The STA07220 is a medium-voltage bidirectional two-quadrant voltage controlled switch. The STA07220 device combines many of the features associated with voltage-controlled relays, but in a single-package form. This switch offers lower cost of installation and maintenance without compromising reliability, switching speed or noise suppression. The STA07220 device can be used in a variety of applications, ranging from linear regulated power supplies to surge protection systems.

The STA07220 is especially suitable for application in motor control, adjustable speed drives, soft starter drives, single-phase power supplies, automotive and marine auxiliaries, and lighting/electronic ballast controls. This device has excellent power dissipation and low source-to-drain switching times, allowing its use in repeat switching or voltage-controlled power devices. Current limiting, current monitoring, and voltage monitoring features are included in the STA07220 device, making it a complete package for power supply control and protection.

The working principle of the STA07220 is simple yet effective. The device functions as a voltage-controlled switch, allowing a voltage-controlled resistor or other devices to be switched on or off with the application of a voltage. The integrated protection features make it an optimal choice for motor control applications. When a voltage is applied to the control input, the device switches on and off according to the magnitude of the input voltage. When the voltage reaches the switching level, the device switches on and off, allowing the power to be switched on and off without the need for a separate on-off switch.

The STA07220 also offers an ideal solution for surge protection applications. The integrated surge protection feature protects circuits from transients generated by induction motors, allowing users to have a reliable protection solution without compromising performance. With its safety features and ease of use, the STA07220 is the perfect choice for any application requiring voltage-controlled switching.

The STA07220 is an excellent choice for many applications because of its cost-efficiency, reliability, and protection features. It integrates well with other power devices, providing a straightforward solution to power supply control, protection, and current monitoring. The device is also suitable for switching power supplies, lighting applications, and motor control applications. There are many advantages in using the STA07220 device; its universal applicability, low source-to-drain switching times, low cost, and robust performance make it the best choice for many applications.
