90SQ035

Overview

The 90SQ035 is a silicon rectifier diode manufactured by SMC Diode Solutions. It features a maximum average forward rectified current of 9 A and a maximum repetitive peak reverse voltage of 35 V. The device utilizes a DO-204AR (DO-15) axial leaded package with an isolated case connection. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 500 A, a maximum forward voltage of 0.41 V, and a maximum operating junction temperature of 150 °C.

Feature Summary

• Utilizes silicon material for robust general-purpose rectification
• Features an isolated case connection for mounting flexibility
• Designed for high thermal stability with a maximum operating temperature of 150 °C

Applications

• General purpose rectification circuits
• Power supply input stages
• DC output rectification

Procurement Notes

Verify the manufacturer designation as New Jersey Semiconductor in official datasheets, as this entity is often associated with the 90SQ series specifications. Confirm the DO-204AR package dimensions and terminal plating requirements against specific application constraints. Ensure the component meets all relevant environmental compliance standards required for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component for applications requiring a standard silicon rectifier with a 9 A current rating and low 35 V blocking capability. The DO-204AR package is suitable for through-hole mounting where space allows. Consider the 0.41 V forward voltage drop for efficiency calculations. This part is appropriate for general-purpose AC-to-DC conversion tasks rather than high-frequency switching applications.

Part Context

The 90SQ035 belongs to the 90SQ series of silicon rectifier diodes produced by New Jersey Semiconductor, which is part of the SMC Diode Solutions portfolio. These components are designed for general-purpose power rectification. The series offers various voltage ratings while maintaining consistent current handling capabilities, providing engineers with standardized options for low-voltage, medium-current power supply designs.

Replacement Considerations

Consult official substitution guides for equivalent 9 A, 35 V silicon rectifiers in the DO-204AR package. Verify that any replacement maintains identical pinout configuration, thermal resistance characteristics, and maximum voltage/current ratings to ensure circuit compatibility without redesign.
