Overview
The Sensata-Crydom L522F is a single-phase SCR/diode power module from the L Series, designed for printed circuit board connections. It features a maximum DC output current of 25A and supports a load voltage up to 240VAC. The device includes an integrated free-wheeling diode and exhibits an input leakage current of 300A. Key electrical ratings include a peak repetitive off-state voltage of 400V and a maximum forward impulse current of 300A. The module operates with a gate trigger current of 60mA and has a maximum forward voltage of 1.6V.
Feature Summary
- Integrated free-wheeling diode for efficient power management
- Designed specifically for printed circuit board mounting
- Single-phase bridge rectifier configuration
Applications
- Industrial motor control systems
- Power supply circuits requiring half-controlled rectification
- Solid-state relay implementations
Procurement Notes
Verify the specific datasheet version to confirm exact pinout configurations and thermal characteristics. Ensure that the PCB layout accommodates the required current density and heat dissipation needs for a 25A continuous load. Cross-reference the 400V rating against system voltage peaks to prevent overvoltage failures during operation.
Selection Notes
Select this component when a compact, PCB-mountable solution for single-phase AC/DC conversion is required. The 25A current rating suits moderate power applications. Consider the 400V blocking capability for standard industrial line voltages. Verify compatibility with existing gate drive circuits given the 60mA trigger requirement.
Part Context
The L522F belongs to the Crydom L Series of thyristor modules, which are characterized by low profile designs suitable for space-constrained electronics. This series typically offers robust performance in industrial environments, providing reliable switching and rectification capabilities for various power control applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for direct equivalents within the L Series or comparable SCR/diode modules with matching 25A and 400V ratings.
