TZQ5266B-GS08

Single Zener Diodes Overview

The TZQ5266B-GS08 is a single Zener diode from the Vishay TZQ5221B to TZQ5267B series, housed in a QuadroMELF (SOD-80) package. It features a nominal Zener voltage of 68 V with a ±5% tolerance and a maximum power dissipation of 500 mW. The device operates within a junction temperature range of -65 °C to +175 °C and exhibits a low reverse leakage current of less than 0.1 µA at 25 °C.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise regulation
• Low reverse current level ensuring minimal standby loss
• High stability and low noise performance
• Tight voltage tolerance of ±5%

Single Zener Diodes Applications

• Voltage stabilization

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging details. Confirm that the QuadroMELF SOD-80 package dimensions align with the target PCB footprint. Ensure thermal management strategies account for the specified power dissipation limits under actual operating conditions.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 68 V is required in a compact surface-mount form factor. Consider the negative temperature coefficient characteristics below 5.6 V and positive coefficients above 6 V; this 68 V unit falls in the positive region. Evaluate the dynamic resistance requirements against the circuit's load regulation needs.

Single Zener Diodes Part Context

This part belongs to the Vishay General Semiconductor - Diodes Division small signal Zener diode portfolio. The broader TZQ5221B to TZQ5267B series offers various voltage options ranging from 2.4 V to 75 V, all sharing similar physical dimensions and electrical characteristics tailored for precision applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOD-80 packaged Zener diodes rated at 68 V with 500 mW power dissipation. Verify that alternative parts meet the same ±5% tolerance and thermal specifications before substitution.
