Note: V1 — 0 V to 10 V dc meter
V
GT

I
G
— 0 mA to 1 mA dc milliammeter
R1 — 1 k potentiometer
To measure gate trigger voltage and current, raise gate voltage
(V
GT
) until meter reading V1 drops from 6 V to 1 V. Gate trigger
voltage is the reading on V
GT
just prior to V1 dropping. Gate trig-
ger current I
GT
can be computed from the relationship
where I
G
is reading (in amperes) on meter just prior to V1 drop-
ping.
Note: I
GT
may turn out to be a negative quantity (trigger current
flows out from gate lead). If negative current occurs, I
GT
value is
not a valid reading. Remove 1 k resistor and use I
G
as the more
correct I
GT
value. This will occur on 12
μ
A gate products.
