The TISP4350M3LM is a 400V, 1700 V peak inverse voltages (PIV) sensitive gate triggering thyristor with ultra-fast triggering. Thyristors are a type of semiconductor device that acts as a switch which can be triggered to conduct when exposed to certain levels of voltage. They are commonly used in industrial applications because they can handle high power (currents up to hundreds of amperes) and are relatively low cost. The TISP4350M3LM is designed for use in motor control, electronic lighting, DC power supplies, and similar applications.

The TISP4350M3LM features a sensitive gate that requires a very small voltage to trigger the thyristor into conduction. This is important in applications where the voltage vary over time or where a small input signal is available. The thyristor has a turn-on time of 75nS and a turn-off time of 15µs, making it suitable for high power applications where rapid switching is required. The device also features good thermal stability and low power dissipation.

The TISP4350M3LM is designed to operate as a static switch in air and low-pressure environments, meaning that it can be triggered on and off without needing continual input. This makes it suitable for use in applications where the presence of gas or other environmental factors can interfere with other types of thyristors. The device is also capable of handling currents of up to 17A, making it suitable for powering high-power loads such as motors or lights.

As with other thyristors, the TISP4350M3LM can be triggered to conduct using either positive or negative gate voltage. This allows it to be used in both AC and DC applications. When triggered, the device will remain in a conducting state until the current through the device drops below a certain level or the device receives a negative gate voltage. The device is also fully reversible, meaning that it can be switched between conducting and non-conducting states multiple times each cycle.

Overall, the TISP4350M3LM is an ideal choice for use in applications where high power is required and fast switching is desired. Its sensitive gate allows it to be triggered by small signals, while its robust construction and wide voltage and current ratings make it suitable for use in both indoor and outdoor applications. With low power dissipation and thermal runaway protection built in, the TISP4350M3LM is a highly reliable device for use in both commercial and industrial applications.
