Overview
The Littelfuse S8065KTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx65x series, designed for high-power switching applications. It features an RMS on-state current rating of 65 A and a maximum repetitive peak off-state voltage of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package. Key electrical characteristics include a forward voltage drop of 1.8 V, a gate trigger voltage of 2 V, and a gate trigger current of 50 mA. It supports a non-repetitive peak on-state current of 950 A and maintains a holding current of up to 80 mA.
Feature Summary
- High thermal stability with operation up to +125°C
- Robust surge handling capability for industrial loads
- Standardized SMTO-218 through-hole mounting
Applications
- Solid-state relays
- Industrial motor control systems
- Power supply circuits
Procurement Notes
Verify the specific suffix 'KTP' against the official Littelfuse datasheet to confirm pinout orientation and packaging details. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.
Selection Notes
Select this component when an 800V blocking voltage and 65A continuous current capacity are required in a standard through-hole form factor. Verify that the application's gate drive circuit can supply at least 50 mA to ensure reliable triggering. Confirm that the thermal management design accommodates the power dissipation associated with the 1.8 V forward voltage drop under load conditions.
Part Context
The S8065KTP belongs to the Teccor Sxx65x family of SCRs, which are engineered for general-purpose high-current switching. This series is widely utilized in industrial environments where robust performance and standardized packaging are necessary. The device complements other components in power conversion and control architectures requiring reliable thyristor-based switching solutions.
Replacement Considerations
Consult Littelfuse official substitution guides for compatible alternatives. Verify that any replacement matches the 800V voltage rating, 65A current capacity, and SMTO-218 package dimensions to ensure mechanical and electrical compatibility.
