MM3Z13VST1G

Single Zener Diodes Overview

The MM3Z13VST1G is a Zener voltage regulator from the MM3ZxxxST1G series, packaged in an SOD-323 surface mount case. It features a steady-state power rating of 500 mW and tight tolerance breakdown voltage. The device operates within a junction temperature range of -65°C to +150°C. Electrical characteristics at 25°C include a reverse Zener voltage (VZ) range of 12.91 V to 13.49 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance (ZZK) is 160 Ω at IZ = 0.5 mA, with a maximum reverse leakage current (IR) of 0.1 µA at VR = 8.0 V.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required package quantity and tape-and-reel specifications. Confirm that the component meets RoHS compliance and lead-free requirements as stated in the datasheet. Ensure the application environment stays within the specified thermal derating curves and maximum case soldering temperatures to maintain reliability.

Single Zener Diodes Selection Notes

Select this component when space is limited due to its small SOD-323 outline dimensions. Consider the tight tolerance requirement if precise voltage reference stability is critical. Evaluate the 500 mW power dissipation capability against the expected operating conditions and PCB copper area available for heat sinking.

Single Zener Diodes Part Context

This part belongs to the MM3ZxxxST1G series of Zener diodes manufactured by onsemi. The series utilizes a void-free, transfer-molded plastic case with corrosion-resistant finishes. The SZ prefix variant indicates qualification for automotive applications requiring unique site and control change requirements under AEC-Q101 standards.

Single Zener Diodes Replacement Considerations

Other members of the MM3ZxxxST1G series may serve as substitutes if the Zener voltage differs but other parameters align. Verify that any replacement maintains the same SOD-323 footprint and pinout configuration.
