The ERZ-E14A431 is an aesthetic, excellent performing over-voltage protection component from American Electrical Components. It belongs to the family of transient voltage surge suppressors (TVS) and offers a wide range of features to protect sensitive circuits and components from over-voltage conditions. These powerful components are also known as varistors, metal oxide varistors (MOVs) and surge protectors. This particular surge protector is designed and used mainly for telecommunications and industrial equipment.

The ERZ-E14A431 is designed to provide over-voltage protection against transients such as lightning, electro-magnetic interference (EMI), motor switching, and static charge. It is available in a plastic 4-pin insulated case with pins connected directly to the solid metal oxide material inside. This efficient surge protector offers high performance in an extremely small package, that is able to fit into very limited or tight spaces.

The rated AC and DC working voltages are 120VAC and 200VDC respectively. The voltage range over which the suppressor is effective is from 145 to 500 Volts AC and from 200 to 630 Volts DC. The maximum surge current is 10KA(10/1000 μs) and the maximum impulse current is 20KA 10/1000. The maximum energy capability of these surge protectors is 0.5J per 3KV per pulse.

These components have a working principle which is based upon the voltage variable resistor (VVR) technology. When a surge or transient enters, the MOV begins to conduct, dissipating the excess energy to the ground. This rapid response time and efficient performance of the ERZ-E14A431 make it an excellent choice for surge suppression applications. The activity of the MOV does not affect the function of the circuit being protected by it.

This type of surge suppressor has a wide range of applications including automotive, consumer, industrial, medical, and telecom sectors. For automotive applications, this surge protector is commonly used on various components such as DC controlled locking systems, window regulators, temperature sensors, fuel pumps, and door locks. In the industrial and medical sectors, it is used in appliance line cords, surgical tools/equipment, and RFID readers/scanners. It is also common in the telecom industry where it can be used in telephone transmission lines, loudspeaker systems, and digital audio systems.

To summarize, the ERZ-E14A431 is a powerful, highly efficient over-voltage protection component which is categorized under the family of Transient Voltage Surge Suppressors (TVS) and is also known as varistors, metal oxide varistors (MOVs) and surge protectors. It has a voltage range of between 145-500VAC and 200-630VDC and is used in a variety of applications including automotive, consumer, industrial, medical, and telecom sectors.
