It is also suitable for use in automotive industry, home appliances, and consumer electronics application.

Working Principle

The TISP4250M3LM thyristor is an ideal switching element for low current switch applications. The thyristor works when a gate circuit turns it on when the voltage between the anode and cathode reaches a certain level. The gate has a control current of 0.2A and a startup voltage of 1V. Once it is turned on, the thyristor will remain on until the voltage between the two terminals drops to zero.

When the thyristor is turned on, the charge carriers in the thyristor semiconductor material will start to move and will generate a voltage drop. This generated voltage drop will continue until the voltage at the gate junction and anode junction becomes equal. The current will then stop flowing and the thyristor will turn off. When the current stops flowing, the device will enter the resting state and remain in this state until the gate current allows it to be turned on again. The thyristor will continue to obey this on-off cycle until the input frequency and gate current reach zero.

The TISP4250M3LM thyristor is also designed with a built-in over-voltage protection feature to protect the device from electrical overload. This thyristor is over-voltage fuse rated and offers an excellent protection against excessive voltage. The device also provides excellent thermal shock resistance and can operate at temperatures up to 150 degrees Celsius.
