SA11AG

TVS, commonly known as Transient Voltage Suppressors, is an active protection component that is commonly used in modern electronic applications. It has a broad range of applications including DC-DC converters, mobile phones, laptop computers, consumer electronics and industrial applications. This article looks at the SA11AG TVS component, its field of application and its working principles.

The SA11AG is a unidirectional, lightning-fast bipolar TVS diode designed to protect vulnerable semiconductors from voltage transients caused by lightning, switchmode transients, electrostatic discharges and other similar events. It is available in two packages, a solderable, molded DO-208 package and a standard DPAK package. The do-208 package has a working voltage rating of 7.2V, while the DPAK package has a working voltage rating of 6.2V.

The SA11AG is suitable for a broad range of industrial applications such as automotive, telecommunications, battery charging systems, consumer electronics and portable applications. It is also suitable for applications where board space is at a premium, such as notebook computers. The device is also suitable for use in other general-purpose electronic equipment.

The SA11AG is designed with a special surge current handling capability and wide operating temperature range of -55 to +125ºC. The device has a low reverse leakage current and a fast response time of 1ns. The device is also designed to be immune to short-term overloads.

The working principle of the SA11AG is based on the principle of reverse breakdown. When a voltage greater than its rated voltage is applied across the component, it triggers a ‘reverse breakdown’ which redirects the voltage away from the circuit, protecting it from damage. The device is also designed to shunt away the current, preventing any further damage to the circuit.

The SA11AG provides an effective low impedance protection solution for systems against transient overvoltages. The device operates within a current ratings range of 5A at Peak Pulse Power (PPP) and up to 8A I(pp).It also features a very low stand-off voltage of 1.3V, minimizing the power dissipation. It is also RoHS compliant and UL 94V-0 and JEDEC Moisture Sensitivity Level (MSL) Level Rated.

In conclusion, the SA11AG TVS is a unidirectional, ultra-fast protective surge device suitable for a wide range of electronic applications. Its fast response time, high power handling capabilities and wide operating temperature range make it an ideal choice for protecting circuits from transient overvoltages.
