F1857SDK1200

Overview

The F1857SDK1200 is a silicon-controlled rectifier module from the Crydom F18 series, manufactured by Sensata. It features a two-element configuration with series-connected SCRs and a center tap. The device supports a maximum repetitive peak reverse voltage of 1200V and an on-state current of 55A. It operates within a junction temperature range of -40°C to +125°C and includes isolated flange mounting for thermal management.

Feature Summary

Two-element series-connected SCR configuration with center tap
Isolated flange mount package design
Silicon semiconductor technology construction

Applications

Industrial power control systems
High-voltage DC switching applications
Motor drive circuits requiring high current handling

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Sensata-Crydom before procurement. Confirm that the 7-pin terminal configuration matches your board layout requirements. Ensure thermal interface materials are compatible with the isolated flange mount design for optimal heat dissipation during operation.

Selection Notes

Select this component when a high-current, high-voltage SCR module with a center-tapped configuration is required. The 1200V rating suits medium-to-high voltage AC/DC conversion tasks. Consider the 55A continuous current capacity against your load profile and ensure adequate heatsinking is available due to the flange-mount thermal path.

Part Context

This part belongs to the Crydom F18 series of discrete semiconductor modules. The series offers various voltage and current ratings in standardized packages. The F1857SDK1200 specifically targets applications needing robust SCR performance with isolated mounting capabilities for safety and thermal efficiency in industrial environments.

Replacement Considerations

Check for direct cross-references in Sensata-Crydom's replacement guides. Verify pinout compatibility and electrical ratings if substituting with other F18 series variants or competitor modules. Ensure the replacement maintains the same 7-pin flange mount configuration.
