Detailed content

  • Reverse Standoff Vrwm:​ 1140 V DC
  • Breakdown Vbr:​ 1254–1380 V
  • Clamping Vc:​ 1750 V @ 3.43 A IPP
  • Response Time:​ < 1 ns
  • Package:​ DO-204AA (R-6 axial), glass-passivated
  • Junction Temp:​ −55 °C to +175 °C
Material:​ Diffused silicon chip, ceramic body, epoxy coat, tinned OFC leads.
Working Principle:​ Below 1140 V = open; surge exceeds Vbr → avalanche conducts → voltage clamped near 1750 V → energy dumped to ground.
Application Scenarios:​ Wind converter DC-link, PV inverter 1000 VDC+, VFD DC bus, UPS input surge, turbine exciter 1300 VDC protection.
Installation & Notes:​ Must be parallel to protected rail, leads < 10 mm, near DC terminals; never exceed 1140 V working; check leakage after repeated surges.
