1N4759APE3/TR12

Overview

The 1N4759APE3/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, manufactured by Microsemi (Microchip Technology). It provides voltage regulation at a nominal Zener voltage of 62 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 5 µA at a test voltage of 47.1 V. It utilizes a DO-41 or DO-204AL plastic axial-lead package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals 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 and clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify component authenticity against official Microchip Technology documentation. Confirm that the ordering suffixes correspond to the specified plastic construction and tape-and-reel packaging format. Ensure compliance with RoHS requirements as indicated by the e3 suffix. Cross-reference part numbers with current datasheets to validate electrical characteristics and mechanical specifications before integration.

Selection Notes

Select this component for applications requiring a 62 V Zener voltage with ±5% tolerance. The plastic encapsulation offers lower thermal resistance compared to glass-body options. Verify that the 1.0 W power dissipation rating and -65°C to +150°C operating temperature range meet system requirements. Consider the axial-lead package dimensions for PCB layout compatibility.

Part Context
