Overview
The S6055WTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-power switching applications. It features a non-isolated configuration with a maximum repetitive peak off-state voltage of 600 V and a maximum RMS on-state current of 55 A. The device utilizes a TO-220AB flange mount package to facilitate efficient heat dissipation. Key electrical characteristics include a maximum gate trigger current of 40 mA and a forward voltage drop of approximately 1.8 V at rated current. It operates within a junction temperature range of -40°C to +125°C and supports a non-repetitive surge current of up to 650 A.
Feature Summary
- High thermal capacity via TO-220AB flange mount design
- Sensitive gate structure enabling direct microprocessor interfacing
- Robust surge handling capability for inductive loads
Applications
- Industrial motor control systems
- Solid-state relays
- Power supply circuits
Procurement Notes
Verify the specific suffix 'WTP' against official Littelfuse documentation to confirm exact packaging and reel specifications. Ensure the component meets required RoHS compliance standards for the target assembly process. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.
Selection Notes
Select this component when a 600V blocking voltage and 55A continuous current rating are required in a standard through-hole package. Evaluate the thermal resistance of the mounting interface to ensure the junction temperature remains within the specified operational limits under full load conditions.
Part Context
This part belongs to the Littelfuse Teccor series of silicon-controlled rectifiers. These devices are engineered for reliable performance in demanding power control environments. The series offers various voltage and current ratings to suit diverse industrial and consumer electronic switching requirements.
Replacement Considerations
Compatible substitutes include the S6055R and S6055MTP from the same manufacturer family. Verify that alternative packages maintain equivalent thermal performance and pinout compatibility for direct board replacement.
