ACS108-8SP-TR [STMicroelectronics]

The ACS108-8SP belongs to the AC switch range (built with A. S. D. technology). This high performance switch can control a load of up to 0.8 A.

This device switch includes an overvoltage crowbar 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.

• Enables equipment to meet IEC 61000-4-5 surge with overvoltage crowbar technology
• High noise immunity against static dV/dt and IEC 61000-4-4 burst
• Needs no external protection snubber or varistor
• Reduces component count by up to 80% and interfaces directly with the micro-controller
• High creepage distance for SOT223-2L: 3.8 mm
• Clamping at V_CL, then crowbar action
