TZQ5254B-GS18

Single Zener Diodes Overview

The TZQ5254B-GS18 is a single small signal Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device operates within a test current range of 1.7 to 20 mA and has a maximum power dissipation of 500 mW. It utilizes the QuadroMELF (SOD-80) surface-mount package, supports junction temperatures up to 175 °C, and meets AEC-Q101 automotive qualification standards.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise regulation
• Low reverse current level ensuring minimal leakage
• 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 suffix GS18 corresponds to the required taped reel quantity of 10,000 units per 13-inch reel. Confirm that the QuadroMELF SOD-80 package dimensions align with the target PCB footprint. Ensure compliance with RoHS3 specifications and check for any regional technical support requirements via authorized channels.

Single Zener Diodes Selection Notes

Select this component when a stable 27 V reference is required in space-constrained designs. The SOD-80 package offers a compact solution suitable for automated surface-mount assembly. Consider the thermal impedance characteristics and the positive temperature coefficient inherent to Zener voltages above approximately 6 V when designing for wide operating temperature ranges.

Single Zener Diodes Part Context

This part belongs to the TZQ5221B through TZQ5267B series of small signal Zener diodes. The series provides a comprehensive range of nominal voltages from 2.4 V to 75 V. All devices share identical physical packaging and general electrical characteristics, differing primarily in their specific Zener voltage ratings and associated test currents.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay family include other TZQ52xxB-GS18 variants with different voltage ratings. Cross-manufacturer replacements must match the SOD-80 footprint, 500 mW power rating, and ±5% tolerance while verifying equivalent dynamic resistance and leakage current specifications.
