1N3768R

Single Diodes Overview

The GeneSiC Semiconductor 1N3768R is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud package. It features a repetitive peak reverse voltage of 1000 V and a continuous forward current rating of 35 A at a case temperature of 25 °C. The device supports a surge non-repetitive forward current of 475 A for half-sine wave pulses. Electrical characteristics include a maximum forward voltage of 1.2 V at 35 A and a reverse leakage current of 10 µA at 50 V and 25 °C. The junction-to-case thermal resistance is specified as 0.25 °C/W, with an operating temperature range from -55 °C to 150 °C.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Reverse polarity configuration where the stud terminal functions as the anode
• Not sensitive to electrostatic discharge events

Single Diodes Applications

• General purpose rectification circuits
• Power supply input stages
• Industrial equipment power conversion

Single Diodes Procurement Notes

Verify that the specific part number suffix indicates the reverse polarity variant where the stud serves as the anode, distinct from standard polarity versions. Confirm the manufacturer source matches GeneSiC Semiconductor specifications. Ensure the component meets required thermal management constraints given the 0.25 °C/W junction-to-case resistance. Check for compliance with relevant environmental standards if applicable to the final assembly.

Single Diodes Selection Notes

Select this component when a high-voltage 1000 V rating and 35 A continuous current capacity are required in a stud-mount form factor. The reverse polarity design simplifies mounting configurations where the base must connect to the positive rail. Consider the thermal resistance value for heatsink sizing to maintain junction temperatures within the 150 °C limit during operation.

Single Diodes Part Context

This device belongs to the 1N3765 through 1N3768R series of silicon standard recovery diodes. The series offers varying reverse voltage ratings from 700 V to 1000 V while maintaining a consistent 35 A forward current capability across all variants. All members share the same DO-5 package dimensions and thermal characteristics.

Single Diodes Replacement Considerations

Compatible substitutes include other 1000 V, 35 A stud-mount rectifiers in the DO-5 package. Verify that replacement parts match the reverse polarity requirement (stud as anode) and have equivalent or lower thermal resistance values.
