TVS – Diodes: SM8LC15E3/TR7 application field and working principle

TVS - diodes, also known as transient voltage suppressors, are special types of semiconductor diodes that are designed to protect sensitive electronic equipment from high voltage transients such as those seen during electrostatic discharge (ESD). SM8LC15E3/TR7 is a type of TVS diode that can protect against ESD events ranging from 2kV to 15kV with a response time of less than 1ns. The SM8LC15E3/TR7 is a bidirectional diode, meaning it can protect against ESD events from either direction.The SM8LC15E3/TR7 is mainly used in consumer electronic settings, particularly in machines such as TVs and DVD players where electrostatic discharge protection is essential. The SM8LC15E3/TR7 is also well-suited for use in industrial applications such as electrical installations and automotive applications where ESD protection is required.The working principle of the SM8LC15E3/TR7 is simple. The diode is designed so that when an ESD event occurs, it rapidly clamps the voltage at a safe level before it can damage any sensitive electronics. This is achieved by having two junctions in the diode, one on either side. When a transient voltage is applied to the diode, the voltage on the anode side is clamped by the diode to a voltage below its breakdown rating. This voltage is then clamped again to the VF (forward voltage drop) of the diode on the other side, ensuring that the voltage never exceeds the corresponding maximum safe voltage.The SM8LC15E3/TR7 is a popular choice for ESD protection due to its superior performance and small form factor. The SM8LC15E3/TR7 has a clamping voltage of 18V, a peak pulse power of 270W and a breakdown voltage of 8kV. The device is also very small, measuring a mere 2x2mm.The SM8LC15E3/TR7 is an important asset when it comes to providing reliable ESD protection for consumer electronics as well as industrial applications. Its low cost and small size make it a great choice for many different types of electronic products. With its superior performance and reliability, the SM8LC15E3/TR7 is an indispensable component in any ESD protection system.
