1N4760APE3/TR8

Overview

The Microchip Technology 1N4760APE3/TR8 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 features a plastic DO-41 (DO-204AL) axial-lead package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA, a maximum reverse current of 5 µA, and a maximum forward voltage of 1.2 V at 200 mA.

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 that the ordering suffix matches the required specifications. The 'P' suffix indicates plastic construction, while 'e3' denotes RoHS compliance. Confirm the 'TR' suffix corresponds to tape and reel packaging requirements. Ensure compatibility with existing thermal management designs, as power dissipation ratings depend on lead length and board copper area. Cross-reference datasheet electrical limits against specific circuit conditions before procurement.

Selection Notes

Select this component when a 68 V Zener voltage with ±5% tolerance is required in a 1-watt plastic axial package. Consider the 150 Ohm dynamic impedance and 5 µA reverse current limits for precision requirements. Evaluate thermal resistance parameters if operating near maximum power dissipation. Compare against glass-body options if lower thermal resistance is not critical or if specific environmental constraints favor plastic encapsulation.

Part Context

This part belongs to the 1N4728AP through 1N4764AP series of silicon 1-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers an extensive voltage selection from 3.3 to 100 volts. The plastic encapsulated version provides a lower thermal resistance compared to the glass-body option for the same JEDEC part numbers. These devices are moisture classified as Level 1.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4760A variants in the DO-41 package. Verify that replacement devices meet the same 68 V nominal voltage, ±5% tolerance, and 1-watt power dissipation ratings. Ensure the alternative component supports the required operating temperature range and has compatible pinout polarity.
