Thanks to its high sensitivity (IGT max = 10 mA), the ACST310 can be driven directly by logic level circuits through a resistor as shown on the typical application diagram (Figure 15). Figure 15.

In addition, the ACST310 is a sensitive device (IGT max. 10 mA), but provides a high noise immunity level against fast transients. The ACST310 switch can safely withstand AC line transient voltages either by clamping the low energy spikes, such as inductive spikes at switch off, or by switching to the on state (for less than 10 ms) to dissipate higher energy shocks through the load. This safety feature works even with high turn-on current ramp up. The test circuit of Figure 17 represents the ACST310 application, and is used to stress the ACST310 switch according to the IEC 61000-4-5 standard conditions. With the additional effect of the load which is limiting the current, the ACST310 switch withstands the voltage spikes up to 2 kV on top of the peak line voltage. The protection is based on an overvoltage crowbar technology. The ACST310 folds back safely to the on state as shown in Figure 18. The ACST310 recovers its blocking voltage capability after the surge and the next zero current crossing. Such a non-repetitive test can be done at least 10 times on each AC line voltage polarity. 8/14 DocID027577 Rev 2 ACST310-8FP Application information Figure 17.

The intrinsic immunity of the ACST310 is shown by the specified dV/dt equal to 1000 V/μs at 125 °C. This immunity level is 5 to 10 times higher than the immunity provided by an equivalent standard technology Triac with the same sensitivity. In other words, the ACST310 with IGT = 10 mA has immunity comparable only for higher gate current device (IGT higher than 35 mA). 10/14 DocID027577 Rev 2 ACST310-8FP 3 Package information Package information • Epoxy meets UL94-V0 • Halogen free molding compound • Lead-free package • Recommended torque: 0.4 to 0.6 N·m In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK® packages, depending on their level of environmental compliance.
