1N1186A

Single Diodes Overview

The GeneSiC Semiconductor 1N1186A is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud mount package. It supports a repetitive peak reverse voltage of 200 V and conducts a continuous forward current of 40 A. The device features a maximum non-repetitive surge forward current of 800 A for half-sine wave pulses. Electrical characteristics include a forward voltage of 1.1 V at 40 A and a reverse leakage current of 10 µA at 50 V. The junction-to-case thermal resistance is 1.25 °C/W, with an operating temperature range from -55 °C to +150 °C.

Single Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm terminal configuration. Standard versions utilize a cathode stud, while reversed polarity variants feature an anode stud. Ensure the procurement specification matches the required electrical orientation for the intended circuit topology to prevent installation errors.

Single Diodes Selection Notes

Select this component for applications requiring robust standard recovery performance in high-current environments. The DO-5 package facilitates efficient heat dissipation through direct chassis mounting. Evaluate the thermal management requirements based on the specified junction-to-case resistance and ensure the cooling system maintains the junction temperature within the rated operational limits during continuous operation.

Single Diodes Part Context

This component belongs to the 1N1183A through 1N1190AR series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series shares common physical dimensions and thermal characteristics, differing primarily in their voltage ratings. The 1N1186A specifically addresses the 200 V blocking requirement within this lineup.

Single Diodes Replacement Considerations

Compatible substitutes within the same series include the 1N1183A, 1N1184A, and 1N1188A, provided the voltage rating meets or exceeds the circuit requirements. Verify that the replacement device maintains the same DO-5 package footprint and stud polarity configuration to ensure mechanical compatibility.
