Model SPT402 with Involute gate
.0051
.0034
* double sided cooling
through external copper
post inserts
The SPT402 thyristor features a multi-arm involute gate which can be triggered with 5 - 10 A gate pulses by means of an integrated
pilot gate or directly fired using 50 - 100A gate pulses. The involute pattern affords full area conduction in minimum time while
a corresponding high di/dt rating depends on the choice of gating method. The factory setting for either pilot triggered or gate
triggered version, internal to the package, is an option when ordering by keying it to the model number code. The design utilizes
a new termination technique, SPCO's revolutioary Light Silicon Sandwich, LSS technology, which eliminates heavy refractory
metal as a substrate while retaining the alloyed anode interface necessary for high surge current duty. This thyristor is supplied
in a reliable plastic light weight package allowing the insertion of liquid cooled chillers. Solid copper inserts can be ordered
for adjoining air cooled heat dissipators using commercially available clamping hardware.
