Notes:
1. Gate control may be lost during and immediately
following surge current interval.
2. Overload may not be repeated until junction
temperature has returned to steady-state
rated value.
Note: V1 — 0 V to 10 V dc meter
VGT — 0 V to 1 V dc meter
IG — 0 mA to 1 mA dc milliammeter
R1 — 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
VGT
IGT = IG- ____ Amps
1000
where IG is reading (in amperes) on meter just prior to V1
dropping
Note: 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.

Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment 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 device
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.
