1N5406

Overview

The onsemi 1N5406 is a general-purpose silicon rectifier diode housed in the DO-201AD axial leaded package. It provides a maximum repetitive reverse voltage of 600 V and supports an average rectified forward current of 3.0 A at 75°C ambient temperature without thermal runaway. The device features a non-repetitive peak forward surge current capability of 200 A for 8.3 ms half-sine-wave pulses. Electrical characteristics include a maximum forward voltage of 1.2 V at 3.0 A, a reverse current of 5.0 µA at rated voltage and 25°C, and a total capacitance of 30 pF. Operating junction temperatures range from -55°C to +150°C.

Procurement Notes

Verify authenticity by purchasing directly from ON Semiconductor or authorized distributors to ensure traceability and compliance with quality standards. Confirm the specific package variant matches design requirements. Review the datasheet for absolute maximum ratings to prevent overstressing during application validation. Ensure end-use complies with authorized use policies excluding life support or medical implantation.

Selection Notes

Select this component for standard commercial applications requiring reliable rectification at 600 V blocking voltage. Evaluate thermal resistance and derating curves for high ambient temperature environments. Compare against other members of the 1N540x series if different voltage ratings are needed. Validate electrical parameters against specific circuit load conditions before finalizing the design.

Part Context

This part belongs to the 1N5401 through 1N5408 family of general-purpose rectifiers manufactured by ON Semiconductor. The series shares identical current and surge capabilities while varying only in maximum repetitive reverse voltage ratings. The 1N5406 specifically targets applications requiring 600 V isolation within a standard plastic epoxy molded case.

Replacement Considerations

Cross-reference with Vishay 1N5406-E3/73 or generic equivalents sharing the DO-201AD package and 600V/3A specifications. Verify pinout polarity and physical dimensions match existing board layouts. Confirm that alternative manufacturers meet the same thermal and electrical performance criteria.
