Notes : 1. VCONT = 0, IBRT adjusted for having IOUT DC = 50mA outside of BLK.

2. This parameter is not tested in production but is guaranteed by the design and qualify by means of corner lots during the

qualification of the product in SGS-THOMSON. This parameter is measured on a AC testing board as described in Figure 2.
