• When switching a resistive load (DC1) having voltage and current values under the curve, an electrical life of ≥ 100 · 103 can be expected.

• In the case of DC13 loads, the connection of a diode in parallel with the load will permit a similar electrical life as for a DC1 load.

Note: the release time of the load will be increased.
