TVS (Transient Voltage Suppressor) Diodes are an important type of diode used for protecting electronic circuits from voltage surges. They are used in a wide range of applications, from high-end industrial equipment to consumer electronics.The SA28AG is a popular model of TVS diode, designed by Bourns, Inc., a leading manufacturer of semiconductors. It is a low power P-channel MOSFET based TVS diode, designed to provide protection against over voltage conditions of up to 28V.The SA28AG is capable of blocking high frequency transients up to 80Amps peak pulse power and 10kA surge current. It also features extremely high surge capability (up to 5.5kA at 10/1000μs), low clamping voltage (23V typical) and fast response time (2.75ns typical).The SA28AG is used in a wide variety of applications, such as industrial, automotive, consumer electronics, and communications circuits. It can be used to protect circuits from high-voltage transients due to lightning strikes, ESD (electro-static discharge), and EFT (electrical fast transient) events. In automotive applications, it is often used to protect sensors, controllers, and other related electronics from the high-voltage fluctuations caused by the power supply.The SA28AG works by sensing an overvoltage condition and conducting current in the reverse direction, which quickly clamps the voltage to a safe level. This ensures that the circuit is protected from any potentially damaging voltage spike. The SA28AG has a low internal resistance, which ensures that it is able to conduct large amounts of current in a single operation.In addition, the SA28AG features a diode gate which ensures that no current is allowed to flow until the voltage reaches a certain pre-set level. This ensures that the TVS diode will not conduct until the voltage reaches an excessive level, thus preventing any unnecessary or accidental switching.Overall, the SA28AG is an ideal solution for providing high-reliability, over voltage protection for a wide range of applications. Its low profile, compact size, and fast response time make it an attractive alternative to more expensive, high power TVS diodes. Its wide operating range, high surge capability, and reliable performance make it a suitable choice for use in a variety of situations.
