1N4759APE3/TR8

Single Zener Diodes Overview

The Microchip Technology 1N4759APE3/TR8 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series, manufactured by Microsemi. It features a plastic encapsulated DO-41 (DO-204AL) axial-lead package with an e3 suffix indicating RoHS compliance and annealed matte-tin plating. The device provides voltage regulation at a nominal Zener voltage of 62 volts with a standard 5% tolerance. Key electrical parameters include a test current of 4.0 mA, a maximum dynamic impedance of 125 ohms at the test current, and a maximum reverse current of 5 µA at a test voltage of 5 volts. The component supports a steady-state power dissipation of 1.0 watt and operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features flexible axial-lead mounting terminals for standard through-hole integration.
• 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 62V reference.
• Overvoltage protection for electronic systems.
• Power supply output stabilization.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR8 corresponds to the tape and reel packaging option described in the datasheet as adding a TR suffix. Confirm the e3 suffix indicates RoHS compliant annealed matte-tin plating. Ensure the A suffix is present to guarantee the specified 5% voltage tolerance rather than the standard 10% tolerance associated with no suffix identification.

Single Zener Diodes Selection Notes

Select this component when a 62-volt Zener reference with 5% tolerance is required in a plastic axial-lead package. The 1-watt power rating and wide thermal operating range make it suitable for general-purpose regulation. Consider the plastic construction for lower thermal resistance compared to glass-body options if heat dissipation characteristics are critical for the specific PCB layout.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. The plastic encapsulated variants provide moisture classification Level 1 without requiring dry pack storage, facilitating easier handling and assembly compared to other moisture-sensitive components.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMAJ4759A or MLL4759A are available from the same manufacturer family. Verify pin compatibility and thermal management requirements when transitioning between axial-lead and surface-mount form factors.
