ACS110 belongs to the AC line switch family built around the ASD™ concept. It is a high-performance switch that can control a load up to 1A. The ACS™ switch has 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. No external protection snubber or varistor is needed, reducing component count. It interfaces directly with the microcontroller and allows straightforward connection of several ACS™ on the same cooling pad (SOT-223).
The ACS110-7SN/SB2 is a high-performance AC line switch from the ASD™ family designed for controlling low power inductive or resistive loads up to 1 A. It integrates a high voltage clamping structure to absorb inductive turn-off energy and a gate level shifter driver, eliminating the need for external protection components like snubbers or varistors.
The device supports blocking voltages of +/-700V and avalanche controlled voltages of 1100V. It is available in SOT-223 and DIL-8 packages and interfaces directly with microcontrollers, enabling straightforward connection of multiple units on the same cooling pad.
| Blocking voltage | +/-700V |
|---|---|
| Avalanche controlled voltage | 1100 V |
| Nominal conducting current | 1A |
| Gate triggering current | < 10 mA |
| Static dV/dt | >500V/us |
| RMS on-state current (SOT-223) | 1 A |
| Non repetitive surge peak on-state current | 8 A |
| Operating junction temperature range | - 30 to+125 °C |
It is well adapted to washing machines, dishwashers, tumble driers, refrigerators, water heaters, air-conditioning systems, microwave ovens, and other cookware.
No, it does not require external protection snubber or varistor because it embeds a high voltage clamping structure.
The critical rate of rise of off-state voltage is a minimum of 500 V/us.
