TZX4V3A-TAP

Single Zener Diodes Overview

The TZX4V3A-TAP is a small signal Zener diode from the Vishay TZX-Series, housed in a DO-35 (DO-204AH) axial leaded package. It features a nominal Zener voltage range of 4 to 4.2 V at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Key electrical characteristics include a reverse leakage current of 1 µA maximum at 1.5 V and a dynamic resistance of 100 Ω maximum.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise voltage regulation
• Low reverse current level ensuring minimal leakage
• Very high stability under varying operating conditions
• Low noise performance suitable for sensitive circuits

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TAP' corresponds to the taped reel packaging format containing 10,000 units per ammopack. Confirm that the minimum order quantity aligns with the box requirement of 30,000 units. Ensure the component matches the DO-35 package dimensions and lead specifications required by the assembly process.

Single Zener Diodes Selection Notes

Select this part when a nominal 4.2 V reference is required with tight tolerance limits defined by the 'A' suffix. Consider the 500 mW power rating and thermal resistance of 300 K/W for heat dissipation requirements. Evaluate the low reverse leakage and dynamic impedance against circuit sensitivity needs compared to other series options.

Single Zener Diodes Part Context

This component belongs to the Vishay TZX-Series of small signal Zener diodes. The series offers a wide voltage range from 2.4 V to 36 V across various tolerance suffixes. The TZX4V3A variant specifically targets applications requiring stable voltage references near 4 V with strict leakage and stability constraints.

Single Zener Diodes Replacement Considerations

Cross-reference with other TZX-series variants like TZX4V3B or TZX4V3C if different voltage tolerances are acceptable. Verify compatibility with DO-35 packages from other manufacturers if sourcing alternatives.
