1N4734A-T

Single Zener Diodes Overview

The Vishay 1N4734A-T 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, depending on the specific voltage rating. It provides a maximum power dissipation of 1300 mW at thermal equilibrium and supports a junction temperature up to 175 °C. Packaged in the DO-41 (DO-204AL) through-hole format, it offers low reverse leakage current and high surge current capability.

Single Zener Diodes Feature Summary

• Silicon planar construction optimized for stabilizing and clipping applications

Single Zener Diodes Procurement Notes

Verify the exact ordering code suffix against the manufacturer's official documentation to confirm packaging type. The datasheet specifies distinct codes for taped units per reel and ammopack configurations. Ensure the selected variant matches the required minimum order quantity and reel specifications for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with ±5% tolerance is required in a through-hole package. Confirm that the 1300 mW power dissipation rating aligns with the ambient temperature and thermal resistance constraints of the target design. Validate that the DO-41 package dimensions fit the available PCB space.

Single Zener Diodes Part Context

This part belongs to the 1N4728A to 1N4761A series of silicon planar power Zener diodes manufactured by Vishay Semiconductors. The series covers a wide nominal Zener voltage range from 3.3 V to 75 V. All devices in this family share the same DO-41 package outline and fundamental electrical characteristics, differing primarily in their specific voltage ratings and corresponding test currents.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the JEDEC registered 1N4734A designation. Verify that substitute components meet the identical 5.6 V nominal voltage, ±5% tolerance, and 1300 mW power dissipation requirements in the DO-41 package.
