Key Features
- 275 V RMS maximum working voltage covers standard 230 V AC mains with sufficient margin for nominal line fluctuations up to ±20%
- 115 J maximum energy absorption capacity handles heavy-duty surge events such as lightning-induced transients on AC power lines per IEC 61000-4-5
- Radial through-hole disk package (14 mm body, 16.5 mm length, 20 mm height) fits standard PCB drill patterns for easy manual or automated insertion
Applications
MOV-14D431K is designed for transient overvoltage suppression on 230 V AC mains inputs in industrial power supplies, home appliances, motor drives, and building automation equipment. Its high 115 J energy rating makes it suitable for primary-side protection in AC-DC converters and line filters where occasional high-energy surges from switching loads or nearby lightning strikes must be clamped before reaching sensitive downstream components.

Frequently Asked Questions
What is the maximum RMS voltage and energy rating of MOV-14D431K, and which AC mains voltage does it suit?
MOV-14D431K is rated for a maximum circuit RMS voltage of 275 V and can absorb up to 115 J of surge energy per event. The 275 V rating makes it directly suitable for 230 V AC mains protection in European and international equipment, providing a comfortable margin above the nominal 230 V line while clamping dangerous transients before they reach rectifiers or capacitors.
How does the 14 mm disk package of MOV-14D431K affect PCB layout compared to smaller MOV packages?
The MOV-14D431K body is 14 mm in diameter, 16.5 mm in package length, and 20 mm in height, requiring a PCB footprint with lead pitch matched to the radial disk package. Compared to 7 mm or 10 mm disk varistors, the larger 14 mm body accommodates more zinc oxide material, which directly delivers the higher 115 J energy rating—a tradeoff of board space for surge handling capability in AC line filter designs.
What surge current can MOV-14D431K handle, and how is this relevant for lightning protection standards?
As a 14 mm body MOV in Bourns' MOV series, the MOV-14D431K is designed to handle peak surge currents typical of 8/20 µs waveform tests per IEC 61000-4-5 Level 3 and Level 4, where transient currents can reach several kiloamps for a few microseconds. The 115 J energy capacity corresponds to sustained clamping during multiple surge events, meeting the requirements of industrial equipment safety standards such as IEC 60950 and UL 1449.
What is the factory lead time for MOV-14D431K, and should procurement teams plan buffer stock?
Bourns lists a factory lead time of 13 weeks for MOV-14D431K, which is significantly longer than commodity components and reflects the specialized zinc oxide disk manufacturing process. Design teams targeting production in less than 4 months should place orders at design freeze or maintain a minimum of 4 to 6 weeks of buffer stock to avoid supply disruptions in AC power line protection circuits.
