Littlefuse Inc., the global leader in circuit protection, has rolled out a series of 40A standard high-temperature silicon-controlled rectifier (SCR) Thyristors ideally suitable to be used as rectifier switches and phase control applications including a voltage regulator, heating, and motor speed controls.
The new SJxx40x Series is the first SCR Thyristor from Littlefuse that can handle 600V, 40Arms and junction temperature of up to 150°C. It prevents the overheating, as well as thermal runaway problems SCRs, experience due to the limited cooling capability or occasional overload situation. The aim is to trigger with just a few milliamps of current at less than 1.5CV potential.
Coming to the applications, these SCR Thyristors can be used as rectifiers in a variety of end uses like AC solid-state switches, industrial power tools, exercise equipment, white goods and commercial appliances.

• Handles high load current and occasional overloads under limited cooling conditions due to a high junction temperature of 150°C.
• Available in both TO-220AB and TO-263 packages to support flexible mounting options for easier device design.
• High on-state current (IT) of 40Arms allows the SJxx40X to handle higher load currents.
• High Rate of voltage change over time (dv/dt) enables the SJxx40X to tolerate more line noise and surge found in commercial AC lines.
The SJxx40x Series is available in either TO-220AB (non-isolated) or TO-263 (D2-Pak) packaging in quantities of 500 with 50 per tube.
