Gate Sensitivity
The
SCR100
attempts to trigger the device under test at nine discrete gate
currents, in ascending order.
Trigger level 1
100
A
Trigger level 2
1mA
Trigger level 3
10mA
Trigger level 4
25mA
Trigger level 5
35mA
Trigger level 6
50mA
Trigger level 7
60mA
Trigger level 8
75mA
Trigger level 9
90mA
As an example, a reported trigger current of 10-25mA means that device
triggering occurred at a gate current of 25mA, but not at 10mA. Therefore the
trigger current for the device under test is between 10mA and 25mA.
Although Triacs are tested in both quadrants 1 and 3, the reported gate trigger
current is that which applies to quadrant 3.
