1N4763A

Single Zener Diodes Overview

The SMC Diode Solutions 1N4763A is a silicon unidirectional voltage regulator diode designed for through-hole mounting. It features a DO-41 (DO-204AL) plastic axial leaded package with two terminals. The device provides a nominal Zener voltage of 91 V and supports a maximum power dissipation of 1 W. Standard voltage tolerance is plus or minus 5% for the 'A' suffix variant. It operates within a temperature range extending up to 150 °C.

Single Zener Diodes Feature Summary

• Maintains stable voltage regulation across broad operating current and temperature ranges
• Constructed using silicon planar technology for reliable performance
• Available in standard voltage tolerances including plus or minus 5%

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as SMC Diode Solutions may source this component from other manufacturers. Confirm RoHS compliance status and lead-free availability, as original specifications indicate non-compliance. Ensure the package matches the required DO-41 form factor and that the 91 V rating aligns with circuit requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a 91 V reference is required in a through-hole design. Consider the 1 W power rating for thermal management. Verify if surface mount equivalents like SMAJ4763A are suitable for space-constrained layouts. Check for military screening options if high reliability is necessary.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of power Zener diodes, widely used for general-purpose voltage regulation. The series offers extensive voltage selection from 3.3 V to 100 V. Variants exist with different tolerances and screening levels, such as JAN or JANS grades, often indicated by specific prefixes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents include SMAJ4763A and MLL4763A. Other manufacturers produce compatible parts under the same 1N4763A designation, but electrical parameters and package dimensions should be verified against the specific datasheet.
