Overview
The Littelfuse S8055RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series, designed for high-current switching applications. It features an 800 V rated repetitive off-state voltage and handles a maximum RMS on-state current of 55 A. The device utilizes a TO-220-2 through-hole package with flange mounting capabilities. Key electrical characteristics include a forward voltage drop of 1.8 V at rated current, a gate trigger voltage of 1.5 V, and a gate trigger current of 40 mA. It operates within a junction temperature range of -40°C to +125°C and exhibits a non-repetitive peak surge current capability of 650 A.
Feature Summary
- High thermal stability with a maximum operating junction temperature of 125°C
- Robust surge handling capability with a 650 A non-repetitive peak current rating
- Standard recovery type construction suitable for general-purpose AC/DC control
Applications
- Industrial motor control circuits
- Solid-state relay modules
- Power supply regulation systems
Procurement Notes
Verify the specific suffix 'RTP' against the manufacturer's official datasheet to confirm the exact packaging configuration, as this designation typically indicates tape-and-reel or cut-tape availability rather than standard tube packaging. Ensure the ordering part number matches the required lead time and moisture sensitivity level specifications provided in the latest production notice.
Selection Notes
Select the S8055RTP when an 800 V blocking voltage and 55 A continuous current capacity are required in a surface-mount compatible or through-hole form factor. Compare the 1.8 V forward voltage drop against alternative thyristors to evaluate conduction losses. Confirm that the TO-220-2 package dimensions align with the printed circuit board layout and heatsinking requirements for the intended thermal management strategy.
Part Context
This component belongs to the Littelfuse Teccor Sxx55x family of silicon controlled rectifiers. The series is characterized by standardized electrical parameters across different voltage ratings, allowing for design flexibility. The S8055 variant specifically targets the 800 V segment, providing a reliable solution for medium-to-high power electronic switching tasks where robustness and predictable triggering are essential.
Replacement Considerations
Publicly confirmed substitute part numbers for the S8055RTP were not identified in the available documentation. Engineers should consult the manufacturer's cross-reference guide or equivalent product selection tools to identify compatible alternatives with matching voltage, current, and package specifications.
