1N4758E3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N4758E3/TR13 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation at a nominal Zener voltage of 56 volts with a standard tolerance of plus or minus 5%. The device operates within a temperature range of -65°C to +150°C and features a plastic encapsulated body in a DO-41 axial lead package. It includes RoHS compliant annealed matte-tin plating and tape-and-reel packaging.

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 in power supply circuits
• Reference voltage generation in electronic systems
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications, specifically confirming the 'e3' designation indicates RoHS compliance and the 'TR' suffix confirms tape-and-reel packaging. Ensure the component meets the specific voltage tolerance requirements for your design, as standard tolerances apply unless otherwise specified by additional suffixes.

Single Zener Diodes Selection Notes

Select this component when a 56-volt regulation point is required with a 1-watt power dissipation capability. Consider the plastic DO-41 package for its lower thermal resistance compared to glass-body options. Verify compatibility with assembly processes regarding the RoHS compliant tin plating and moisture classification level.

Single Zener Diodes Part Context

This part belongs to the popular 1N4728A through 1N4764A series of 1.0-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix denotes plastic construction, while the 'e3' suffix indicates RoHS compliance.

Single Zener Diodes Replacement Considerations

Consult the manufacturer for surface mount equivalents such as SMAJ4758A or MLL4758A. Other variants within the 1N4758 series may be available with different voltage tolerances indicated by suffix letters like C or D.
