1N4760E3/TR13

Overview

The Microchip Technology 1N4760E3/TR13 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. 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 plastic DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA, a maximum reverse current of 13 µA at 2000 V, and a steady-state power dissipation of 1.0 watts.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard circuit 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 68 V reference
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the ordering suffix TR13 corresponds to tape and reel packaging as specified in the datasheet. Confirm RoHS compliance status via the e3 suffix designation. Ensure the required voltage tolerance aligns with the standard A suffix specification. Check for any specific military screening prefixes if higher reliability levels are needed for the application environment.

Selection Notes

Select this component when a 68 V Zener voltage with 5% tolerance is required for 1-watt power dissipation. Consider the plastic DO-41 package for its lower thermal resistance compared to glass-body options. Evaluate the maximum dynamic impedance and reverse leakage current against circuit sensitivity requirements. Verify compatibility with the operating temperature range of -65°C to +150°C.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers an extensive voltage selection from 3.3 to 100 volts. These plastic encapsulated devices are moisture classified as Level 1 and are available in RoHS compliant versions with the e3 suffix.

Replacement Considerations

Surface mount equivalents such as SMAJ4760A or MLL4760A are available from the same manufacturer family. Consult factory documentation for other surface mount options or alternative manufacturers offering compatible 1N4760 specifications.
