Overvoltage protected AC switch

The ACS110 belongs to the AC line switch family built around the ASD concept. This high performance switch circuit is able to control a load up to 1 A.

The ACS switch embeds a high voltage clamping structure to absorb the inductive turn off energy and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.

Key Features

  • Blocking voltage : VDRM / VRRM = +/-700V
  • Nominal conducting current : IT(RMS) = 1A
  • Avalanche controlled : VCL typ = 1100 V
  • High noise immunity : static dV/dt >500V/µs
  • Switch integrated driver
