TVS (Transient Voltage Suppressor) diodes are used in a wide range of applications to protect against transient electrical over-voltage and more specifically, power surges. The SMAJ350CA is a unidirectional TVS Diode designed to deliver rated power dissipation (P D ) when the working voltage (V WM ) is sufficiently high. It has an absolute maximum working voltage of 350 Volts (V WM ), a continuous forward current (I F ) of 5 Amps (A), and features a fast response time.

The SMAJ350CA is ideal for protecting sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge and inductive loads. It is also used for power-line protection in communication and industrial equipment, as well as in datacom and telecom applications. It is especially well-suited for unfiltered solid state systems with no ground line.

The SMAJ350CA diode operates in two main modes: (1) clamping mode and (2) current limit mode. In the clamping mode, the device conducts a reverse current and limits the voltage amounts that can exceed the rated clamping voltage any further. This ensures that the protected components remain in their original state, allowing them to function properly. In the current limit mode, the device begins to conduct a forward current when the breakdown voltage is reached, and the current is limited to the clamp current.

The SMAJ350CA is designed with an integrated ESD diode, a low leakage current, and a low capacitance. Its fast response time makes it ideal for applications where transients last for a very short duration such as Electrostatic Discharge (ESD) and Lightning Transients. Additionally, its superior ruggedness guarantees reliable operation in industrial secured and unprotected applications, as well as in commercial applications.

In conclusion, SMAJ350CA is a unidirectional TVS diode designed for efficient and reliable protection of sensitive electronic components from transient electrical over-voltages. It can be used in a wide range of applications such as power-line protection, lightning protection and electrostatic discharge protection. Its fast response time, low leakage current and low capacitance make it an ideal choice for a variety of low- and medium-power applications.
