T7SH0840B4DN

Thyristors - SCRs, or silicon controlled rectifiers, are electronic semiconductor components that act as switches for the control of a variety of processes. The T7SH084B4DN is a type of SCR specifically designed for high power or high current applications. It is a sensitive gate pulse SCR with a surge current capability of 90A, with an average current handling capability of 25A. This type of SCR is often used in applications involving thermal, power control, and power management.

The basic working principle of an SCR is the concept of an electrical switch controlled by a gate. When a suitable voltage is applied to the gate, it triggers two currents to begin flowing across two p-n junctions (rectifier), creating a triangular wave that causes the SCR to turn off. When the voltage reaches a certain level, the SCR turns "off" again, and the cycle begins again.

The T7SH084B4DN SCR is usually coupled with a solid-state reset switch and power supply, as well as a circuit breaker and fuses. The device is typically used in areas such as industrial power control, machine automation, in line power control, chemical processing, and electric furnace/smelter control. It is also ideal for use in circuits where high surge current must be handled.

The T7SH084B4DN component can effectively manage power and thermal applications, thanks to its ability to manage a wide range of currents and temperatures. Its electrical characteristics include a maximum repetitive peak current of 90A, a peak on-state voltage of 500V, a maximum surge current of up to 2.5kA, and an insensitive-gate voltage range of 4.8 to 12V. It is suitable for operation at temperatures of -40° to 125°C.

The T7SH084B4DN is a valuable component for applications where high surge currents must be handled. While its surge current capability is impressive, it can also be applied to a variety of other applications, such as power control, thermal management, machine automation, and chemical processing. The device is also attractive due to its wide range of currents, temperatures and voltage ranges, making it an ideal component for many different types of applications.
