Overview
The L312F is a thyristor module from the Crydom L Series, designed for high-power industrial applications. It features a half-controlled bridge configuration with a common cathode and an integrated built-in diode. The device utilizes a flange mount package for efficient thermal management. Key electrical characteristics include a maximum holding current of 100 mA and a maximum DC gate trigger voltage of 2.5 V. It supports a peak non-repetitive on-state current of 150 A and operates within a temperature range of -40°C to 125°C.
Feature Summary
- Half-controlled bridge configuration with common cathode
- Integrated built-in diode for simplified circuit design
- Flange mount package for robust mechanical stability
- High surge current capability for demanding loads
Applications
- Industrial motor control systems
- Power regulation circuits
- Heating element control
- DC power supply rectification
Procurement Notes
Verify the specific suffix or variant code against official Sensata-Crydom documentation to ensure compatibility with your system requirements. Confirm that the flange mounting interface matches your heat sink specifications. Check for RoHS compliance status if required by your manufacturing standards. Ensure proper handling procedures are followed due to the sensitive semiconductor nature of the component.
Selection Notes
Select the L312F when a half-controlled bridge topology is required with integrated diode functionality. Consider its 150 A surge capacity for applications involving inrush currents. Evaluate the thermal resistance of the flange mount against your cooling solution. Compare gate trigger parameters with your control circuit capabilities to ensure reliable switching performance under varying load conditions.
Part Context
The L312F belongs to the Crydom L Series of SCR modules, which are engineered for heavy-duty industrial environments. This series emphasizes durability and precise control in power electronics. The L312F specifically addresses applications needing controlled rectification with inherent freewheeling path provided by the built-in diode, simplifying overall system architecture and reducing component count.
Replacement Considerations
Consult official Sensata-Crydom cross-reference guides for verified substitutes. Ensure any replacement maintains the same half-controlled bridge configuration and common cathode arrangement. Verify that thermal and electrical ratings meet or exceed original specifications.
