TZQ5242B-GS08

Single Zener Diodes Overview

The TZQ5242B-GS08 is a single-channel small signal Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 12 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Packaged in the QuadroMELF (SOD-80) surface-mount format, it exhibits a dynamic impedance of 30 Ohms at a test current of 20 mA and a reverse leakage current of less than 1 µA at 9.1 V.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic
• Low reverse current level
• Very high stability
• Low noise

Single Zener Diodes Applications

• Voltage stabilization

Single Zener Diodes Procurement Notes

Verify that the ordering suffix GS08 corresponds to the SOD-80 QuadroMELF package configuration. Confirm compliance with automotive qualification standards such as AEC-Q101 if required for the specific application environment. Ensure thermal management aligns with the specified junction temperature limits during operation.

Single Zener Diodes Selection Notes

Select this component when a stable 12 V reference is needed in a compact surface-mount footprint. The low noise and high stability make it suitable for precision applications. Verify that the 500 mW power rating accommodates the expected operating conditions and ambient temperatures without exceeding thermal limits.

Single Zener Diodes Part Context

This part belongs to the TZQ5221B to TZQ5267B series of small signal Zener diodes from Vishay. The series offers a wide range of nominal voltages from 2.4 V to 75 V. All devices in this family share similar electrical characteristics, including tight tolerances and low reverse currents, packaged in the QuadroMELF SOD-80 format.

Single Zener Diodes Replacement Considerations

Direct substitutes include the TZQ5242B-GS18 variant, which shares identical electrical specifications but utilizes a different reel packaging format.
