ZMY68-GS18

Single Zener Diodes Overview

The ZMY68-GS18 is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 68 V with a tolerance of ±5% and a maximum power dissipation of 1 W at 25 °C ambient temperature. The component utilizes a DO-213AB (MELF) glass package, providing an isolated case connection. It operates within a junction temperature range up to 175 °C and meets RoHS 2002/95/EC standards.

Single Zener Diodes Feature Summary

• Silicon planar construction for high power rating applications
• Glass MELF package with isolated cathode band marking
• Zener voltages graded according to international E 24 standard

Single Zener Diodes Applications

• Voltage stabilization circuits
• Signal clipping circuits
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 corresponds to the required packaging format, typically 5 k per 13-inch reel. Confirm compliance with RoHS directives and check for AEC-Q101 automotive qualification if applicable to the target environment. Ensure the DO-213AB package dimensions match the PCB footprint requirements.

Single Zener Diodes Selection Notes

Select this component when a 1 W power rating and 68 V regulation are required in a surface-mountable glass MELF package. Consider the ±5% tolerance and low noise characteristics suitable for precision applications. Evaluate thermal management needs given the 175 °C maximum operating temperature limit.

Single Zener Diodes Part Context

This part belongs to the ZMY series of silicon planar power Zener diodes from Vishay. The series offers various voltage ratings graded to the E 24 standard, available in both DO-213AB and DO-41 packages. The ZMY series is designed for stabilizing and clipping circuits requiring higher power handling capabilities compared to standard small-signal diodes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 68 V, 1 W Zener diodes in DO-213AB packages. Verify electrical parameters such as impedance and leakage current match the original specifications before substitution.
