• AC/DC Motor Controllers: Thyristors are also being used in controlling the speed of AC/DC motors.
• Heating Controllers: TISP4115H3BJR-S can be used in industrial and home appliances, like ovens, heating ovens, hot plates etc.
• Light Controllers: It can be used in controlling halogen lamps, Xenon lamps, UV curing lamps, LED arrays and other lighting sources.

Working principle of TISP4115H3BJR-S

The working principle of thyristors depends on their capacitive forms. As it is constructed with two P-N junction diodes, under no-voltage conditions, the voltage across the two junctions will be reverse-biased and the thyristor will remain non-conducting. When a positive pulse is applied to the gate that is greater than the breakdown voltage of the P-N junction, current from the gate will flow through the gate-cathode path thus allowing the thyristor to remain in the conducting condition. This is known as forward-bias conduction.

This allows the TISP4115H3BJR-S to remain in a conducting state. When the power supply is shut-off or removed, the current flows through the thyristor device reduces to the holding current and hence the device turns off. The TISP4115H3BJR-S also has many advantages like high power dissipation, high efficient switching, high current handling and very low on-state voltage drop.

Conclusion

The TISP4115H3BJR-S is a kind of thyristor, which is a kind of control device and a type of semiconductor switch that can be used in a wide range of applications, like power control, AC/DC motor controllers, heating controllers, and light controllers. The working principle of thyristors is based on their capacitive forms, and the low on-state voltage drop can offer high efficient switching and high current handling capabilities.
