  • For 15V and below operating voltage
  • Excellent capability of absorbing transient surge
  • Bi-directional
  • Quick response to surge voltage (nS)
  • Low clamping voltage
  • Each I/O pin can withstand over 1000 ESD strikes for ±8kV contact discharge

Typical Application


SYS915VBHJC is designed to protect equipments from transients induced by lightning or other transient voltage events. The device will act as a crowbar when overvoltage occurs and will divert the energy away from circuit or device that is being protected.
SYS915VBHJC is in SMB package with working voltage of 15 volts. SYS915VBHJC is a bidirectional device so it is able to have functionality of 2 devices in one package, saving valuable space on board layout.
