The MX1N8158 is a TVS (Transient Voltage Suppressor) diode typically used in a Circuit Protection application. This two-terminal, 5.0 volt device is packaged in a SOT-23 package and uses the Schottky diode principle to protect circuit components from high voltage transients and spikes.

In a circuit protection application, the MX1N8158 is connected in parallel with the protected circuit. The diode\'s anode is connected to the source node and the cathode is connected to the output node. When a high voltage transient occurs, the MX1N8158 will break down, providing a low resistance path that will divert the transient to ground, thus protecting the input circuitry. The protection afforded by the MX1N8158 is always active regardless of the state of the circuits it is protecting.

The diode\'s breakdown voltage for both unidirectional and bidirectional transient protection depends on the circuit configuration as well as the current flowing through the diode. The device also includes a built-in current limitation that helps prevent over current conditions. The built-in current limiter is typically designed to allow currents up to 20A.The device has a built-in thermal fuse that will cut the device off in case of an over current situation.

The MX1N8158 is designed to protect circuits from transients up to + 5V. The diode can also withstand transients up to ± 16V. The device\'s maximum peak power dissipation rating is 220mW, and its minimum operating temperature is 40°C.

The MX1N8158 has a wide range of applications including automotive and industrial, as well as consumer applications. In automotive and industrial applications, the diode can be used to help protect sensitive electronic circuits from voltage spikes caused by wiring, lightning and electrostatic discharge. In consumer applications, it can be used to protect against surges in power, such as those produced by lightning or power line noise.

In summary, the MX1N8158 is an invaluable device for protecting circuits from transient voltage and power surges. It works on the principle of providing a low resistance path to ground when a high voltage transient occurs, protecting the input circuitry. The device also includes built-in current limitation and a thermal fuse which helps protect the circuit from over current conditions. The device can withstand transients up to + 5V and is suitable for a wide variety of applications.
