Active Solid-state Devices (e.g., Transistors, Solid-state Diodes) > Regenerative Type Switching Device (e.g., Scr, Comfet, Thyristor) > With Light Activation > With Electrical Trigger Signal Amplification Means (e.g., Amplified Gate, "pilot Thyristor", Etc.) With Electrical Trigger Signal Amplification Means (e.g., Amplified Gate, "pilot Thyristor", Etc.)With Electrical Trigger Signal Amplification Means (e.g., Amplified Gate, "pilot Thyristor", Etc.) patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.05/31/07 - 20070120145 - Gate turn-off thyristor A mesa-type wide-gap semiconductor gate turn-off thyristor has a low gate withstand voltage and a large leakage current. Since the ionization rate of P-type impurities greatly increases at high temperatures when compared with that at room temperature, the hole implantation amount increases and the minority carrier lifetime becomes longer. Consequently, ... 03/15/07 - 20070057279 - Light-emitting element having pnpn-structure and light-emitting element array A light-emitting element including a light-emitting thyristor and a Schottky barrier diode is provided. A Schottky barrier diode is formed by contacting a metal terminal to a gate layer of a three-terminal light-emitting thyristor consisting of a PNPN-structure. A self-scanning light-emitting element array may be driven at 3.0V by using ... 03/08/07 - 20070051972 - Thyristor with recovery protection A main thyristor (1) has a recovery protection which is integrated into a drive thyristor (2) whose n-doped emitter (25) is electrically connected to a main thyristor control terminal (140). Moreover, the p-doped emitter (28) of the drive thyristor (2) is electrically connected to the p-doped emitter (18) of the ... ### FreshPatents.com Support |
