1N4751APE3/TR8

Overview

The Microchip Technology 1N4751APE3/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-204AL (DO-41) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 30 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C, features a maximum reverse current of 5 µA at 22.8 V, and includes RoHS compliance indicated by the e3 suffix.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• 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

Applications

• Voltage regulation circuits requiring 30 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the ordering suffix TR8 corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the e3 suffix indicates RoHS compliant annealed matte-tin plating as specified in the datasheet. Ensure the component meets the moisture classification Level 1 requirements without necessitating dry pack storage conditions prior to use.

Selection Notes

Select this component when a 30 V Zener voltage with 5% tolerance is required for power dissipation up to 1.0 watt. Consider the plastic DO-41 package for its lower thermal resistance compared to glass-body options. Verify compatibility with operating temperatures extending to +150°C and ensure the circuit design accommodates the specified dynamic impedance characteristics at the test current.

Part Context

This part belongs to the 1N4728AP thru 1N4764AP series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix denotes plastic construction, while the 'e3' suffix identifies RoHS compliant devices available from the manufacturer.

Replacement Considerations

Consult factory documentation for surface mount equivalents such as SMAJ4751A or MLL4751A. Military screening levels are available via prefixes like MX for JANTX specifications.
