1N4758CE3/TR13

Overview

The Microchip Technology 1N4758CE3/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 with a nominal Zener voltage of 56 V and 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 per EIA-296 standards as denoted by the 'TR13' suffix, it offers flexible mounting terminals and void-free transfer molded epoxy construction.

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 (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation circuits requiring precise 56 V reference levels
• Power supply protection and over-voltage clamping applications
• General-purpose electronic equipment utilizing axial-lead components

Procurement Notes

Verify that the specific part number matches the required electrical characteristics, particularly the 56 V Zener voltage and ±2% tolerance associated with the 'C' suffix. Confirm the presence of the 'e3' suffix for RoHS compliance and the 'TR13' designation for tape and reel packaging. Ensure compatibility with the specified thermal resistance and power dissipation limits during operation.

Selection Notes

Select this component when a 1-watt power rating and axial-lead form factor are required for robust mechanical mounting. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard 5% or 10% variants. Consider the plastic package's lower thermal resistance compared to glass-body options if heat dissipation efficiency is a priority in the design.

Part Context

This device belongs to the widely used 1N47xx series of silicon Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series covers a voltage range from 3.3 V to 100 V, offering extensive selection for various regulation needs. The specific 1N4758 variant sits within the mid-to-high voltage segment of this lineup, providing reliable performance in industrial and commercial electronics.

Replacement Considerations

Compatible replacements include other 1N4758 variants with matching voltage and tolerance, such as the glass-body 1N4758G or surface-mount equivalents like SMAJ4758A. Verify that any substitute maintains the 1-watt power dissipation rating and compatible package dimensions for direct interchangeability.
