Overview
The Littelfuse S8035JTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx35x series, designed for phase control applications. It features an 800 V rated repetitive off-state voltage and supports a 35 A RMS on-state current. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package with internal isolation. Key electrical parameters include a maximum gate trigger current of 40 mA, a forward voltage of 1.8 V, and a holding current of 50 mA. It offers a non-repetitive peak surge current capability of 500 A.
Feature Summary
- Internally constructed isolated package design facilitates ease of heat sinking while providing high isolation voltage.
- Standard phase control characteristics enable triggering with low gate current and potential.
- Robust construction supports high surge currents suitable for industrial power tools and appliances.
Applications
- AC solid-state switches
- Industrial power tools
- Exercise equipment
- White goods and commercial appliances
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package and thermal specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the Littelfuse part number with authorized distributor catalogs to validate availability and lead times. Ensure the selected component matches the required isolation voltage ratings for the target application safety standards.
Selection Notes
Select this SCR for unidirectional phase control circuits requiring 800 V blocking capability and 35 A continuous current handling. The low gate trigger current simplifies driver circuit design compared to higher-power alternatives. Consider the SMTO-218 package dimensions for PCB layout and heatsinking requirements. Evaluate the thermal resistance and junction temperature limits to ensure reliable operation under expected load conditions.
Part Context
This component belongs to the Littelfuse Teccor Sxx35x series of standard SCRs. The series is characterized by its suitability for general-purpose AC switching and motor speed control applications. The S8035JTP variant specifically denotes the 800 V rating and 35 A current capacity within this standardized product line.
Replacement Considerations
Consult Littelfuse official substitution guides for compatible SCRs with matching voltage and current ratings. Verify pinout compatibility and package dimensions before replacing with alternative manufacturers' parts. Ensure equivalent thermal and electrical performance characteristics are maintained in the new component.
