1N4759CE3/TR13

Overview

The Microchip Technology 1N4759CE3/TR13 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 tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance via the 'e3' suffix. Packaged in tape and reel format as denoted by the 'TR13' suffix, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

Feature Summary

• Provides precise voltage regulation with a ±2% tolerance for stable reference applications
• Features a plastic encapsulated body offering lower thermal resistance compared to glass-body options
• Includes flexible axial-lead terminals suitable for standard through-hole mounting techniques
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0 standards

Applications

• Voltage regulation circuits requiring stable reference levels
• Protection against overvoltage conditions in electronic systems
• Clamping applications for transient voltage suppression

Procurement Notes

Verify the specific ordering suffixes to confirm component attributes. The 'e3' suffix indicates RoHS compliance, while the 'C' suffix confirms the ±2% voltage tolerance. The 'TR13' designation specifies the tape and reel packaging format. Ensure the procurement request matches these identifiers exactly to secure the correct variant from the manufacturer's distribution channels.

Selection Notes

Select this component when a 62-volt regulation point with high precision is required. The ±2% tolerance makes it suitable for applications demanding tighter voltage control than standard 5% or 10% variants. Consider the 1.0-watt power dissipation rating and the operating temperature range to ensure compatibility with the thermal environment of the target circuit design.

Part Context

This part belongs to the widely used 1N47xx series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a broad voltage selection from 3.3 to 100 volts. The 1N4759A variant specifically targets the 62-volt region, providing a standardized solution for designers needing reliable voltage references in discrete semiconductor form factors.

Replacement Considerations

Compatible replacements include other 1N4759 variants with matching electrical characteristics. Verify that substitute parts maintain the same 62-volt Zener voltage, 1.0-watt power rating, and ±2% tolerance. Ensure the replacement package type and pinout are compatible with the existing PCB layout.
