Thyristors are important power electronic component used in the industries for the control of power flows. Thyristors have found multiple applications in electronics and computing systems for controlling high current and power flow. The TISP4125H3LMFR-S is one of the most commonly used thyristors. This article explains the application field and working principle of this component.

TISP4125H3LMFR-S Application Field

The TISP4125H3LMFR-S is designed for use in motor drives, UPS systems, industrial control, high voltage smps, and other medium and high power applications. It has two main applications-dynamic switching and bidirectional-current rectification. It is an ideal choice for high current, bidirectional current applications such as Bidirectional DC/AC Inverter, Current Rectifier, Motor Control Move, Brushless Motor, and Industrial DC/AC Inverter Replacement.

TISP4125H3LMFR-S Working Principle

The TISP4125H3LMFR-S is a four layer thyristor. It is composed of two antiparallel thyristors connected in series. The two thyristors are connected back-to-back. When voltage is applied to the TISP4125H3LMFR-S, the two thyristors conduct current in both directions (bidirectional current rectification). The TISP4125H3LMFR-S switches from off-state to on-state when the voltage across it exceeds its rated breakdown voltage. When the voltage is removed, the thyristor switches from on-state to off-state.The TISP4125H3LMFR-S is also capable of dynamic switching. Dynamic switching refers to the ability of the thyristor to switch between on-state and off-state states rapidly, thus making it ideal for high frequency switching. The switching time is approximately 300us. This makes it ideal for high speed switching and applications where precise current control is required.

Conclusion

The TISP4125H3LMFR-S is a four layer thyristor designed for use in motor drives, UPS systems, industrial control, high voltage smps and other medium and high power applications. It is capable of bidirectional current rectification and dynamic switching. This makes it an ideal choice for a wide range of applications where current control is needed.
