GT Gate trigger voltage is the reading on V just prior to V1 + GT D.U.T. dropping. Gate trigger current I Can be computed from 6V GT DC I IN4001 – GT the relationship IG R1 V1 100 1 k V V GT (1%) GT I = I - ____ Amps GT G 1000 where I is reading (in amperes) on meter just prior to V1 G dropping Note: I may turn out to be a negative quantity (trigger GT current flows out from gate lead). If negative current occurs, I value is not a valid reading. Remove 1 k resistor GT and use I as the more correct I value. This will occur on G GT 12 µA gate products. © 2018 Littelfuse, Inc.
