TVS - Diodes are a type of general application diodes designed to protect valuable electronics from catastrophic damage. They are commonly used in sensitive circuits to guard against noise, power surges, and electrostatic discharges (ESD).

SMC5K12A-M3/H Application Field and Working Principle

The SMC5K12A-M3/H TVS - Diode is a unidirectional transient voltage suppression (TVS) diode designed for ESD and lightning surge protection of sensitive electronics. It is designed to protect data lines from high-voltage transients while allowing a low-voltage signal to pass through without causing significant attenuation. The device is available in an industry-standard SOD-323 package, and can be used in a variety of applications, including I/O lines protection, power cables ESD/EMI protection, DC/DC converter voltage clamping, and power-supply lines protection.

The TVS diode works based on a property known as reverse breakdown voltage. When an electric current passes through the diode, the voltage across the diode will increase until it reaches the breakdown voltage. At this point, the electric current will flow in a reverse direction and surge protection will be provided.

When working as a TVS diode, the SMC5K12a-M3/H offers a low reverse breakdown voltage, typically between 10V and 15V, as well as a low capacitance and a high power dissipation rating. It also has a low clamping voltage, a fast response time, and a wide operating temperature range. Additionally, the device is RoHS compliant and AEC-Q101 qualified.

The SMC5K12A-M3/H is a highly efficient diode that offers an excellent protection level while still passing a low-voltage signal through. It is a cost-effective solution to ESD and surge protection in a variety of applications, and its industry-standard SOD-323 package makes it an attractive option for system designers.
