BZT55C51-GS08

Single Zener Diodes Overview

The BZT55C51-GS08 is a small signal Zener diode from Vishay General Semiconductor, featuring a nominal Zener voltage of 51 V with a tolerance range of 48 V to 54 V. It operates at a test current of 2.5 mA and exhibits low reverse leakage current of less than 0.1 µA. The device provides dynamic resistance values under 125 Ω at the test current and up to 700 Ω at lower currents. Packaged in a QuadroMELF (SOD-80) housing, it supports a maximum power dissipation of 500 mW and functions within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix GS08 corresponds to the 2500 units per 7-inch reel configuration as documented in the official Vishay datasheet. Confirm that the QuadroMELF SOD-80 package dimensions and soldering conditions align with your PCB footprint and reflow profile requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 51 V reference is required with tight tolerance specifications. The low leakage current and sharp breakdown characteristic make it suitable for precision applications. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specific thermal resistance characteristics of the SOD-80 package under your intended ambient temperature conditions.

Single Zener Diodes Part Context

This part belongs to the BZT55-Series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of nominal voltages from 2.4 V to 75 V. The BZT55C51 variant specifically targets the 51 V segment, providing consistent electrical characteristics typical of the C-series tolerance band within the broader product line.

Single Zener Diodes Replacement Considerations

Cross-reference with other BZT55-series variants or equivalent Melf-style Zener diodes from other manufacturers if supply constraints exist. Verify that any substitute matches the 51 V nominal voltage, 500 mW power rating, and SOD-80 package dimensions to ensure mechanical and electrical compatibility.
