TVS (transient voltage suppression) diodes, such as the MQ1N8159US, are designed to protect circuits from electrical transients or surges. They are semiconductor devices that divert or clamp excessive voltages away from delicate electrical components. This type of diode is designed to be used in both AC and DC applications and is available in various form factors and values.

The MQ1N8159US is a unidirectional TVS diode with an extended voltage rating of 600W. It has a peak Pulse Power (PPP) of 1500W, which makes it suitable for protecting electronic equipment against damaging spikes or surges of electricity. The reverse stand-off voltage (VRWM) of the diode is 15V. It has an ESD (electrostatic discharge) rating of 18kV and an eye-diagram rating that meets IEC 61000-4-2 level 4 standard.

TVS diodes work by two main principles of operation: clamping and diverting. Clamping is where the diode is designed to clamp, or reduce the voltage to a certain predetermined level. This level is usually determined by the reverse stand-off voltage of the diode. Diverting is where the diode is designed to divert, or shunt excess voltage away from sensitive electronic components or circuitry. By diverting voltage, the diode effectively reduces the amount of energy that is lost in the incident surge, protecting components from damage, and limit the possibility of system or component failure.

The MQ1N8159US TVS diode can be used in a variety of applications where overvoltage protection is required, such as AC/DC, DC/DC, and audio circuits. It can also be used in automotive, telecommunications, industrial, and consumer electronics applications.

Since TVS diodes like the MQ1N8159US provide excellent protection from voltage spikes and surges, they are ideal for protecting sensitive components from loosely regulated power sources. By using these diodes, circuit designers can ensure that the delicate and mission-critical components installed in such circuits are protected from power surges and voltage spikes. This prevents the system from suffering unnecessary damage and ensures reliable operation.
