1N4763CPE3/TR8

Overview

The Microsemi Corporation 1N4763CPE3/TR8 is a silicon unidirectional Zener diode housed in a DO-204AL (DO-41) plastic axial-lead package. It provides voltage regulation at a nominal Zener voltage of 91 V with a tight tolerance of plus or minus 2%, indicated by the 'C' suffix. The device dissipates up to 1.0 watt of power and operates within a temperature range of -65°C to +150°C. It features RoHS compliance via the 'e3' suffix and is supplied in tape and reel packaging, denoted by the 'TR' suffix.

Feature Summary

• Provides precise voltage regulation with a 2% tolerance on nominal Zener voltage
• Features flexible axial-lead mounting terminals for through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation over a broad operating current and temperature range
• Surge protection circuits utilizing steady-state power capabilities
• General purpose electronic equipment requiring stable reference voltages

Procurement Notes

Verify that the ordering suffixes match the required specifications: 'P' indicates plastic construction, 'C' confirms the 2% voltage tolerance, 'e3' denotes RoHS compliance, and 'TR' specifies tape and reel packaging. Confirm the manufacturer origin as Microsemi Corporation or its successor entity. Ensure the component meets the JEDEC registration requirements for the 1N4763A series before procurement.

Selection Notes

Select this component when a 91 V Zener voltage with high precision is required. The 2% tolerance makes it suitable for applications demanding tighter voltage control than standard 5% or 10% variants. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the 1.0 W power dissipation rating and the specific thermal derating curves for high-temperature environments.

Part Context

This part belongs to the popular 1N4728AP thru 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers an extensive voltage selection from 3.3 to 100 volts. While the base 1N4763A has a 5% tolerance, the 'C' suffix designates a tighter 2% tolerance variant. These devices are JEDEC registered and available in various military screening levels with different prefixes.

Replacement Considerations

Surface mount equivalents are available as SMAJ4763A and MLL4763A. For glass-body options, the 1N4763AG series provides hermetic-sealed qualities and higher rated temperatures. Other tolerance variants include 1N4763A (5%) and 1N4763D (1%). Verify compatibility regarding thermal resistance differences between plastic and glass packages.
