1N4760PE3/TR8

Overview

The Microchip Technology 1N4760PE3/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 at a nominal Zener voltage of 68 V with 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 150 Ohms at a test current of 3.7 mA. It includes RoHS compliance via the 'e3' suffix and tape-and-reel packaging indicated by the 'TR8' suffix.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 68 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm package type and compliance status. The 'e3' suffix indicates RoHS compliance, while 'TR8' denotes tape-and-reel packaging. Confirm that the manufacturer designation aligns with current corporate structures following acquisitions. Ensure the component meets the required JEDEC registration standards for your specific application environment.

Selection Notes

Select this component when a 68 V Zener voltage with ±5% tolerance is required in a 1-watt power dissipation class. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the operating temperature range and dynamic impedance characteristics for precision regulation needs. Verify compatibility with existing PCB footprints designed for the DO-204AL form factor.

Part Context

This part belongs to the widely used 1N47xxA series of silicon Zener diodes, originally standardized by JEDEC. The series covers a voltage range from 3.3 V to 100 V. The 'P' suffix designates the plastic encapsulated construction, distinguishing it from glass-body variants. This specific iteration represents the modern RoHS-compliant version of the classic military-grade regulated diode.

Replacement Considerations

Direct replacements include other manufacturers' 1N4760A or 1N4760AP equivalents in the DO-41 package. Ensure substitute parts match the 68 V nominal voltage, 1 W power rating, and ±5% tolerance specifications. Verify that alternative sources provide similar dynamic impedance and thermal resistance values.
