1N4760PE3/TR12

Overview

The Microchip Technology 1N4760PE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, manufactured by Microsemi Scottsdale Division. 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) 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 steady-state power dissipation of 1.0 W.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR12' indicates tape and reel packaging as specified in the datasheet. Confirm the manufacturer origin from Microsemi or its successor entity Microchip Technology. Ensure the component matches the JEDEC registered type number 1N4760A specifications before integration into designs.

Selection Notes

Select this component when a 68 V regulation point is required with a 1.0-watt power rating. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Verify that the ±5% tolerance meets circuit requirements, noting that tighter tolerances require different suffixes such as C or D.

Part Context

This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix designates plastic construction, while the 'e3' suffix indicates RoHS compliant devices with annealed matte-tin plating solderable per MIL-STD-750 method 2026.

Replacement Considerations

Compatible substitutes include other 1N4760A variants with identical electrical ratings. Equivalent parts may be found under different manufacturers offering the same JEDEC registration. Ensure replacement components maintain the 1.0-watt power dissipation and DO-41 package dimensions.
