Overview
The F1857SDK1000 is a silicon-based discrete semiconductor module from the Crydom F18 series, manufactured by Sensata. It functions as an SCR-Diode module with a chassis mount style and screw mounting interface. The component features a repetitive peak reverse voltage of 380 VAC and a maximum forward voltage of 1.4 V. Designed for operation within a temperature range of -40°C to +125°C, it utilizes standard packaging.
Feature Summary
- Integrates two SCRs in series configuration for controlled rectification applications
- Utilizes silicon technology for robust power switching performance
- Supports secure installation via screw mount chassis interface
Applications
- Industrial motor control systems
- Power supply regulation circuits
- Resistive load heating control
Procurement Notes
Verify the specific suffix designation against official datasheets to confirm electrical ratings and pinout compatibility. Ensure thermal management requirements align with the specified operating temperature range. Confirm that the chassis mount form factor fits the intended enclosure design before finalizing procurement orders.
Selection Notes
Select this module when a dual-SCR series configuration is required for high-current AC control. The 55A rating suits moderate power industrial loads. Verify that the 380VAC blocking capability matches the system line voltage. Consider the physical dimensions and screw mounting requirements during mechanical integration planning.
Part Context
This component belongs to the F18 series of power modules, which are designed for general-purpose industrial applications. The SDK variant specifically denotes an SCR-Diode combination, offering both rectification and phase-control capabilities within a single compact package suitable for panel mounting.
Replacement Considerations
Cross-reference part numbers such as F1857SDK600 or F1857SDK1200 if voltage ratings differ. Verify current handling capabilities and thermal characteristics match the original design specifications before substituting.
