S8035KTP

Overview

The S8035KTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx35x series, manufactured by Littelfuse. It features an RMS on-state current of 35 A and a rated repetitive peak off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package. Key electrical parameters include a maximum gate trigger current of 40 mA, a holding current of 50 mA, and a forward voltage drop of 1.8 V at rated current.

Feature Summary

• Standard phase control SCR designed for AC solid-state switching applications
• Internally constructed isolated package facilitates heat sinking with high isolation voltage
• Low gate trigger requirements enable efficient control circuitry

Applications

• AC solid-state switches
• Industrial power tools
• Exercise equipment
• White goods and commercial appliances

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm package type and compliance status. Ensure the selected variant matches the required voltage rating and thermal management specifications for the target application environment.

Selection Notes

Select this component for phase control applications requiring 35 A continuous current handling. Confirm that the 600 V blocking voltage aligns with the system's peak line voltage. Verify that the gate drive circuit can supply the specified trigger current and voltage levels reliably.

Part Context

This part belongs to the Teccor Sxx35x series of standard SCRs. These devices are engineered as unidirectional switches for heating and motor speed control circuits. The series offers robust performance in industrial and consumer appliance environments.

Replacement Considerations

Cross-reference with other Sxx35x series variants or equivalent 35 A/600 V SCRs from Littelfuse. Verify pinout compatibility and thermal resistance values before substituting.
