1.5SMC480A, commonly referred to as TVS, is a transient voltage suppression diode, which is used to protect electrical circuits from electrostatic discharge or high voltage transients. It is designed for direct connection between an electrical power source and the protected component. The 1.5SMC480A prevents voltage transients from causing damage to circuits while allowing current to flow normally.

The working principle of the 1.5SMC480A is based on the idea of a voltage clamp - a device that can quickly reduce the voltage of a signal to a certain value. When a high voltage transient or surge is detected, the 1.5SMC480A immediately begins to reduce the voltage to a preset level. This reduces the amount of current that would normally be allowed to flow, thereby preventing damage to the protected component.

The 1.5SMC480A is suitable for a variety of applications. It can be used to protect computers, communications equipment, consumer electronics, and automotive systems from electrical damage caused by power supply transients, lightning strikes, or static electricity. Its wide operating temperature range and fast response make it an ideal solution for protecting sensitive electronic components from voltage transients.

At the heart of the 1.5SMC480A is a top cathodic trigger device, a variant of SCR or thyristor. This device rapidly conducts when triggered by a surge current, allowing current to flow through the device and reduce the voltage. The 1.5SMC480A also features integrated current limiting, reverse polarity protection, and short circuit current limiting to protect against over-current conditions.

The 1.5SMC480A has a variety of features that make it an ideal solution for protecting against over-voltage or current conditions in electrical systems. It has a low on-state resistance, meaning it is less likely to degrade the performance of the protected device. Its fast response time and low surge current ratings make it suitable for applications requiring fast transient protection. Its wide operating temperature range and integrated current limiting features also make it an ideal choice for protecting against high voltage transients.

The 1.5SMC480A is a cost-effective solution for providing transient voltage protection for electrical systems. It is designed for quick and easy installation and provides reliable protection against transient voltage surges. It is suitable for a wide range of applications, from consumer electronics to automotive systems, and provides fast and reliable protection against over-voltage or current conditions.
