TVS (Transient Voltage Suppressor) diodes are a type of components that are designed to protect a circuit from overvoltage transients. The 1.5SMC120CAHM6G is one such device specifically designed for high-energy protection against lightning strikes, electrostatic discharges, and other high-voltage transients. In this article, we will discuss the application field and working principle of the 1.5SMC120CAHM6G.

The 1.5SMC120CAHM6G is a three-terminal, bi-directional TVS diode designed to protect electronic equipment from voltage transients. This device is typically used in telecommunication systems, automotive systems, medical systems, and military / aerospace systems. It is also suitable for protecting AC power and DC power supplies from overvoltage transients.

The 1.5SMC120CAHM6G is designed with a reverse standoff voltage of 12V and a maximum peak pulse power rating of 4500W. This TVS diode also features an excellent clamping capability and fast response time. The clamping voltage of the device is around 11.4V when it is used to protect against a 5A voltage transient.

The 1.5SMC120CAHM6G utilizes a special semiconductor structure to provide protection against voltage transients. Its operation is based on the avalanche breakdown principle, which states that when the reverse bias of a PN junction is increased beyond a certain threshold, there will be a sudden increase in current. This current surge causes the diode’s breakdown voltage to drop dramatically, clamping out the transient voltage and protecting the circuit.

The 1.5SMC120CAHM6G has a number of features that make it an ideal choice for overvoltage protection applications. These include its compact design, low leakage current, easy installation, and wide operating temperature range. The device is also RoHS and REACH compliant, making it an environmentally friendly solution.

In summary, the 1.5SMC120CAHM6G is a three-terminal, bi-directional TVS diode designed for high-energy protection against lightning strikes, electrostatic discharges, and other high-voltage transients. It is suitable for protecting AC and DC power supplies, and it utilizes a semiconductor structure to provide protection based on the avalanche breakdown principle. The 1.5SMC120CAHM6G has a number of features that make it an ideal choice for overvoltage protection applications, including its compact design, low leakage current, and wide operating temperature range.
