ZM4738A-GS18

Single Zener Diodes Overview

The ZM4738A-GS18 is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 8.2 V with a standard tolerance of ±5%. The device operates within a junction temperature range up to 175 °C and dissipates up to 1 W of power. Packaged in the glass MELF (DO-213AB) format, it is supplied in tape-and-reel quantities of 5,000 units per reel.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for stable operation in stabilizing and clipping circuits
• Provides high power dissipation capability suitable for demanding applications
• Encased in a robust glass MELF (DO-213AB) package designed for surface-mount assembly

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the specific GS18 suffix corresponds to the 5,000-unit tape-and-reel packaging configuration as defined in the official ordering information. Confirm compliance with RoHS3 standards and ensure the application environment remains within the specified thermal equilibrium conditions to maintain rated power dissipation.

Single Zener Diodes Selection Notes

Select this component when an 8.2 V reference with ±5% tolerance is required in a compact surface-mount form factor. Ensure the circuit design accommodates the 1 W power rating and verify that the operating ambient temperature allows for adequate heat dissipation without exceeding the maximum junction temperature limit.

Single Zener Diodes Part Context

This part belongs to the ZM4728A through ZM4761A series of power Zener diodes from Vishay. These devices are functionally equivalent to the 1N4728A through 1N4761A series but utilize the DO-213AB MELF package instead of the traditional DO-41 axial leaded case, offering a more compact solution for modern PCB layouts.

Single Zener Diodes Replacement Considerations

Direct equivalents include other manufacturers' 8.2 V Zener diodes in the DO-213AB package. Cross-reference with the 1N4738A series for legacy compatibility, ensuring the replacement supports the required 1 W power dissipation and ±5% voltage tolerance.
