What are the key features of ACS108-6SA-AP?
- 600V off-state blocking voltage for direct AC mains interface in 120V and 230V applications
- 450mA RMS on-state current with sensitive gate trigger as low as 5mA for direct logic-level control
- TO-92 through-hole package with single alternistor element for bidirectional AC switching in all 4 quadrants
What is ACS108-6SA-AP used for?
The ACS108-6SA-AP is designed for microcontroller-driven AC load switching in home automation, thermostat relay replacement, and small appliance control circuits where a logic-level gate signal must switch 600V AC loads without an intermediate driver IC. Its 450mA current rating and sensitive gate make it ideal for lamp dimmers, fan controllers, and low-power motor soft-start applications operating from 50Hz or 60Hz mains.

Frequently Asked Questions
What gate trigger current does the ACS108-6SA-AP require, and can a 3.3V microcontroller GPIO drive it directly?
The ACS108-6SA-AP has a sensitive gate requiring as little as 5mA trigger current at the minimum gate voltage of approximately 0.8V. A 3.3V GPIO sourcing 5mA through a 470-ohm series resistor can reliably trigger all 4 quadrants, making opto-isolator or driver IC stages unnecessary in many low-power designs below 450mA load current.
How does the 600V rating of ACS108-6SA-AP compare to the 800V ACS108-6SA, and when should each be selected?
The ACS108-6SA-AP is rated at 600V repetitive peak off-state voltage, providing roughly 1.85x margin over 230V AC peak (325V), while the ACS108-6SA offers 800V. Choose ACS108-6SA-AP for 120V AC applications with cost-sensitive BOM; choose the 800V variant when 230V mains, surge transients above 600V peak, or IEC 61000 line-surge compliance margins are required.
What is the maximum RMS current the ACS108-6SA-AP can switch, and which load types are within its 450mA rating?
The ACS108-6SA-AP handles up to 450mA RMS on-state current, sufficient for resistive loads up to about 50W at 120V AC or 100W at 230V AC. Inductive loads such as small transformer primaries, relay coils up to 10VA, and low-wattage fan motors fall within this 450mA rating when peak inrush is managed with a series NTC thermistor or soft-start control.
What package does ACS108-6SA-AP use, and how does it compare in board footprint to SMD triac alternatives?
The ACS108-6SA-AP is housed in a TO-92 through-hole cylindrical package with 3 leads on a 1.27mm pitch, occupying a PCB hole pattern of approximately 2.54mm x 1.27mm. Compared to SMD D-PAK or SOT-223 triacs of similar rating, the TO-92 requires more board height clearance (about 5mm) but simplifies hand-soldering and prototype rework in low-volume production runs.
