1N4762ADO41E3

Single Zener Diodes Overview

The Microsemi Corporation 1N4762ADO41E3 is a single silicon Zener diode designed for through-hole mounting in the DO-204AL (DO-41) package. It features a nominal breakdown voltage of 82 V with a ±5% tolerance and a maximum power dissipation of 1 W. The device is RoHS compliant and lead-free, utilizing an e3 suffix to indicate tin-plated terminals. It operates within a temperature range defined by standard JEDEC specifications for this component class.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 82 V with tight manufacturing tolerances
• Hermetically sealed glass encapsulation ensures reliability in harsh environments
• RoHS compliant construction supports environmentally conscious assembly processes

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in power supply inputs
• Clamping applications in signal conditioning networks

Single Zener Diodes Procurement Notes

Verify that the specific order includes the ADO41E3 suffix to confirm the DO-204AL plastic body variant with RoHS compliance. Ensure procurement matches the required tolerance grade, as other variants may offer different percentage accuracies or non-compliant packaging options. Cross-reference the manufacturer's current datasheet to confirm terminal plating and screening levels before finalizing purchase orders.

Single Zener Diodes Selection Notes

Select this component when a robust, hermetically sealed Zener diode is required for high-reliability applications. The DO-204AL package offers mechanical stability for through-hole assembly. Consider the 82 V breakdown point and 1 W power rating against circuit load requirements. Verify thermal management needs if operating near maximum power dissipation limits in enclosed spaces.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of 1-watt Zener diodes manufactured by Microsemi. The series provides extensive voltage selection from 3.3 to 100 V. The 'A' prefix typically denotes military screening levels, while the 'e3' suffix indicates lead-free, RoHS-compliant terminals. This specific model represents a standardized voltage point within the broader family of precision voltage regulators.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4762AG for hermetic glass versions and 1N4762AP for plastic body variants. Check tolerance grades, as some equivalents may offer 10% or 2% accuracy instead of the standard 5%. Ensure replacement packages match the DO-204AL footprint for direct board integration without redesigning solder pads.
