Overview
The Sensata-Crydom L513 is a single-phase SCR/diode bridge power module designed for through-hole PCB mounting. It features an 800 V repetitive peak off-state voltage and a 25 A RMS on-state current rating. The device incorporates a Layout 1 configuration with two SCRs and two diodes. Key electrical parameters include a non-repetitive surge current of 400 A at 60 Hz, a maximum on-state voltage of 2.2 V, and a gate trigger voltage of 3 V. The module operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- Single-phase bridge configuration integrating SCRs and diodes in a unified package
- Through-hole PCB mounting style for direct circuit board integration
- High thermal performance supporting operation up to 125°C junction temperature
Applications
- AC motor speed control systems
- Industrial heating element regulation
- Power supply rectification circuits
Procurement Notes
Verify the specific suffix designation against the manufacturer's official documentation to ensure correct voltage and current ratings. Confirm that the required pin configuration matches the target PCB footprint. Check component availability status as manufacturing lifecycles may affect long-term sourcing options.
Selection Notes
Select this module when a compact, single-phase bridge solution is required for PCB-based designs. Ensure the application current does not exceed the 25 A RMS rating under expected thermal conditions. Verify that the 800 V blocking voltage provides sufficient margin for the AC line voltage. Consider thermal management requirements given the through-hole package constraints.
Part Context
The L513 belongs to the Crydom power module family, which specializes in discrete semiconductor solutions for industrial control. This series offers various voltage and current ratings tailored for different power levels. The L513 specifically targets applications requiring moderate power handling in a space-constrained PCB environment.
Replacement Considerations
Consult official replacement lists for equivalent modules with matching voltage and current specifications. Verify pin compatibility before substituting with other single-phase bridge modules from the same or alternative manufacturers.
