Device summary Symbol Value Unit Description I 10 A T(RMS) The ACST10 series belongs to the ACS/ACST V /V 700 V DRM RRM power switch family built with A.S.D. (application specific discrete) technology. This high I 10 or 35 mA GT performance device is suited to home appliances or industrial systems, and drives loads up to 10 A. This ACST10 switch has a Triac structure and a high voltage clamping device to absorb the inductive turn-off energy and withstand transients such as those described in the IEC 61000-4-5 standard. The ACST1010-7 needs a low gate current to be activated (I < 10 mA) and still GT TM: ACS is a trademark of STMicroelectronics shows a high noise immunity complying with IEC : A.S.D. is a registered trademark of STMicroelectronics 61000-4-4 standard. The ACST1035-7 offers a high static dV/dt immunity of 2 kV/s minimum. July 2010 Doc ID 15237 Rev 3 1/13 www.st.com 13Characteristics ACST10 1 Characteristics Table 2.
