Thyristor TRIZ Cases

A bypass thyristor device incorporates a gas expansion volume within its housing to manage high currents.

Embeds a monitor circuit in the seal ring to detect dielectric deformation via electrical changes.

A field-stop reverse conducting insulated gate bipolar transistor uses polysilicon filling structures in the active region to manage current flow.

Segmented doped regions in the substrate redirect ESD current to increase holding voltage and protect integrated circuits.

Independent gate electrodes manage carrier discharge to reduce turn-off loss while maintaining low on-resistance in the semiconductor device.

Applying a higher potential to the anode gate conducts an internal diode, evacuating holes to reduce turn-off time while maintaining voltage rating.

Adjustable trigger and holding voltages in bipolar or SCR devices manage overvoltage conditions across multiple ranges while minimizing substrate area.

Varying gate electrode trench depths prevent latch-up in IGBTs by managing electric fields and blocking parasitic transistor currents.

Current diffusion layers concentrate flow in light-emitting thyristors, eliminating unwanted shift thyristor emission that degrades image contrast.

An impulse current generator uses a thyristor crowbar circuit to bypass tail currents during surge protection device testing.

Higher doped spreading layers under blocking junctions lower reverse leakage current while maintaining forward voltage levels.

Setting the pitch between 1/40 and 1/20 of the base layer thickness reduces on-voltage while maintaining manufacturing precision.

Segmented trench structure in clustered insulated gate bipolar transistors balances switching speed and conduction loss.

A thyristor ESD structure uses a low-resistance coupling between collector and anode regions to enhance holding voltage.
