1N4594

Single Diodes Overview

The GeneSiC Semiconductor 1N4594 is a silicon standard recovery rectifier housed in a DO-8 stud mount package. It supports a repetitive peak reverse voltage of 1000 V and a continuous forward current of 150 A. The device features a maximum surge non-repetitive forward current of 3000 A and an I2t rating of 37200 A²sec for fusing applications. Electrical characteristics include a forward voltage of 1.5 V at 150 A and a thermal resistance from junction to case of 0.35 °C/W. The component operates within a temperature range of -55 °C to 150 °C.

Single Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm terminal configuration, as the 'R' variant indicates reversed polarity where the stud serves as the anode rather than the cathode. Confirm that the required reverse voltage rating aligns with the 1000 V specification for the standard 1N4594 model. Ensure mounting hardware compatibility with the 3/8-24 UNF thread specified in the mechanical dimensions.

Single Diodes Selection Notes

Select this component for high-current applications requiring a single-phase or three-phase rectification topology with stud mounting. The low thermal resistance facilitates efficient heat dissipation in constrained spaces. Consider the 150 A continuous current rating and 3000 A surge capacity when designing for transient load conditions. Verify that the operating temperature range meets the environmental requirements of the target application.

Single Diodes Part Context

This device belongs to the 1N4594(R) through 1N4596(R) series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series offers varying reverse voltage ratings from 1000 V to 1400 V while maintaining consistent current and thermal characteristics across the lineup.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-8 packaged silicon rectifiers with equivalent 1000 V and 150 A ratings. Verify mechanical fitment and electrical parameters before substitution.

Single Diodes FAQ

What is the polarity configuration for the standard 1N4594?

The standard polarity configuration has the stud serving as the cathode.

How does the 'R' suffix affect the terminal configuration?

Devices with the 'R' suffix have reversed polarity, meaning the stud functions as the anode.
