TT61N12KOFHPSA1 Discrete Semiconductor Products

Thyristors are some of the most commonly used semiconductor devices, and are designed with a wide variety of applications. A specific type of thyristor, known as the silicon controlled rectifier (SCR) is one of the most widely used semiconductor devices for controlling power flow. The TT61N12KOFHPSA1 is an SCR module from STMicroelectronics, that is optimized for use in high power applications. This article will discuss the application fields and working principles of the TT61N12KOFHPSA1.

Overview of the TT61N12KOFHPSA1

The TT61N12KOFHPSA1 is a bidirectional SCR module from STMicroelectronics which features an integrated low gate-charge diode. It is designed with a total gate-charge of 170µC, a low onstate voltage drop of 0.55V, 64A on-state current, and a current-controlled turn-off gate to ensure a fast turn-off time. Other features of the TT61N12KOFHPSA1 include its fast turn-on time and its ability to protect against short circuit currents. Additionally, the TT61N12KOFHPSA1 uses a ceramic base which provides enhanced thermal performance in order to increase the product’s life and reliability.

Application Fields

The TT61N12KOFHPSA1 is well suited for applications which require high current and/or high-power operation. Some examples of such applications include industrial heating, electric motors, invertors, AC and DC drives, HVAC, and solar power systems. Additionally, the module can be used in lighting or high-speed switching applications such as those used in welding or in the aerospace industry.

Working Principles

The TT61N12KOFHPSA1 module is composed of two thyristors connected in inverse parallel. A thyristor is a device which uses four independent layers to control current flow, and the TT61N12KOFHPSA1 has two such devices. The module can be used as a switch, allowing current to flow only when a voltage is applied to the gate. When the voltage is removed, the module switches off, stopping current flow. This makes the TT61N12KOFHPSA1 ideal for applications where current flow needs to be quickly and precisely controlled.

The TT61N12KOFHPSA1 also includes a gate-controlled diode to protect against short circuit currents. This diode\'s gate is capable of turning off the device quickly, in order to prevent damage due to current overload. Additionally, the module can detect temperature variations and perform an auto-recovery when needed.

Conclusion

The TT61N12KOFHPSA1 SCR module is an ideal choice for high-power applications. It provides a low gate-charge, low on-state voltage drop, current-controlled turn-off gate, fast turn-on and fast turn-off times, and an integrated low gate-charge diode for protection against short circuit currents. This module is available for applications such as industrial heating, electric motors, invertors, AC and DC drives, HVAC, solar power systems, lighting, and high-speed switching.
