L311

Overview

The L311 is a single-phase SCR/diode bridge module manufactured by Sensata-Crydom. It features a PCB mounting style and contains two SCRs and two diodes in Layout 1 configuration. The device supports an operating voltage of 120VAC with a maximum load current of 15A. Key electrical parameters include an on-state voltage of 2.2V at 15A and a gate trigger current (Igt) of 60mA. The component is currently marked as obsolete.

Feature Summary

Single-phase bridge rectifier structure combining SCRs and diodes
Designed for printed circuit board installation
Utilizes standard Layout 1 internal configuration

Applications

AC power control circuits requiring phase-angle firing
Rectification applications utilizing mixed semiconductor elements
Industrial equipment using legacy Crydom modules

Procurement Notes

Verify availability through authorized distributors or secondary markets, as the L311 is officially listed as obsolete by the manufacturer. Confirm that replacement components match the required 15A load capacity and 120VAC rating. Ensure the substitute part supports identical PCB footprint dimensions and pinout configurations to maintain mechanical compatibility.

Selection Notes

Select this component only if the specific Layout 1 architecture and mixed SCR/diode functionality are mandatory for the design. Evaluate alternative active modules if current requirements exceed 15A or if voltage ratings must surpass 120VAC. Consider thermal management needs associated with the specified on-state voltage drop during continuous operation.

Part Context

This module belongs to the broader Crydom family of power switching devices. It represents a specialized hybrid solution integrating thyristor and diode technologies within a single package. The product serves niche applications where traditional full-bridge rectifiers or pure SCR bridges do not meet specific circuit topology requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the component's obsolete status. Engineers should consult official replacement guides from Sensata-Crydom for modern equivalents.
