Scrs Procurement Notes
Verify the specific suffix CFN1 against official Vishay documentation to confirm pinout and mechanical tolerances. Confirm RoHS compliance status via the manufacturer's latest datasheet. Ensure the procurement channel provides authentic components with traceable manufacturing dates. Cross-reference the part number with the distributor's inventory status as availability may vary.
Scrs Selection Notes
Select this component when high current handling and robust surge capability are required in industrial power applications. The 800 V rating suits medium-voltage AC/DC conversion tasks. Consider the TO-200AB package dimensions for heatsink compatibility. Evaluate gate drive requirements against the specified 3 V and 200 mA limits to ensure proper triggering circuitry design.
Scrs Part Context
This device belongs to the VS-ST303C series of inverter-grade thyristors from Vishay. The series is designed for demanding industrial environments requiring high reliability. The E-PUK packaging variant offers standardized mounting interfaces compatible with common industrial cooling solutions. This specific model represents a high-current option within the broader ST303 product family.
Scrs Replacement Considerations
Direct substitutes include the VS-ST303C04CFN1 for lower voltage applications or other variants within the VS-ST303C series sharing the same E-PUK package. Verify that alternative parts match the 1180 A RMS current rating and 800 V blocking voltage. Ensure thermal impedance and gate trigger parameters remain compatible with existing circuit designs.
