TVS diodes which stands for Transient Voltage Suppressors, is a type of electronic component used to protect high voltage circuits from power surges. The MPTE-5RL4G is a unidirectional TVS diode which is designed to protect sensitive electronic devices from electrostatic discharge. It is typically used for low frequency protection and is suitable for use in applications with overvoltage transients such as equipment powered from the automotive, telecom or HVAC power supplies.

The MPTE-5RL4G TVS diode is designed with active protection elements which reduce the time needed to suppress over-voltage transients. It is composed of a low-noise diode array with each diode having a built-in avalanche diode and pull-up/pull-down resistors. This helps to reduce the switching time and improves the operating current draw. It also offers protection from electrostatic discharge with a peak pulse current capacity rating of up to 28A.

The MPTE-5RL4G TVS diode is especially suitable for various applications in automotive, telecom, HVAC, industrial and consumer markets. Typical applications include overvoltage protection for transistors and MOSFETs within power supplies and protection of circuit boards from short-circuit currents in high-voltage DC power systems. The diode is also suitable for overvoltage protection for AC and DC power supplies used in portable electronics, computers, medical systems, motor control, and various communications systems.

The MPTE-5RL4G TVS diode is a unidirectional diode, meaning it will only conduct current in one direction and not the other. This type of diode is typically used when the circuit is being operated at AC voltage levels. The diode will then act as a rectifier, allowing current to flow in one direction only and blocking it in the other. It is used to help regulate and protect the circuit from voltage spikes and surges.

The working principle of the MPTE-5RL4G TVS diode is based on the avalanche effect. When an incoming surge or electric field changes, the diode’s intrinsic voltage, which is connected by the junction of two materials, will break down. When this occurs, a large number of electrons will be released from the junction, resulting in a large current. This current will then be distributed over the other components in the circuit, helps to reduce the voltage to a safe level.

The MPTE-5RL4G TVS diode is a reliable and inexpensive overvoltage protection device that can be used in a wide range of applications. Its low noise operation, fast switching and high pulse current capacity make it an ideal choice for sensitive electronic devices such as computers and medical systems. In addition, its compact size and easy installation make it an ideal choice for portable electronics and other applications requiring low voltage overvoltage protection.
