Overview
The Littelfuse S6055MTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series, designed for through-hole mounting in an SMTO-218 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 55 A. The device has a maximum non-repetitive peak on-state current of 650 A and a forward voltage drop (Vf) of 1.8 V. Gate triggering requires a maximum voltage (Vgt) of 1.5 V and current (Igt) of 40 mA. The holding current (Ih) is 60 mA max, with leakage current at 10 uA under VDRM. Operating temperature ranges from -40 C to +125 C.
Feature Summary
- High current handling capability with 55 A RMS rating for robust power control applications
- Robust surge tolerance with 650 A non-repetitive peak current capacity
- Standardized gate drive requirements facilitating easy integration into control circuits
Applications
- Industrial motor speed control systems
- AC power regulation and switching circuits
- Solid-state relay implementations
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number S6055MTP with official Littelfuse documentation. Confirm the SMTO-218 package type and RoHS compliance status match project specifications. Ensure the supplier provides valid traceability records for the Teccor branded thyristor to guarantee performance reliability in critical power electronics assemblies.
Selection Notes
Select this SCR for applications requiring 600 V blocking voltage and 55 A continuous current handling. The SMTO-218 package offers thermal management suitable for moderate power dissipation. Consider the 1.5 V gate trigger voltage when designing the driving circuitry. Compare against other Sxx55x variants if different voltage ratings or package styles are required for specific board layout constraints.
Part Context
This component belongs to the Littelfuse Teccor Sxx55x series of silicon controlled rectifiers. The series provides standardized electrical characteristics across various voltage ratings, allowing designers to swap components within the same current class while adjusting for voltage requirements. The MTP suffix indicates the specific SMTO-218 through-hole packaging configuration used for this 600 V variant.
Replacement Considerations
The S6055RTP is a confirmed alternative offering identical 55 A and 600 V specifications but utilizes a TO-220AB package instead of SMTO-218. Verify mechanical fit and thermal interface compatibility before substitution.
