1N5407

Overview

The 1N5407 is a silicon rectifier diode manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 800V and an average forward rectified current of 3A. The device utilizes a DO-201AD plastic axial package with isolated cathode connection. It operates within a junction temperature range of -50°C to 150°C and supports a non-repetitive peak forward surge current of 200A.

Feature Summary

• High voltage blocking capability suitable for demanding power applications
• Low leakage current characteristics for improved efficiency
• Robust construction designed for general-purpose free-wheeling duties

Applications

• General purpose rectification circuits
• Free-wheeling diode configurations in inductive loads
• Power supply input stages requiring high reverse voltage tolerance

Procurement Notes

Verify the specific manufacturer designation, as the 1N5407 is a generic JEDEC part number produced by multiple vendors. Confirm that the supplied component matches the required 800V rating and DO-201AD package dimensions. Ensure compliance with relevant environmental standards such as RoHS if applicable to your assembly process before finalizing procurement.

Selection Notes

Select this component when a standard 3A silicon rectifier with an 800V reverse voltage rating is required. The DO-201AD axial package facilitates through-hole mounting on printed circuit boards. Consider the thermal management requirements associated with the 150°C maximum junction temperature limit during continuous operation in enclosed environments.

Part Context

This component belongs to the widely recognized 1N54xx series of axial leaded rectifier diodes. These devices are standard industry replacements for legacy designs requiring moderate current handling and high reverse voltage endurance. The 1N5407 specifically denotes the 800V variant within this family, distinguishing it from lower voltage counterparts like the 1N5404 or 1N5406.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5407 parts meeting identical electrical specifications. Equivalent alternatives may include the SR580 or similar 800V 3A axial rectifiers, provided pinout compatibility and thermal ratings align with the original design constraints.
