1 k potentiometer
To measure gate trigger voltage and current, raise gate
voltage (VGT) until meter reading V1 drops from 6 V to 1
V. Gate trigger voltage is the reading on VGT just prior to
V1 dropping. Gate trigger current IGT Can be computed
from the relationship.
IGT = IG- - VGT /1000 A
where IG is reading (in amperes) on meter just prior to
V1 dropping.
2. IGT may turn out to be a negative quantity (trigger
current flows out from gate lead). If negative current
occurs, IGT value is not a valid reading. Remove 1 k
resistor and use IG as the more correct IGT value. This will
occur on 12 µA gate products.

9. Design Considerations
Careful selection of the correct component for the
will go a long way toward extending the operating life
of the Thyristor. Good design practice should limit the
maximum continuous current through the main
terminals to 75% of the component rating. Other
ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection
of voltage ratings for worst case conditions.
Overheating, overvoltage (including dv/dt), and surge
currents are the main killers of semiconductors.
Correct mounting, soldering, and forming of the leads
also help protect against component damage.
