V39CH8T is a 39 V nominal Littelfuse CH Series SMD MOV for transient suppression, with 25 VAC / 31 VDC continuous ratings and 79 V maximum clamping at 5 A.

Best for

  • Board-level transient suppression
  • Low-voltage DC rails within 31 VDC continuous operation
  • Space-constrained SMD surge protection

Avoid if

  • The normal line voltage can exceed 25 VAC RMS or 31 VDC
  • The circuit cannot tolerate the MOV clamping voltage
  • Substantial repetitive average power dissipation is expected

Check before use

  • 79 V maximum clamping voltage at 5 A
  • 1.0 J 10/1000 µs single-pulse energy rating
  • 100 A 8/20 µs peak-current rating
  • Soldering thermal-gradient and reflow-profile limits
