S6065KTP

Overview

The Littelfuse S6065KTP is a silicon-controlled rectifier (SCR) from the Teccor Sxx65x series, designed for high-power switching applications. It features an electrically isolated SMTO-218 package suitable for through-hole mounting. The device supports a rated repetitive off-state voltage (VDRM) of 600 V and conducts an RMS on-state current (It RMS) of 65 A. Key electrical parameters include a maximum non-repetitive peak on-state current of 950 A, a forward voltage drop (Vf) of 1.8 V, and a gate trigger voltage (Vgt) of 2 V with a gate trigger current (Igt) of 50 mA. The component operates within a temperature range of -40°C to +125°C and exhibits a holding current (Ih) of up to 80 mA.

Feature Summary

• Electrically isolated construction allows for low-cost assembly and convenient packaging techniques by isolating the case or tab.
• Glass-passivated junctions provide a rugged barrier against contamination, ensuring long-term reliability and parameter stability.
• High surge capability enables the device to withstand significant transient currents without failure.

Applications

• Industrial motor control systems requiring robust half-wave rectification.
• AC power control circuits utilizing gate-triggered switching.
• General-purpose high-current rectification in isolated environments.

Procurement Notes

Verify the specific suffix 'TP' against the official Littelfuse datasheet to confirm package type and compliance status. Ensure the selected variant matches the required isolation specifications and thermal management needs for the target application. Cross-reference manufacturer part numbers to avoid confusion with similar series components.

Selection Notes

Select this component when a 600 V blocking voltage and 65 A continuous current rating are required in an isolated package. Consider the 50 mA gate trigger current for driver compatibility. Evaluate thermal dissipation requirements given the 1.8 V forward voltage drop at full load. Compare against other Sxx65x variants if different voltage ratings or package styles are needed.

Part Context

The S6065KTP belongs to the Littelfuse Teccor Sxx65x family of thyristors. This series offers devices ranging from 1 A to 70 A with voltages from 200 V to 1000 V. The Sxx65x designation indicates a 65 A current rating. These SCRs complement sensitive gate devices and are characterized by glass passivation for durability in demanding electronic controls.

Replacement Considerations

Direct replacements within the same series include S6065JTP (400 V rating) or S8065KTP (800 V rating), provided the voltage margin is adjusted accordingly. Verify that substitute parts maintain the same SMTO-218 package and isolation characteristics to ensure mechanical and electrical compatibility.
