1N1193

Single Diodes Overview

The Microchip Technology 1N1193 is a standard recovery rectifier diode designed for high-current applications. It features a maximum DC reverse voltage of 150 V and an average forward current rating of 40 A. The device utilizes a DO-203AB (DO-5) leaded package suitable for terminal mounting. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 150 V and a typical forward voltage drop of 1.19 V at 90 A. It operates within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature of 200°C
• Robust construction in a DO-203AB terminal mount package
• Standard recovery speed suitable for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific suffix or variant when ordering, as the base number may refer to a family. Confirm RoHS compliance status, as historical data indicates non-compliance for some variants. Ensure the DO-203AB package style matches the board layout requirements. Check datasheet revisions for any changes in mechanical dimensions or electrical limits before finalizing the design.

Single Diodes Selection Notes

Select this component for designs requiring high surge current handling and wide operating temperature ranges. The 150 V rating limits its use to low-voltage AC-to-DC conversion stages. Consider the thermal resistance of the DO-203AB package for heat dissipation planning. Compare against faster recovery diodes if switching frequency exceeds standard rectification needs.

Single Diodes Part Context

This part belongs to the 1N1193 series of silicon rectifiers manufactured by Microchip Technology. It is a legacy through-hole component often used in robust industrial environments where reliability under high stress is critical. The DO-203AB package provides strong mechanical anchoring for heavy-duty wiring connections.

Single Diodes Replacement Considerations

Substitutes must match the 40 A current rating and 150 V reverse voltage. Verify that replacement packages are compatible with existing terminal mounts. Ensure the replacement diode meets or exceeds the 200°C junction temperature specification.
