Frequently Asked Questions
What surge energy can the V250LA40AP absorb and how does that compare to typical MOV requirements for AC mains protection?
The V250LA40AP absorbs up to 130J of transient energy, which exceeds the typical 10J to 40J requirement for basic appliance AC mains protection and is sufficient to handle the energy of a standard 8/20µs lightning current pulse per IEC 61000-4-5. This 130J rating provides a comfortable safety margin for industrial equipment on 230V or 120V AC lines subject to repeated surge events.
Which AC line voltages are compatible with the V250LA40AP, and can it be used on both 120V and 230V mains?
The V250LA40AP is rated for 250V RMS maximum continuous operating voltage, making it compatible with both 120V AC (North American) and 230V AC (European/international) single-phase mains when connected line-to-neutral. For 230V applications it operates at roughly 92% of its rated voltage, which is acceptable, while for 120V systems it provides significant derating margin and enhanced long-term reliability.
How large is the V250LA40AP disk package and what PCB hole pitch does it require?
The V250LA40AP has a disk body measuring 23mm in diameter and 26.5mm in height with radial leads spaced to fit a standard 7.5mm or 10mm lead pitch depending on the lead form, making it compatible with common through-hole PCB footprints used for 20mm and 25mm varistor disks. Its physical size allows adequate creepage and clearance distances for mains-connected boards designed to IEC 60950 or IEC 62368 safety standards.
When should a designer choose the V250LA40AP over a smaller 14mm disk MOV for an industrial power supply input stage?
A designer should select the V250LA40AP over a smaller 14mm disk MOV when the application demands energy absorption above roughly 40J to 60J, such as in industrial motor-drive input stages exposed to repeated switching transients or environments with high lightning activity. The larger 23mm disk body of the V250LA40AP stores and dissipates 130J per event, reducing the risk of thermal runaway and premature failure that smaller MOVs with lower joule ratings would face under repeated stress.
