MOVTP series thermal protected metal oxide varistors from Eaton Electronics are ideal for protecting sensitive components at the circuit board level, providing protection against surges and transients from events such as lightning, power contact, and power induction.
The combination of the metal oxide varistor with a thermal fuse element allows the MOVTP to protect circuits from overvoltage transients while also preventing the device from reaching thermal runaway in the event of a sustained overvoltage event.
The MOVTP varistors are radial leaded devices and come in two or three-pin configurations. The integrated third lead can be used to generate an alarm signal during transient events or product end of life. The MOVTP is offered in 14 mm and 20 mm diameter discs and can withstand peak surge currents from 6,000 A to 10,000 A.
