BZX55B4V3-TAP

Single Zener Diodes Overview

The BZX55B4V3-TAP is a single silicon Zener diode from the Vishay BZX55 series, housed in an axial DO-35 (DO-204AH) glass package. It provides a nominal Zener voltage of 4.3 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 1 µA at 1 V and a dynamic impedance of less than 90 Ω. It features a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise voltage regulation
• Low reverse current level ensuring minimal power loss
• 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 that the ordering suffix '-TAP' corresponds to the specific Ammo Pack packaging configuration containing 10,000 units per pack. Confirm compliance with RoHS3 directives and ensure the component meets AEC-Q101 automotive qualification standards if required by the design specifications.

Single Zener Diodes Selection Notes

Select this part when a tighter voltage tolerance of ±2% is required compared to standard ±5% variants. Ensure the circuit design accommodates the low test current of 5 mA and the specific thermal resistance characteristics of the DO-35 package for optimal performance.

Single Zener Diodes Part Context

This component belongs to the BZX55 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of nominal voltages from 2.4 V to 75 V in the same compact axial glass package, providing designers with standardized options for various voltage regulation needs.

Single Zener Diodes Replacement Considerations

Equivalent parts within the BZX55 series include BZX55B4V3-TR for reel packaging or BZX55C4V3-TAP if a wider ±5% tolerance is acceptable.
