TVS - Diodes

TVS diodes, also known as Transient Voltage Suppressors (TVS), are a special type of diode that is designed to protect a wide range of electronic devices, both active and passive, from transient overvoltage conditions. They are used in a variety of applications such as power supplies, RF/microwave modules, data interface cards, automotive ECU modules, and home entertainment appliances. When exposed to a high-voltage transient, such as a fast-rising voltage coming from a power line or from an electrostatic discharge, the diode will be automatically activated and will conduct current between its two terminals. This action helps to protect the circuit from damage.The SMDA15C-4E3/TR7 is a TVS diode that can be used in a wide range of applications. It is designed to protect sensitive electronic circuits from overvoltage transients up to 8kV. The device has an IEC 61000-4-2 (ESD) protect level of +/- 15kV, and also meets the requirements of UL1449 (4th edition). It has a maximum operating temperature of +125°C and a maximum reverse voltage of 6.5V. The SMDA15C-4E3/TR7 is designed to safely clamp any transient voltage spikes, such as ESD, to a safe level so that the system can continue to operate without any further damage. It has a low response time of just a few nanoseconds, and the clamping voltage is adjustable depending on the application. It also features a low holding voltage which allows it to reduce power consumption and provide higher levels of protection. The working principle of the SMDA15C-4E3/TR7 is simple and straightforward. When the input voltage exceeds a certain limit, the TVS diode will be automatically activated and will conduct current between its two terminals, thus clamping the voltage and preventing further damage to the system. The diode is designed so that it can be easily integrated into a variety of applications, including power supplies, data interfaces, and automotive ECU modules. The SMDA15C-4E3/TR7 can provide protection from fast transients of up to 8kV, and has a low response time of only a few nanoseconds. The device is designed to be easy to integrate into existing systems, and provides a reliable level of protection that is not easily matched by other types of diodes. Its adjustable clamping voltage makes it suitable for a wide range of applications, and its low holding voltage further reduces power consumption. Overall, it is a great choice for applications that require fast and reliable protection from voltage transients.
