Littelfuse Thyristor SCR 400 V, 65 A Rated Current, 50 mA Gate Trigger Current, 950 A Surge Current S4065JTP

Littelfuse S4065JTP is a solid-state Silicon-Controlled Rectifier (SCR) Thyristor designed for industrial and electronic power control applications. It supports phase control by switching with low gate currents, making it ideal for use in heating systems, motor speed regulation, and other phase angle control scenarios.

This SCR is housed in a TO-218 package and features a rated average on-state current of 65 A with a surge current capability of 950 A. It has a repetitive peak reverse voltage of 400 V, making it robust for a variety of AC power control functions.

The device’s sensitive gate requires a trigger current as low as 50 mA allowing for precise and reliable switching with minimal input power. Its maximum gate voltage is 2 V and it maintains stable conduction with a holding current of 80 mA. The peak on-state voltage drop is only 1.8 V which contributes to efficient power delivery with reduced losses.

The operating temperature range from -40°C to 125°C ensures suitability in diverse environments including industrial and commercial electronic equipment. The through-hole mount package type facilitates secure and straightforward mounting on printed circuit boards.

Typical applications include phase control in heating elements, motor controllers, power regulators, and other devices requiring controlled switching of AC power. Phase control SCR for heating and motor speed control. Low trigger current gate facilitates efficient switching.

High surge current rating for transient load handling. Robust voltage and current ratings for industrial applications. Wide operating temperature range for diverse environments. TO-218 through hole package suitable for PCB mounting.
