1N4761APE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N4761APE3/TR8 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation with a nominal Zener voltage of 75 V and a standard tolerance of ±10%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance indicated by the 'e3' suffix.

Single Zener Diodes Feature Summary

• Provides voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard installation
• Constructed with a void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against overvoltage conditions in electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance and packaging configuration. Confirm RoHS compliance status if restricted material usage is mandated. Ensure the component meets the necessary military screening levels if applicable, as prefixes indicate different qualification standards. Cross-reference datasheet electrical characteristics against circuit requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 75 V regulation point is required with a 10% tolerance. Consider the plastic package construction for lower thermal resistance compared to glass-body options. Evaluate the maximum power dissipation and derating curves to ensure operation remains within safe junction temperatures under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N4728A to 1N4764A series of 1.0-watt Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix designates plastic construction, while the 'e3' suffix indicates RoHS compliant plating. Surface mount equivalents are available in SMAJ and MLL packages.

Single Zener Diodes Replacement Considerations

Surface mount equivalents include SMAJ4761A and MLL4761A. Glass-body options exist for the same JEDEC number but differ in thermal resistance. Military screening variants require specific prefix identifiers such as MQ or MX.
