BZT55B4V3-GS08

Single Zener Diodes Overview

The BZT55B4V3-GS08 is a single unidirectional silicon Zener diode from the Vishay BZT55 series, designed for voltage stabilization. It features a nominal Zener voltage of 4.3 V with a tight tolerance range of 4.22 V to 4.38 V at a test current of 5 mA. The device operates within a maximum power dissipation of 500 mW and supports junction temperatures up to 175 °C. Packaged in the QuadroMELF SOD-80 surface-mount format, it offers low reverse leakage and high stability.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Over-voltage protection

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix GS08 corresponds to the required tape and reel packaging configuration (2500 units per 7-inch reel). Confirm that the component meets RoHS compliance standards and material categorization requirements as defined by the manufacturer's documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a nominal 4.3 V reference with ±2% tolerance is required. Ensure the application circuit can handle the 500 mW power dissipation limit and operates within the specified -65 °C to +175 °C temperature range. Verify compatibility with the SOD-80 footprint during PCB layout design.

Single Zener Diodes Part Context

This part belongs to the BZT55 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V, utilizing the QuadroMELF SOD-80 package. These components are engineered for general-purpose voltage regulation applications requiring high reliability and stable electrical characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZT55B4V3-GS18, which shares identical electrical specifications but utilizes different packaging quantities (10,000 units per 13-inch reel). Cross-brand replacements must match the 4.3 V nominal voltage, 500 mW power rating, and SOD-80 package dimensions.
