Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape and reel specifications. Confirm that the component matches the required tolerance class, as standard variants typically feature ±5% tolerance while tighter tolerances require distinct suffixes. Ensure the procurement specification aligns with the manufacturer's latest product change notifications and environmental compliance data.

Single Zener Diodes Selection Notes

Select this component for designs necessitating 3-watt power handling in a compact surface mount footprint. The integrated metallic tab facilitates efficient heat dissipation compared to standard molded packages. Evaluate the thermal resistance characteristics relative to the PCB layout to ensure the junction temperature remains within the specified operational limits under maximum load conditions.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series utilizes the proprietary Powermite package design, which combines high power capabilities with the convenience of surface mount technology. These devices are engineered to replace larger through-hole components in space-constrained applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other parts from the 1PMT59xx series with identical voltage ratings. Verify mechanical compatibility with the existing mounting pad dimensions due to the unique locking tab geometry. Cross-reference electrical parameters such as dynamic impedance and reverse leakage current to ensure circuit performance stability.
