MOVs

MOVvaristorradial lead7 mm disc25 VAC31 VDCsurge protection

V39ZA1P is a 7 mm Littelfuse radial MOV for transient suppression on circuits up to 25 VAC or 31 VDC. It provides 79 V maximum clamping at 2.5 A and a 250 A 8/20 µs surge-current rating.

Best for

  • Transient suppression on 25 VAC or 31 VDC circuits
  • Motor-control, telecom, solenoid, and power-supply protection

Avoid if

  • The protected circuit cannot tolerate up to 79 V clamping at the specified test current
  • Surge energy or repetitive pulse loading exceeds the qualified rating curves
  • Continuous voltage exceeds 25 VAC RMS or 31 VDC

Check before use

  • Validate clamping voltage at the actual surge current
  • Apply temperature derating above 85 °C ambient
  • Check MOV degradation and end-of-life protection strategy
