1N1193A

Single Diodes Overview

The Microchip Technology 1N1193A is a standard recovery silicon rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 150 V and an average forward rectified current (Io) of 40 A. The device exhibits a typical forward voltage (Vf) of 1.19 V at 90 A and a reverse leakage current of 10 µA at 150 V. Housed in the DO-203AB (DO-5) stud mount package, it supports a junction temperature range from -65°C to +200°C.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of 200°C
• Robust surge current capability suitable for demanding power environments
• Low reverse leakage current ensuring efficient operation under reverse bias

Single Diodes Applications

Single Diodes Procurement Notes

Verify the specific manufacturing lot date code against project requirements, as lead times may vary. Confirm RoHS compliance status, as this component series may not meet current environmental directives depending on the production batch. Ensure the ordering suffix matches the required packaging configuration before finalizing procurement orders.

Single Diodes Selection Notes

Select the 1N1193A when a 150 V blocking voltage and 40 A continuous current are required in a stud-mount form factor. Consider the 200°C junction temperature limit for high-temperature environments. Evaluate thermal management needs based on the 1.19 V forward voltage drop at rated current to ensure adequate heat sinking.

Single Diodes Part Context

This component belongs to the 1N1193 basic product family, which includes variants with different voltage ratings. It is manufactured by Microchip Technology using established silicon rectifier processes. The DO-203AB package provides a robust mechanical interface for high-current mounting solutions.

Single Diodes Replacement Considerations

Cross-reference with other 1N1193 series variants if voltage or current ratings differ. Verify pinout compatibility and thermal resistance characteristics when substituting with equivalent parts from other manufacturers.
