1N4760P/TR8

Overview

The Microchip Technology 1N4760P/TR8 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 68 V and 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 5 µA at 51.7 V, and a maximum regulator current of 13 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 the specific ordering suffix against official documentation to confirm packaging and compliance details. The TR suffix indicates tape and reel packaging. Confirm RoHS status and screening levels if required for your application. Check current availability as product lifecycles may change. Ensure the plastic construction meets your thermal and mechanical requirements.

Selection Notes

Select this component when a 68 V Zener voltage with ±5% tolerance is required in a 1-watt power rating. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the maximum dynamic impedance and reverse leakage current specifications for precision regulation needs. Verify that the operating temperature range fits your environmental constraints.

Part Context

This part belongs to the Microsemi (now Microchip Technology) 1N4728AP through 1N4764AP series of silicon 1-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix designates plastic construction, while the 'TR' suffix indicates tape and reel packaging. These devices are JEDEC registered and available in various military screening levels with appropriate prefixes.

Replacement Considerations

Consult the manufacturer's datasheet for surface mount equivalents such as SMAJ4760A or MLL4760A. Other manufacturers producing JEDEC 1N4760A compliant parts may serve as functional substitutes if electrical parameters match.
