TVS-diodes, also known as transient voltage suppressors (TVS), are a type of surge protection device (SPD) that is used to protect electronic circuits from damage from transient overvoltages. They are most commonly used in electronic circuits where higher voltages, such as lightning or electrostatic discharge (ESD) spikes, are a potential risk. The TPSMP18AHE3/85A is a TVS-diode that is used for a variety of applications.

The TPSMP18AHE3/85A is a bidirectional diode with a voltage standoff rating of 18 volts. It can handle up to 85 amps of transient current and can dissipate up to 1.5 watts of power. The diode has an operating temperature range of -55°C to +150°C. It is available in an industry-standard SMB package for easy integration into a variety of systems.

The TPSMP18AHE3/85A is most commonly used in automotive systems, industrial systems, and consumer electronics. It can be used for input protection of power supplies, as well as transient protection for sensitive components. In automotive applications, it is commonly used to provide surge protection to electronic control units (ECUs). In industrial systems, it is used to protect sensitive components from power surges and electrical noise. In consumer electronics, it is used to protect sensitive components from ESD and lightning strikes.

The working principle of the TPSMP18AHE3/85A is quite simple. When an overvoltage event, such as ESD or lightning, occurs, the diode will clamp the voltage down to the rated standoff voltage. The diode works by finding the lowest impedance path for the current to flow and dissipating the excess energy as heat. This limits the voltage at the protected component to the rated voltage, and prevents damage from occurring.

In summary, the TPSMP18AHE3/85A is a type of TVS-Diode that is used for a variety of applications. It is most commonly used in automotive, industrial, and consumer electronics systems for surge protection. Its working principle is to find the lowest impedance path for the current to flow and dissipate the excess energy as heat in order to limit the voltage at the protected component. It is available in an industry-standard SMB package and can withstand up to 85 amps of transient current, allowing it to provide reliable protection against overvoltages in a variety of applications.
