1N4760P/TR12

Overview

The Microchip Technology 1N4760P/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. 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 maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA. It includes a tape and reel option for automated assembly.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable for standard PCB layouts
• 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 manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while other records list Microchip Technology. Confirm RoHS compliance status and suffix definitions directly with the supplier or official documentation before procurement. Ensure the ordering part number matches the required plastic construction and tape-and-reel packaging specifications.

Selection Notes

Select this component when a 68 V Zener voltage with ±5% tolerance is required in a 1-watt power dissipation class. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the tape-and-reel configuration for high-volume automated surface mount or through-hole assembly processes.

Part Context

This component belongs to the JEDEC registered 1N4728A to 1N4764A series of silicon Zener diodes. The 'P' suffix designates plastic encapsulation, distinguishing it from glass-body variants. The 'TR' suffix indicates availability in tape and reel packaging, facilitating efficient manufacturing integration.

Replacement Considerations

Direct replacements include other manufacturers' 1N4760A or 1N4760AP equivalents. Verify that substitute parts match the 68 V nominal voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
