Abstract

PURPOSE: To increase the IH of region A by dividing the main current path of a SCR into region B large in holding current IH, and region A large in di/dt by large (α) in an ignition time and appropriate in external impedance after the ignition.
CONSTITUTION: While the gate circuit opens, almost all current between electrodes 7 and 6 is caused to bypass via short emitter 13, and region B does not work effectively, so that holding corrent IH will be large. As layer 13 becomes more, IH increases. Since a current flowing through the nE layer of region A close to gate electrode 12 acts effectively, IH is small. Therefore, supplying gate current (ig) enable the device ignite with a slight (ig) and to obtain high di/dt dielectric strength. After the ignition, although the gate signal output is made "0", almost all current of region A bypasses to electrode 12 because of impedance 15. The IH of this part is made larger than that of region B by adjusting impedance 15. In this way, high di/dt rating and large IH can be both obtained
