1.5SMC22A-E3/9AT TVS - Diodes Application Field and Working PrincipleThe 1.5SMC22A-E3/9AT is a Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic components from overvoltage transients. It is one of many TVS - Diodes available in the market. This article will explore the application field and working of the 1.5SMC22A-E3/9AT model.A TVS diode is a protect circuit device that is primarily used to protect voltage sensitive components from potentially damaging over-voltage transients caused by Electro-magnetic Interference (EMI). Overvoltage can occur during surges of power from sources such as lightning, static electricity, or inductive load switching. The 1.5SMC22A-E3/9AT TVS diode is designed to protect sensitive electronics from these surges of power. The 1.5SMC22A-E3/9AT offers 6.5V of protection, with a maximum surge peak current rating of 500A. This is suitable for many off-board applications, such as automotive, computer, and communication systems. The device has an operating temperature range of -65 to +150 °C, which is sufficient for most environments.The 1.5SMC22A-E3/9AT is designed with a Zener diode that is connected in parallel with a silicon avalanche diode. This combination creates a low-impedance path for current when transient voltages occur. When a surge of current attempts to pass through, the avalanche diode switches on to provide a low-resistance current path and the Zener diode prevents excessive voltages from entering the components.In automotive applications, the 1.5SMC22A-E3/9AT is often used to protect the infotainment system from such surges. It is also often used in computer systems to help protect against power surges and other over-voltage events. Additionally, the device can be used to protect external components in communication systems.The 1.5SMC22A-E3/9AT TVS diode is a reliable and effective tool for protecting components from overvoltage transients. It is designed with a Zener diode and an avalanche diode, and offers 6.5V of protection with a maximum surge peak current rating of 500A. It is suitable for applications in automotive, computer, and communication systems, and is capable of operating in temperatures ranging from -65 to +150 °C. With its compact size and high surge current rating, it is an ideal choice for protecting sensitive electronics from overvoltage transients.
