1N4759PE3/TR8

Overview

The Microchip Technology 1N4759PE3/TR8 is a silicon Zener diode rated for 1.0 watts of power dissipation at 25°C, housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation with a nominal Zener voltage of 62 volts and a standard tolerance of ±5%. The device operates within an ambient temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals suitable 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 62 V reference
• Power supply protection against overvoltage conditions
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm material composition and packaging type. Ensure that the ordering suffix aligns with the required terminal plating and reel specifications. Cross-reference the manufacturer's latest documentation to validate compliance status and environmental classifications before procurement.

Selection Notes

Select this component when a 62 V Zener voltage with ±5% tolerance is required for through-hole assembly. Consider the 1.0 W power rating and thermal resistance characteristics for heat dissipation requirements. Verify compatibility with existing circuit designs regarding test currents and dynamic impedance values specified in the electrical characteristics table.

Part Context

This part belongs to the 1N4728AP through 1N4764AP series of 1-watt plastic encapsulated Zener diodes manufactured by Microsemi (now Microchip). The series offers extensive voltage selection from 3.3 to 100 volts. The 'e3' suffix indicates RoHS compliance, while the 'TR8' suffix denotes tape and reel packaging options available for automated assembly processes.

Replacement Considerations

Consult the manufacturer for surface mount equivalents such as SMAJ or MLL series devices. Verify functional compatibility with other 1N4759 variants differing only in tolerance or body material.
