DESD12V0S1BL-7B Circuit Protection

DESD 12V0S1BL-7B is a TVS - Diode device, widely used for surge protection. It is a unidirectional component, and can protect against high-voltage spikes in an electronic system. These devices are designed to reduce and protect against damage from heavy lightning storms, power surges and transients, as well as transient signals from outside sources such as induction heating systems and electrostatic discharge.

The DESD 12V0S1BL-7B provides circuit protection for sensitive products and circuits, such as data processors, power supplies, and control systems. It helps protect the system from over-voltage, over-current, and short-circuit as well as from short-duration transient signals. The component also acts as a secondary protection in addition to other circuits and fuses to provide further surge protection.

It features a reverse breakdown voltage of 12V, and is designed to operate on PCBs and supports the anti-surge design protection. It ensures DC fault- tolerance and has a very fast response time, making it suitable for extreme environment situations. The device also offers current-limiting protection, with a peak current of 8A, for a short time and low on-state leakage.

The device consists of a body, an anode, a gate, and a cathode. The body is usually made from a ceramic material such as alumina or silicon nitride. It is connected to the anode with a conductive material, such as tin. The gate is an insulated gate made of a polyimide resin. It is connected to the cathode with a resistor. When a surge is present, the gate passes current to the cathode, which in turn energizes the body, allowing the device to begin operation.

When a surge is present, the DESD 12V0S1BL-7B absorbs the excess energy and dissipates it as heat. This is achieved by the device being capable of a very fast switching time between ON and OFF states. As a result, the device offers exceptional protection, even in extreme environments, such as on systems exposed to lightning and solar flares. The device also has the capability to absorb larger chunks of energy from the grid.

The DESD 12V0S1BL-7B does not require any extra external components to operate, making installation easier. These devices are highly reliable and offer a good thermal performance. They are also less vulnerable to electrostatic discharge when compared to other kinds of protection components. This makes them suitable for use in industrial, military, space and medical applications.

In summary, the DESD 12V0S1BL-7B is a TVS – diode device, designed for surge protection applications. It offers current-limiting protection and low-on-state leakage, with an operating temperature range from -55°C to +175°C. It is designed for PCB mounting and has a fast response time. It is ideal for industrial, military, and space applications, as well as medical devices and protects against surges, transients, power surges, and lightning storms.
