1N2242A

Single Diodes Overview

The Microchip Technology 1N2242A is a silicon power rectifier diode designed for high-voltage applications. It features a maximum repetitive peak reverse voltage (VRRM) of 1000 V and an average forward rectified current (IO) of 5 A. The device utilizes a stud mount configuration within the DO-4 (DO-203AA) package, facilitating efficient thermal dissipation through direct mounting to heatsinks. Constructed with glass passivated die and glass-to-metal seal technology, it ensures robust performance under demanding electrical conditions.

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as listings may attribute this part number to various entities including Microsemi or generic sources. Confirm the specific datasheet version matches your voltage and current requirements. Ensure the DO-4 package dimensions align with your existing heatsink interface. Check for RoHS compliance status if required by your assembly standards, as historical versions may differ.

Single Diodes Selection Notes

Select this component when a standard 5 A, 1000 V rectifier is needed in a stud-mount form factor. Consider the thermal resistance characteristics of the DO-4 package for your heat sink design. Evaluate the forward voltage drop specifications against your efficiency targets. Ensure the surge current ratings meet the transient requirements of your specific circuit topology.

Single Diodes Part Context

This component belongs to the standard silicon rectifier family, historically associated with Microsemi Corporation before its acquisition by Microchip Technology. It serves as a legacy replacement for older Motorola and General Electric designs. The part number follows the JEDEC 1N series naming convention for general-purpose power diodes.

Single Diodes Replacement Considerations

Direct substitutes include parts from the same JEDEC series with identical electrical ratings and mechanical footprint. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' equivalents.
