S2055RTP

Overview

The Littelfuse S2055RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series, designed for phase control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 55 A. The device has a maximum gate trigger current (IGT) of 40 mA and a forward voltage drop (Vf) of 1.8 V at rated current. It operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package.

Feature Summary

Standard phase control SCR with low gate trigger requirements
Glass-passivated junctions for enhanced reliability
High surge capability up to 650 A

Applications

Heating controls
Motor speed controls
Phase control circuits

Procurement Notes

Verify the specific suffix 'RTP' against the official Littelfuse datasheet to confirm tube packaging and exact electrical tolerances. Ensure the component matches the required 400V rating and TO-220-2 form factor for your design. Cross-reference manufacturer part numbers to avoid confusion with similar series variants.

Selection Notes

Select this component when a 55A RMS current handling capacity is required in a standard through-hole configuration. The 400V blocking voltage suits lower voltage AC phase control systems. Verify that the 40mA gate drive current aligns with your triggering circuit capabilities before finalizing the design.

Part Context

This part belongs to the Littelfuse Teccor Sxx55x series of 55 Amp Standard SCRs. These devices are engineered as excellent unidirectional switches for industrial phase control. The series offers voltage capabilities up to 1000V, with this specific model providing the 400V option in a robust TO-220-2 package.

Replacement Considerations

Direct substitutes include other 55A 400V SCRs in TO-220 packages from Littelfuse or competitors, provided they meet the 40mA IGT and 1.8V Vf specifications. Verify pinout compatibility and thermal resistance values before substitution.
