ACST310-8FP Overvoltage protected AC switch Datasheet production data Description The ACST310-8FP belongs to the ACS / ACST power switch family built with A.S.D. (application specific discrete) technology. This high performance device is suited to home appliances * or industrial systems and drives loads up to 3 A. 287 &20 % 2 )3 7 This ACST310-8FP switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described Features in the IEC 61000-4-5 standard.The component AC switch with self over voltage protection needs a low gate current to be activated (I max. GT 10 mA) and still shows a high electrical noise Microcontroller direct driven (low gate current immunity complying with IEC standards such as max. 10 mA) IEC 61000-4-4 (fast transient burst test). It Three quadrants (Q1, Q2 and Q3) provides UL certified insulation rated at 2000 UL94-V0 qualified resin (flammability) V (file ref: E81734). RMS Complies with UL standards UL1557 Figure 1. Functional diagram Insulated voltage: 2000 V RMS 287 ECOPACK2 compliant component Benefits Enables equipment to meet IEC61000-4-5 High immunity against fast transients * described in IEC61000-4-4 standard Needs no external overvoltage protection &20 High off-state reliability power device Interfaces directly with the microcontroller Table 1.
