ZMY18-GS18

Single Zener Diodes Overview

The ZMY18-GS18 is a single silicon planar power Zener diode manufactured by Vishay General Semiconductor. It features an 18 V nominal Zener voltage with a ±5% tolerance and a maximum power dissipation of 1 W. The device utilizes a DO-213AB (MELF) glass package for surface mount installation. Key electrical characteristics include a maximum dynamic impedance of 11 Ohms and a reverse leakage current of 500 nA at 14 V. It operates within a temperature range of -65°C to 175°C and holds AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• High power rating of 1 W for stabilizing and clipping circuits
• Automotive grade reliability with AEC-Q101 qualification
• Compact MELF glass package suitable for automated mounting

Single Zener Diodes Applications

• Voltage stabilization in automotive electronic systems
• Signal clipping and waveform shaping circuits
• Reference voltage generation in industrial control modules

Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 corresponds to the required reel packaging configuration, as other suffixes may indicate different tape-and-reel dimensions or quantities. Confirm that the DO-213AB footprint matches the target PCB design. Ensure compliance with RoHS 2002/95/EC directives if environmental regulations apply to the final assembly. Cross-reference the AEC-Q101 certification status for automotive supply chain requirements.

Single Zener Diodes Selection Notes

Select this component when a 1 W power rating is necessary for high-current Zener applications requiring robust thermal performance. The DO-213AB package offers a compact alternative to through-hole options while maintaining high power handling. Consider the 11 Ohm dynamic impedance for applications requiring moderate regulation precision. The wide operating temperature range supports deployment in harsh automotive and industrial environments where standard commercial parts may fail.

Single Zener Diodes Part Context

This part belongs to the ZMY series of silicon planar power Zener diodes from Vishay. The series covers a wide voltage range up to 100 V, graded according to international E24 standards. These components are designed for high-power applications and are available in both glass MELF and DO41 cases. The ZMY series is widely used in power supplies and protection circuits due to its reliability and standardized voltage grading.
