Overview
The Littelfuse S4055RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series, designed for phase control applications. It features a 400 V rated repetitive off-state voltage and handles an RMS on-state current of 55 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a maximum gate trigger current of 40 mA, a forward voltage of 1.8 V, and a holding current of 60 mA. It exhibits a non-repetitive peak on-state current capability of 650 A and maintains a low off-state leakage current of 10 µA.
Feature Summary
- Standard phase control SCR with high surge current handling
- Low gate drive requirements for efficient triggering
- Robust thermal performance in industrial environments
Applications
- Heating control systems
- Motor speed controls
- Phase control circuits
Procurement Notes
Verify the specific ordering suffix to confirm the package type and lead-free status. Confirm RoHS compliance details directly with the manufacturer or authorized distributor documentation. Ensure the procurement channel provides valid traceability for the Littelfuse Teccor brand component.
Selection Notes
Select this component when a 55 A RMS current rating and 400 V blocking voltage are required in a through-hole configuration. Consider the TO-220-2 package for adequate heat dissipation in standard phase control designs. Verify that the 40 mA gate trigger current aligns with the available driver circuit capabilities.
Part Context
This part belongs to the Littelfuse Sxx55x series of standard SCRs. These devices are engineered as excellent unidirectional switches for power control. The series offers junction voltages up to 1000 V and is characterized by reliable switching performance in demanding AC power applications.
Replacement Considerations
Cross-reference with other parts in the Sxx55x series for different voltage ratings. Check for equivalent SCRs from other manufacturers offering identical 55 A / 400 V specifications in a TO-220-2 package.
