1N5393

Overview

The onsemi 1N5393 is a standard recovery rectifier diode designed for general-purpose applications. It features a single configuration housed in a DO-15 package with through-hole mounting. The device supports a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 200 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 50 A, a typical reverse leakage current of 5 uA, and a maximum forward voltage drop of 1.4 V. The component operates within a junction temperature range up to 175 °C.

Feature Summary

• Glass-passivated junction construction for high reliability
• Low forward voltage drop for improved efficiency
• High forward surge current capability
• Low reverse leakage current

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diode implementations

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N5393 JEDEC number is utilized by multiple vendors including Vishay and Diotec. Confirm that the procured unit matches the required DO-15 package and 200V rating specifications. Ensure compliance with environmental standards such as RoHS if applicable to the project requirements. Cross-reference datasheets from authorized distributors to confirm exact electrical tolerances and packaging details before integration.

Selection Notes

Select this component for designs requiring robust standard recovery performance in medium-current applications. The 1.5 A current rating and 200 V blocking voltage make it suitable for low-to-medium voltage AC/DC conversion tasks. Consider the thermal management capabilities provided by the DO-15 package for heat dissipation. Evaluate the trade-off between the standard recovery time and cost compared to faster switching alternatives if high-frequency operation is required.

Part Context

The 1N5393 belongs to the widely recognized 1N53xx series of silicon rectifier diodes. This family is characterized by glass-passivated junctions and plastic encapsulation, offering a balance of performance and durability. The series covers various voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A average forward current capability across all variants.

Replacement Considerations

Compatible substitutes include the Vishay 1N5393GP/56-E3 and Diotec Semiconductor 1N5393. These parts share identical JEDEC mechanical dimensions and electrical ratings, ensuring direct pin-for-pin replacement in existing PCB layouts without circuit modification.
