1N4760AP/TR12

Single Zener Diodes Overview

The Microchip Technology 1N4760AP/TR12 is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 68 V and a maximum power dissipation of 1.0 W at 25°C. It features a 5% tolerance on the nominal Zener voltage, indicated by the 'A' suffix. The device utilizes a plastic molded epoxy body (DO-41 or DO-204AL) and is supplied in tape and reel packaging, denoted by the 'TR' suffix. Electrical characteristics include a test current of 3.7 mA, a maximum dynamic impedance of 150 Ohms at the test current, and a maximum reverse current of 5 µA at a test voltage of 51.7 V.

Single Zener Diodes Feature Summary

• Provides 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
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Protection against overvoltage conditions in electronic systems
• Clamping applications for transient voltage suppression

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required plastic package variant and tape and reel configuration. Confirm RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the supplier provides documentation confirming the 5% voltage tolerance associated with the 'A' suffix designation.

Single Zener Diodes Selection Notes

Select this component when a 68 V regulation point is required with a 1 W power handling capability. The plastic construction offers lower thermal resistance compared to glass-body options. Consider the axial lead form factor for manual assembly or standard PCB footprints. Verify that the operating temperature range of -65°C to +150°C meets the environmental requirements of the target application.

Single Zener Diodes Part Context

This component belongs to the 1N4728AP through 1N4764AP series of 1.0 Watt Zener diodes manufactured by Microsemi (now part of Microchip Technology). The series covers a wide voltage selection from 3.3 to 100 volts. The 'P' suffix specifically designates the plastic encapsulated version, distinguishing it from the glass-body variants available within the same JEDEC numbering system.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 68 V Zener voltage, 1 W power rating, and DO-41/DO-204AL plastic package. Equivalent parts should maintain the 5% voltage tolerance and similar dynamic impedance characteristics. Verify compatibility with existing PCB footprints and thermal management requirements.
