reverse leakage and high ESD immunity. Consider the thermal resistance specifications when designing the PCB layout to ensure effective heat dissipation through the metallic bottom and locking tab interface.

Single Zener Diodes Part Context

This device belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener Diodes. These components are engineered to provide significant power handling in smaller packages compared to traditional through-hole alternatives. The series offers a wide range of Zener voltages from 3.3 to 200 Volts, catering to diverse voltage regulation requirements across various electronic systems.

Single Zener Diodes Replacement Considerations
