BZT55C39-GS18

Single Zener Diodes Overview

The BZT55C39-GS18 is a single silicon Zener diode from the Vishay BZT55 series, housed in a QuadroMELF (SOD-80) surface-mount package. It provides a nominal Zener voltage of 39 V with a tolerance range of 37 V to 41 V. The device operates at a test current of 2.5 mA and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 0.5 µA at 30 V, a dynamic resistance of less than 90 Ω, and a temperature coefficient ranging from 0.04 %/K at 25 °C to 0.12 %/K at 150 °C.

Single Zener Diodes Feature Summary

• Provides very sharp reverse characteristic for precise voltage regulation
• Features low reverse current level and very high stability
• Designed for low noise operation

Single Zener Diodes Applications

• Voltage stabilization

Single Zener Diodes Procurement Notes

Verify component authenticity by checking the manufacturer marking on the SOD-80 package against official datasheet specifications. Confirm that the ordering code suffix matches the GS18 taped reel configuration. Ensure compliance with RoHS directives and material categorization requirements as defined by the manufacturer before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 39 V reference is required in a compact surface-mount footprint. The BZT55C39 variant offers tighter voltage tolerance compared to standard C-series parts. Consider the thermal impedance characteristics and operating temperature limits when designing circuits that require continuous power dissipation near the maximum rating.

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 in the QuadroMELF SOD-80 package. These components are designed for general-purpose voltage regulation applications requiring high stability and low noise performance in a miniature form factor.
