Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging quantity and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements and lead-free manufacturing standards. Confirm that the SOD-523 package dimensions align with the target PCB footprint and soldering profile limits before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a standard tolerance Zener diode is required in a compact SOD-523 form factor. The 500 mW power rating supports moderate current regulation tasks. Verify that the 27 V breakdown voltage matches the circuit design requirements and that the operating temperature range covers the intended environmental conditions.

Single Zener Diodes Part Context

This part belongs to the MM5ZxxxT1G series of Zener voltage regulators manufactured by onsemi. The series offers a wide breakdown voltage range from 2.4 V to 75 V in a standardized SOD-523 case. These devices are designed for general-purpose voltage regulation and transient suppression in consumer electronics where board space is limited.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOD-523 Zener diodes with a 27 V nominal voltage and 500 mW power rating. Ensure equivalent electrical parameters such as impedance, leakage current, and temperature coefficient are met. Verify mechanical compatibility regarding pinout and body dimensions.

Single Zener Diodes FAQ
