MM5Z18VT1

Single Zener Diodes Overview

The MM5Z18VT1 is a Zener voltage regulator diode from the MM5Z2V4T1 series, manufactured by onsemi. It is housed in an SOD-523 (CASE 502) surface-mount package with dimensions of 1.20 mm x 0.80 mm and a body height of 0.7 mm. The device provides a nominal reverse Zener voltage of 18 V with a tolerance range of 16.8 V to 19.1 V at a test current of 2 mA. It features a steady-state power dissipation rating of 100 mW at 25°C ambient temperature. Electrical characteristics include a maximum Zener impedance of 45 Ohms at the test current and a leakage current of 50 µA at a reverse voltage of 12.6 V. The component operates within a junction and storage temperature range of -65°C to +150°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as tape and reel specifications. Ensure the requested part number matches the exact electrical parameters required for the application. Cross-reference the manufacturer's latest datasheet revision to confirm compliance with current mechanical and environmental standards before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount solution is required for low-power voltage regulation. The SOD-523 package is suitable for applications where board space is limited. Consider the 100 mW power dissipation limit and the specific Zener voltage tolerance when designing circuits that require precise voltage reference or protection levels.

Single Zener Diodes Part Context

This component belongs to the MM5Z2V4T1 series of Zener voltage regulators produced by onsemi. The series offers a standard breakdown voltage range from 2.4 V to 75 V in a single surface-mount form factor. These devices are engineered to provide reliable voltage regulation while maintaining a minimal footprint, making them ideal for modern electronic designs requiring high component density.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include MM5Z16VT1 and MM5Z20VT1, which share identical packaging and general characteristics but differ in nominal Zener voltage. Verify that alternative components meet the specific voltage and impedance requirements of the circuit design.
