Current commutation:
The values 100 A/ms with following peak reverse recovery current >80 mA should
not be exceeded.
Avoiding high-frequency turn-off current oscillations:
This effect can occur when switching a circuit. Current oscillations which appear
essentially with inductive loads of a higher winding capacity result in current com-
mutation and can generate a relatively high peak reverse recovery current. The fol-
lowing alternating protective measures are recommended for the individual
operating states:
1—Apply a capacitor to the supply pins at the load-side.

Note:
Measures 2 to 3 are especially required for the load separated from the IL410 during oper-
ation. The above mentioned effects do not occur with IL410 circuits which are connected to
the line by transformers and which are not mechanically interrupted.
In such cases as well as in applications with a resistive load the corresponding protective
circuits can be neglected.
