SZMM5Z4690T1G

Single Zener Diodes Overview

The SZMM5Z4690T1G is a single Zener voltage regulator diode from the MM5Z4 series, manufactured by onsemi. It features a nominal reverse Zener voltage of 5.6 V with a tolerance range of 5.32 V to 5.88 V at a test current (IZT) of 50 µA. The device has a steady-state power dissipation rating of 500 mW and operates within a junction temperature range of -55°C to +150°C. It is housed in an SOD-523 surface-mount package (Case 502 Style 1) with dimensions of 1.20 mm x 0.80 mm x 0.60 mm. Maximum reverse leakage current is specified as 10 µA at a reverse voltage of 4 V.

Single Zener Diodes Feature Summary

• Provides voltage regulation protection in space-constrained designs using a compact SOD-523 surface mount package.
• Qualified for automotive applications under AEC-Q101 standards with PPAP capability due to the SZ prefix.
• Features low reverse current characteristics suitable for high-density circuit board applications.

Single Zener Diodes Applications

• Cellular phones
• Handheld portable devices
• High density PC boards

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'T1G' corresponds to the standard 3,000-unit tape and reel packaging configuration. Confirm the presence of the 'SZ' prefix indicates compliance with specific site and control change requirements mandated by AEC-Q101 qualification and PPAP processes. Ensure the component meets RoHS compliance and lead-free specifications as defined in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference or protection level is required in a minimal footprint environment. The SOD-523 package is appropriate for automated assembly processes where board space is limited. Consider the 500 mW power rating and thermal resistance characteristics for steady-state operation. Verify that the 50 µA test current aligns with the low-power requirements of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the MM5Z4xxxTxG and SZMM5Z4xxxTxG series of Zener voltage regulators designed for surface mount technology. The series offers a wide breakdown voltage range from 1.8 V to 43 V in the same small outline package. The SZ prefix specifically denotes parts qualified for automotive use, adhering to stricter manufacturing controls compared to the standard MM5Z variants.

Single Zener Diodes Replacement Considerations

The MM5Z4690T1G serves as the non-automotive equivalent for this component. Both share identical electrical characteristics and physical package dimensions. Substitution requires verifying if the application demands the specific site and control change documentation associated with the SZ prefix.
