TISP3350H3SL

Thyristors have been a popular type of semiconductor device throughout the modern era of electronics. They are used as switches, power regulators, and other important devices. The TISP3350H3SL is a specific type of thyristor that has become increasingly popular in recent years due to its wide range of applications and good efficiency. In this article, we will look at the application field of the TISP3350H3SL and its working principle.

The TISP3350H3SL is a high power turn-off thyristor. Thyristors are devices that are activated by a control signal, and once these devices are activated they remain in a conducting state until either the control signal is removed or the power supply is interrupted. The TISP3350H3SL is designed to be used in high-power applications such as AC motor drives, UPS systems, battery charging systems, and industrial power controls. The device has an impressive peak current rating of 150A and a rated avalanche energy of 4 Joules, making it ideal for applications where overcurrent protection is required. The device has a gate control current of 5mA, indicative of good turn-off efficiency.

The TISP3350H3SL is also equipped with a soft-start feature, which allows the device to gradually increase its current output over time. This feature helps to reduce stress on the system while starting up as well as on the thyristors themselves. The soft-start feature is further enhanced by the device’s excellent transient voltage suppression, which helps to protect against voltage spikes and transients. As such, the TISP3350H3SL is an ideal device for high power and potentially hazardous applications.

The working principle of the TISP3350H3SL is quite simple. When the device is in an inactive state, no gate current is supplied. When a control signal is applied, the gate current is supplied, which causes a small current to flow through the gate junction, resulting in a voltage drop across the gate junction. This voltage drop is detected by the device, which then turns on its output, allowing current to flow from the anode to the cathode. The device remains on until the gate current is removed or the output voltage is interrupted.

To summarize, the TISP3350H3SL is a high power, turn-off thyristor used in a wide range of applications. The device has a peak current rating of 150A and a rated avalanche energy of 4 Joules, making it suitable for applications that require overcurrent protection. The device is also equipped with a soft-start feature and excellent transient voltage suppression for further protection and convenience. The working principle of the device is straightforward and involves a control signal inducing a voltage drop across the gate junction which results in the output being turned on.
