1N4759PE3/TR12

Overview

The Microchip Technology 1N4759PE3/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 at a nominal Zener voltage of 62 volts with a standard tolerance of plus or minus 5%. The device features a maximum dynamic impedance of 125 ohms and a maximum reverse current of 5 microamperes. It operates within a temperature range of -65°C to +150°C and includes RoHS compliance indicated by the e3 suffix.

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

Applications

• Voltage regulation circuits requiring 62-volt reference levels
• Power supply protection and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the ordering suffix TR12 corresponds to tape and reel packaging as specified in the datasheet. Confirm RoHS compliance status via the e3 suffix. Ensure the component matches the JEDEC registered type number 1N4759A with the A suffix indicating 5% voltage tolerance. Check for any specific military screening prefixes if required for the application environment.

Selection Notes

Select this component when a 62-volt Zener diode with 1-watt power dissipation is required in an axial-lead package. The plastic construction offers lower thermal resistance compared to glass-body options. Consider the 5% standard tolerance unless tighter specifications are needed, which require different suffix identifiers. Verify lead length requirements against the specified 3/8 inch measurement for thermal calculations.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N4728AP through 1N4764AP series of silicon Zener diodes. The series covers a voltage selection from 3.3 to 100 volts. The P suffix designates plastic encapsulation, while the e3 suffix indicates RoHS compliant devices. These diodes are JEDEC registered and available in various screening levels upon request.

Replacement Considerations

Equivalent parts include other 1N4759A variants with compatible voltage and power ratings. Plastic body equivalents may be substituted for glass body versions due to lower thermal resistance. Surface mount alternatives such as SMAJ4759A are available but require layout changes.
