1N3618

Single Diodes Overview

The Microchip Technology 1N3618 is a silicon power rectifier diode designed for high-reliability applications. It features a single-element configuration with a maximum average forward rectified current of 16A and a peak non-repetitive surge current rating of 400A. The device supports a maximum repetitive reverse voltage (VRRM) of 200V and exhibits a maximum forward voltage drop of 1.1V at rated current. Constructed with glass passivation and a metal seal, it operates within a junction temperature range up to 200°C and utilizes the DO-4 (DO-203AA) stud mount package.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Metal seal design ensuring robust environmental protection
• High surge current capability for transient load handling

Single Diodes Applications

• Power supply rectification circuits
• Industrial power conversion systems
• High-reliability electronic assemblies

Single Diodes Procurement Notes

Verify the manufacturer designation on the component marking, as historical production involved Microsemi which was acquired by Microchip Technology. Confirm the specific suffix or date code if strict lineage tracking is required for aerospace or defense programs. Ensure the DO-4 package dimensions match the mechanical constraints of the target heatsink interface.

Single Diodes Selection Notes

Select this component when a standard recovery silicon rectifier with a stud mount form factor is required. The 16A continuous current rating and 200V blocking voltage define its operational envelope. Consider the thermal resistance of the DO-4 package and the necessity of an insulating washer if mounting to a grounded chassis.

Single Diodes Part Context

This part belongs to the family of standard silicon power rectifiers utilizing the DO-4 metal case style. These components are characterized by their ruggedness and suitability for industrial environments where through-hole stud mounting provides superior thermal dissipation compared to surface-mount alternatives.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent DO-4 packaged rectifiers with matching 16A/200V ratings. Verify that any substitute maintains the same glass-to-metal seal construction and forward voltage characteristics to ensure circuit compatibility.
