1N4763APE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N4763APE3/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 91 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 250 Ohms at a test current of 2.8 mA. It includes RoHS compliance via the 'e3' suffix and tape-and-reel packaging indicated by the 'TR' suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 91 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'P' indicates plastic encapsulation, 'A' denotes 5% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR' specifies tape-and-reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its authorized successor entities. Ensure the component meets JEDEC registration standards for the 1N4763A type number.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener voltage with 5% tolerance is required in a 1 W power rating. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the -65°C to +150°C operating range for environmental suitability. Verify that the 250 Ohm dynamic impedance meets circuit stability requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4728AP through 1N4764AP series of silicon 1-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 to 100 volts. These devices are JEDEC registered and available in both plastic (P suffix) and glass (G suffix) packages, with military screening options available via specific prefixes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMAJ4763A and MLL4763A are available from the same manufacturer family.
