B512-2

Overview

The B512-2 is a single-phase SCR bridge module from the Crydom B-2 series, manufactured by Sensata-Crydom. It utilizes silicon technology and features screw mount installation for chassis applications. The module supports a maximum operating temperature of +125°C and a minimum of -40°C. Key electrical parameters include a forward voltage of 1.65 V and a reverse voltage rating of 240 VAC. The unit weighs approximately 42.5 g and is packaged individually.

Feature Summary

• Single-phase SCR bridge configuration
• Chassis mount screw terminal interface
• Silicon semiconductor construction

Applications

• AC variable voltage output control
• Industrial power regulation systems
• High voltage application circuits

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as B512F-2 or B512-2T exist with distinct isolation barrier or pin configurations. Confirm that the required reverse voltage rating matches the 240 VAC specification for the standard B512-2 model. Ensure compatibility with chassis mounting requirements and thermal management capabilities up to 125°C. Cross-reference datasheets to confirm pinout and isolation characteristics before integration.

Selection Notes

Select the B512-2 for applications requiring a robust single-phase SCR bridge in a compact chassis-mount form factor. Consider the B512F-2 variant if isolation barriers are necessary for high-voltage safety compliance. Evaluate the B512-2T option if specific pin configurations or terminal styles differ from the standard screw mount design. Ensure the load current does not exceed the module's rated capacity under the intended thermal conditions.

Part Context

This component belongs to the Crydom B-2 and B-2T series of discrete semiconductor modules. These modules are designed for AC or DC variable voltage output applications, supporting power levels up to 15 kW. The series offers multiple circuit options and holds UL recognition (E72445). The B512-2 specifically represents the standard single-phase bridge configuration within this family.

Replacement Considerations

Public confirmed substitute part numbers include B512F-2 and B512-2T. Verify that alternative models match the 240 VAC reverse voltage rating and single-phase bridge topology. Check for differences in isolation barriers or terminal styles between the standard B512-2 and its variants.
