Overview
The S2055MTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series manufactured by Littelfuse. It features a rated repetitive off-state voltage of 200 V and an on-state RMS current rating of 55 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-218 through-hole package. Key electrical characteristics include a maximum breakover current of 650 A, a forward voltage of 1.8 V, and a gate trigger current of 40 mA. The holding current is specified at a maximum of 60 mA, with an off-state leakage current of 10 uA at VDRM.
Feature Summary
- High current handling capability with a 55 A RMS on-state rating for robust power control applications.
- Low forward voltage drop of 1.8 V contributes to reduced conduction losses during operation.
- Wide thermal operating range supports reliable performance in demanding environmental conditions.
Applications
- Industrial motor speed control systems
- AC power regulation circuits
- Lighting dimmer implementations
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number S2055MTP with official Littelfuse documentation. Confirm that the package type matches the specified TO-218 through-hole configuration. Ensure compliance with RoHS directives as indicated in the product specifications before integration into final assemblies.
Selection Notes
Select this SCR when a 200 V blocking voltage and 55 A continuous current capacity are required. The TO-218 package facilitates standard through-hole mounting techniques. Verify that the gate trigger requirements align with the driving circuit capabilities, specifically noting the 40 mA gate trigger current specification.
Part Context
This component belongs to the Teccor Sxx55x family of SCRs, which provides standardized high-current thyristor solutions. The S2055MTP variant specifically addresses applications requiring lower voltage ratings compared to higher-voltage siblings like the S4055MTP or SK055MTP while maintaining identical current handling and packaging characteristics.
Replacement Considerations
Direct replacements within the same series include S4055MTP (400V), SK055MTP (1000V), and S8055MTP (800V). These alternatives share the same 55 A current rating and TO-218 package but offer different voltage blocking capabilities. Ensure the system voltage does not exceed the replacement device's VDRM rating.
