1N1184R

Single Diodes Overview

The Microchip Technology 1N1184R is a silicon standard recovery rectifier diode designed for stud-mount applications. It features a single-phase, single-element configuration housed in a DO-203AB (DO-5) metal package with one terminal. The device supports a maximum repetitive peak reverse voltage of 100V and a continuous forward current of 35A. It exhibits a maximum non-repetitive peak forward surge current of 500A on a half-sine wave. The junction temperature range spans from -65°C to 190°C, ensuring reliable operation in demanding environments.

Single Diodes Feature Summary

• Utilizes a robust metal stud-mount construction for efficient thermal dissipation and secure mechanical attachment.
• Engineered with high surge capability to withstand transient current spikes during normal operation.
• Features standard polarity design where the stud serves as the cathode connection point.

Single Diodes Applications

• General purpose rectification circuits requiring high current handling
• Power supply units utilizing stud-mounted components
• Industrial equipment needing reliable silicon rectifiers

Single Diodes Procurement Notes

Verify the specific manufacturer source, as multiple vendors including Semitronics Corp produce this part number. Confirm RoHS compliance status, as listings indicate non-compliance. Ensure the ordering suffix matches the required polarity configuration, noting that the 'R' suffix typically denotes reverse polarity where the stud is the anode, distinct from the standard configuration.

Single Diodes Selection Notes

Select this component when a 100V rating and 35A continuous current capacity are required in a stud-mount form factor. Consider the 190°C maximum junction temperature limit for thermal management calculations. Verify compatibility with existing mounting hardware due to the DO-203AB package dimensions. Evaluate the standard recovery speed against circuit switching requirements to ensure adequate performance without excessive losses.

Single Diodes Part Context

This device belongs to the 1N1184 series of silicon standard recovery diodes manufactured by Microchip Technology. It shares the same electrical ratings and physical package as the 1N1184 but may differ in manufacturing origin or specific revision details. The series is characterized by its rugged metal construction and suitability for general-purpose power applications.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1184 for standard polarity configurations. For reverse polarity equivalents, verify availability from other manufacturers producing the JAN1N1184R specification. Ensure any replacement maintains the DO-203AB package and identical voltage and current ratings.
