Fast Symmetrical Gate Turn-Off Thyristor type H0700KC17#

2.5 Gate trigger characteristics.

These are measured by slowly ramping up the gate current and monitoring the transition of anode current

and voltage (see diagram 7). Maximum and typical data of gate trigger current, for the full junction

temperature range, is given in the curves of figure 6. Only typical figures are given for gate trigger voltage,

however, the curves of figure 1 give the range of gate forward characteristics, for the full allowable

junction temperature range. The curves of figures 1 & 6 should be used in conjunction, when considering

forward gate drive circuit requirement. The gate drive requirements should always be calculated for lowest

junction temperature start-up condition.

2.6 Turn-on characteristics

The basic circuit used for turn-on tests is given in diagram 8. The test is initiated by establishing a

circulating current in T_x, resulting in V_Dappearing across C_c/L_c. When the test device is fired C_c/L_c

discharges through DUT and commutates T_xoff, as pulse from C_c/L_cdecays the constant current source

continues to supply a fixed current to DUT. Changing value of C_c& L_callows adjustment of I_TMand di/dt

respectively, V_Dand i are also adjustable.
