Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level, as standard versions differ from the C-suffix variant. Confirm the package designation aligns with the intended PCB footprint. Ensure compliance with RoHS directives if applicable to the target market. Check for any product change notifications or discontinuance alerts prior to finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a compact surface mount solution is required for precise voltage regulation. The tight ±2% tolerance makes it suitable for applications demanding accurate reference voltages. Consider the thermal resistance and power dissipation capabilities relative to the available board space and cooling methods. Verify that the forward voltage characteristics meet the circuit requirements under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener diodes. The series offers a wide selection of Zener voltages ranging from 3.3 Volts to 200 Volts. These devices are designed to provide power-handling capabilities typically found in larger packages while maintaining a low-profile surface mount form factor.

Single Zener Diodes Replacement Considerations
