(1) Subgroups are applicable for QML parts. For subgroup definitions see Section 6.6.
(2) See the 5962R23203 SMD for additional information on the QML RHA devices. 
(3) PD is the internal power dissipation. When PD exceeds 3W, the current is lowered to avoid excessive local heating (due to tester limitations).
