Thyristors - TRIACs are semiconductor devices that are essentially switches used to control electric current. The L401E8 is a four-layer medium-voltage, planar, deep trench TRIACs with easily connectable control terminals. The device is able to control and regulate the power flow in devices such as pumps, fans and lights, making it well suited to switch applications.

TRIACs are a type of thyristor developed using two SCRs connected in opposite directions, such that two opposite gates can be triggered to turn it off. The L401E8 is a 40A TRIAC, the largest of its kind with a four layer structure. It has an optimized layer structure which enables high-stress breakdown, precise on-state current regulation, and reliable surge capabilities. The device features a wide operating temperature range of -25° to 125°C as well as a high peak operating power rating of 1300V/20,000W.

The L401E8 is designed primarily for applications in surge withstand circuits, and has earned a UL rating of UL60950-1 making it safe to use in many electrical applications. The device is also used in the control and regulation of power flow in pumps, fans, and a variety of electrical appliances. With its easily connectable control terminals, the L401E8 can be used for direct high-side or low-side drive elements.

The working principle of a L401E8 TRIAC involves controlling power using a three-pole switch. When a current passes through two of the terminals, it activates the third. This is known as the main terminal, and can be used to control the switching of the TRIAC. The device has an internal gate which allows it to detect the voltage across the maint terminals and switch accordingly. When the main terminals reach a certain positive or negative voltage, it will turn on and stay on until the current is removed.

The L401E8 also features an accurately controlled on-state current regulation for high-peak load applications. This is done using two high-sensitivity diodes, one of which is connected in series with the main terminal to control the on-state current. The other diode can be connected in series with the control terminal, allowing for precise control of the on-state current.

The L401E8 can be used in a variety of devices, and its easily connectable control terminals make it ideal for applications in high-side and low-side switches, such as pumps and fans. Its wide operating temperature range, high peak operating power rating, and UL rating make it an attractive solution for many design requirements.
