S6065JTP

Overview

The Littelfuse S6065JTP is a silicon-controlled rectifier (SCR) from the Teccor line, designed for high-voltage and high-current applications. It features an electrically isolated SMTO-218 package with a glass-passivated junction for reliability. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 65 A. The device supports a non-repetitive peak surge current of 950 A. Gate triggering requirements are specified with a maximum gate trigger voltage (VGT) of 2 V and a maximum gate trigger current (IGT) of 50 mA. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Electrically isolated construction allows the case or tab to be mounted directly to heatsinks without external insulators.
• Glass-passivated junctions provide a rugged barrier against contamination, ensuring long-term parameter stability.
• High surge capability supports demanding transient loads up to 950 A.

Applications

• Industrial motor controls
• Power supply circuits
• Lighting control systems

Procurement Notes

Verify the specific suffix JTP against official Littelfuse documentation to confirm package type and isolation specifications. Ensure the ordered part matches the required voltage and current ratings for the target application. Cross-reference datasheet revisions to confirm compliance with current RoHS standards before finalizing procurement.

Selection Notes

Select this component when a 600 V blocking voltage and 65 A continuous current capacity are required in an isolated package. The SMTO-218 form factor is suitable for through-hole mounting where thermal management via the tab is necessary. Verify that the gate drive circuit can supply at least 50 mA to ensure reliable turn-on under all operating conditions.

Part Context

The S6065JTP belongs to the Littelfuse Teccor SCR series, which offers devices ranging from 1 A to 70 A with voltages from 200 V to 1000 V. This series complements sensitive SCRs by providing higher current handling capabilities while maintaining standard gate sensitivities. The product line emphasizes durability through glass passivation and versatile packaging options for various industrial and commercial electronic designs.

Replacement Considerations

Direct replacements must match the 600 V rating, 65 A current capacity, and SMTO-218 isolated package. Verify that substitute parts maintain equivalent gate trigger characteristics and thermal performance. Consult manufacturer substitution guides for approved equivalents within the same family or competitive offerings with identical pinouts and electrical limits.
