Single Diodes Procurement Notes
Verify that the specific part number includes the 'R' suffix to confirm the reversed polarity configuration where the stud functions as the anode rather than the cathode. Ensure the procurement documentation explicitly references the Vishay datasheet document number 93492 to validate compliance with the specified electrical ratings and mechanical dimensions.
Single Diodes Selection Notes
Select this component when a standard recovery diode with a maximum repetitive peak reverse voltage of 800 V is required. The choice is appropriate for applications demanding a 35 A continuous forward current capability within a DO-203AB stud package. Consider the 1.1 °C/W thermal resistance for heat dissipation planning and verify compatibility with the required mounting torque specifications.
Single Diodes Part Context
This component is part of the VS-1N1183, VS-1N3765, VS-1N1183A, and VS-1N2128A series of power silicon rectifier diodes. These devices are designed for general-purpose rectification in industrial and commercial applications requiring robust performance under high voltage and current conditions.

Single Diodes FAQ
What is the polarity configuration of the VS-1N3766R?
The 'R' suffix indicates a reversed polarity configuration where the stud serves as the anode, whereas the basic type number without the suffix indicates a cathode-to-case connection.
What is the maximum non-repetitive surge current rating?
The maximum peak one cycle non-repetitive surge current is 400 A for a half-cycle 60 Hz sine wave or 5 ms rectangular pulse following any rated load condition.
