1N1198

Single Diodes Overview

The Microchip Technology 1N1198 is a silicon power rectifier diode designed for high-current applications. It features a stud mount configuration within the DO-203AB (DO-5) package, providing robust mechanical stability and thermal dissipation capabilities. The device is rated for a maximum average forward current of 40A and a peak repetitive reverse voltage of 600V. This component serves as a standard recovery rectifier suitable for industrial power conversion systems requiring reliable unidirectional current flow.

Single Diodes Feature Summary

• High-power silicon construction for efficient rectification
• Stud mount design for secure installation and heat sinking
• Standard recovery characteristics for general-purpose use

Single Diodes Applications

• Industrial power supply units
• Motor drive rectification circuits
• Battery charging systems

Single Diodes Procurement Notes

Verify the manufacturer origin, as the 1N1198 designation has been produced by multiple vendors including Microsemi and others. Confirm the specific datasheet version to ensure compatibility with required electrical tolerances and mounting specifications. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure the package type matches the intended heatsink interface.

Single Diodes Selection Notes

Select this component when a 40A continuous current rating and 600V blocking voltage are required in a stud-mount form factor. Consider the thermal resistance of the DO-203AB package relative to your system's cooling strategy. Evaluate the standard recovery time against switching frequency requirements to minimize losses. Compare alternative manufacturers' pinouts and mechanical dimensions if space constraints exist.

Single Diodes Part Context

The 1N1198 belongs to the family of standard silicon power rectifiers historically associated with the 1N40xx series but scaled for higher currents. Originally documented by Microsemi Corporation, these devices are widely used in legacy and modern industrial equipment. The part number indicates a specific voltage and current class within the broader category of axial or stud-mounted power diodes.

Single Diodes Replacement Considerations

Equivalent parts include 1N1198 from other manufacturers such as Diotec or Vishay, provided they meet the 40A/600V specification. Verify that substitute components maintain the same DO-203AB package outline and stud thread specifications for direct interchangeability.
