Component

MOVvaristor460 VAC615 VDC20Dsurge protectionradial lead

VDR-20D751K is a 460 VAC radial MOV intended for transient suppression where its 1240 V clamp at 100 A and 255 J single-pulse energy rating are suitable.

Best for

  • Transient suppression on high-voltage AC or DC circuits
  • Power-input and industrial-electronics protection

Avoid if

  • Required continuous voltage exceeds 460 VAC or 615 VDC
  • Surge energy or current exceeds the specified pulse capability
  • Application requires a confirmed lifecycle or supply status

Check before use

  • 1240 V maximum clamp is specified at 100 A with an 8/20 µs waveform
  • Derate voltage, surge current, energy, and power above +125 °C
  • Use coordinated overcurrent protection where required
