TLZ5V1-GS18

Single Zener Diodes Overview

The TLZ5V1-GS18 is a single small signal Zener diode from Vishay Semiconductors, housed in a MiniMELF (SOD-80) surface-mount package. It provides a nominal Zener voltage range of 4.94 V to 5.2 V at a test current of 20 mA. The device features a maximum reverse leakage current of 1 µA and a dynamic resistance of 20 Ω at the test current. It supports a total power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise regulation
• Low reverse current level ensuring minimal standby loss
• Very high stability with low noise performance

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 against the official datasheet to confirm the 10,000 units per reel tape configuration. Ensure that the required Zener voltage tolerance falls within the B-marking range specified in the electrical characteristics table. Confirm compliance requirements such as RoHS status directly from the manufacturer's documentation before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 5 V is required in a compact SMD footprint. The MiniMELF package offers thermal reliability suitable for automated assembly processes. Consider the 20 mA test current requirement for biasing circuit design and ensure the operating environment stays within the specified temperature limits for optimal voltage stability.

Single Zener Diodes Part Context

This part belongs to the TLZ-Series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.4 V to 56 V, utilizing the MiniMELF (SOD-80) package. The GS18 ordering code specifically denotes the standard reel packaging format containing 10,000 units per reel.

Single Zener Diodes Replacement Considerations

Cross-reference other TLZ-series variants or equivalent SOD-80 Zener diodes from other manufacturers. Verify that any substitute matches the 5.1 V nominal voltage, 500 mW power rating, and physical dimensions of the MiniMELF package.
