Testing method for parameters

7/9

Appendix A

Testing method for parameters

The testing method for IDRM / IRRM parameters is:

●

Apply the specified VDRM or VRRM voltage across anode and cathode (or A2 and A1

terminals for TRIACs, or OUT and COM terminals for AC Switches)

●

Measure the leakage current peak value: it must be less than the maximum

specification value (IDRM / IRRM max.).

It is forbidden to use a current supply and apply the IDRM / IRRM max. through anode

and cathode, and then measure the voltage.

In this case, the TRIAC or the SCR goes into breakdown voltage and may be damaged.

Note:

A voltage higher than the VDRM / VRRM rated values may be applied for less than 10 ms if it

does not exceed the VDSM / VRSM parameters specified in the device datasheet.
