1N4734A-TAP

Overview

The Vishay General Semiconductor - Diodes Division 1N4734A-TAP is a silicon planar power Zener diode designed for voltage stabilization and clipping circuits. It features a nominal Zener voltage of 5.6 V with a standard tolerance of ± 5 %. The device operates within a test current range of 3.3 to 76 mA, providing a maximum power dissipation of 1300 mW at thermal equilibrium. It utilizes the DO-41 (DO-204AL) axial through-hole package, supporting a junction temperature up to 175 °C and a storage temperature range from -65 °C to +175 °C.

Feature Summary

• Silicon planar construction optimized for high-power stabilizing and clipping applications
• Standardized Zener voltage tolerance of ± 5 % for consistent performance
• Robust thermal management capabilities with a maximum junction temperature of 175 °C

Applications

• Voltage stabilization in electronic circuits
• Signal clipping applications requiring high power ratings

Procurement Notes

Verify that the specific ordering code matches the required packaging format, as the TAP suffix indicates an ammopack configuration. Confirm compliance requirements against the material categorization definitions provided by the manufacturer. Ensure the selected component aligns with the absolute maximum ratings specified in the datasheet for your intended operating conditions.

Selection Notes

Select this component when a 5.6 V reference or regulation point is required in a through-hole design. Consider the 1300 mW power dissipation capability and the 110 K/W thermal resistance for heat management. Verify that the surge current rating of 810 mA meets the transient protection needs of the target circuit environment.

Part Context

This part belongs to the 1N4728A to 1N4761A series of single Zener diodes manufactured by Vishay Semiconductors. The series covers a broad Zener voltage range from 3.3 V to 75 V, utilizing the standardized DO-41 package. These devices are engineered for general-purpose power regulation tasks across various industrial and commercial electronics platforms.

Replacement Considerations

Cross-reference other manufacturers' 1N4734A equivalents to ensure pinout compatibility and electrical parameter alignment. Verify that substitute components meet the same ± 5 % voltage tolerance and 1300 mW power dissipation specifications.
