Overview
The B481C-2T is a general-purpose silicon rectifier diode module manufactured by Sensata-Crydom. It features a single common cathode configuration with two internal diodes. The device supports a maximum DC reverse voltage of 600V and an average rectified current of 35A per diode. Forward voltage drop is specified at 1.25V when conducting 35A. The component utilizes standard recovery characteristics with a time exceeding 500ns. It operates within a junction temperature range of -40°C to 125°C and is designed for base mounting in the B48 module package.
Feature Summary
- Single common cathode dual-diode architecture
- Standard recovery speed suitable for general power applications
- Robust thermal performance across wide operating temperatures
Applications
- Industrial power supply units
- Motor drive rectification circuits
- General purpose AC to DC conversion systems
Procurement Notes
Verify the specific datasheet version from Sensata or authorized distributors to confirm mechanical dimensions and pinout compatibility before integration. Ensure that the mounting surface preparation meets the requirements for the B48 module base installation to maintain optimal thermal conductivity and electrical isolation during operation.
Selection Notes
Select this module for applications requiring high current handling with standard recovery characteristics. The 600V rating provides sufficient margin for typical industrial line voltages. Consider the 35A per diode limit when designing heat dissipation strategies, as the forward voltage drop generates significant heat under full load conditions requiring adequate thermal management.
Part Context
This component belongs to the B48 series of discrete semiconductor modules from Crydom. The series offers various voltage and current ratings within a standardized footprint. The B481C-2T specifically addresses needs for medium-power rectification where space efficiency and reliable switching are prioritized over ultra-fast recovery speeds.
Replacement Considerations
Cross-reference with other B48 series modules such as B485C-2 for similar form factors. Verify that any substitute maintains the 600V reverse voltage and 35A current ratings while matching the common cathode configuration and physical mounting dimensions.
