Overview
The Littelfuse S6055RTP is a Silicon Controlled Rectifier (SCR) belonging to the Teccor Sxx55x series. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 55 A. The device utilizes a TO-220-2 through-hole package with a flange mount configuration. Key electrical parameters include a maximum gate trigger current of 40 mA, a forward voltage of 1.8 V, and a holding current maximum of 60 mA. It operates within a temperature range of -40°C to +125°C and exhibits a low off-state leakage current of 10 µA.
Feature Summary
- High current handling capability suitable for robust power control applications
- Low gate trigger current requirement for efficient drive circuit integration
- Robust thermal performance supporting operation in elevated temperature environments
Applications
- Industrial motor speed control systems
- AC power regulation circuits
- Lighting dimmer implementations
Procurement Notes
Verify the specific voltage rating variant required for the design, as the S6055RTP is specified at 400 V, which differs from other members of the Sxx55x family that may offer higher voltage ratings. Confirm package compatibility and ensure the procurement documentation matches the exact Littelfuse part number to avoid substitution errors with similar high-current SCRs.
Selection Notes
Select this component when a 400 V blocking voltage and 55 A continuous current capacity are required in a standard TO-220-2 footprint. Consider the 40 mA gate trigger threshold for driver selection. Ensure the application environment stays within the specified -40°C to +125°C operating range and that adequate heat sinking is provided for the 55 A load.
Part Context
The S6055RTP is part of the Littelfuse Teccor Sxx55x series of silicon controlled rectifiers. This series is designed for general-purpose AC power switching. The 'RTP' suffix typically denotes the specific voltage rating and packaging style within the broader 55 A current class lineup offered by the manufacturer.
Replacement Considerations
The S6055R is a confirmed substitute option within the same product family, offering identical 55 A current handling but with a 600 V voltage rating. Verify that the higher voltage rating of the S6055R does not conflict with system constraints and that the pinout remains compatible.
