Power Semiconductor Devices

Various types of power semiconductor devices were developed and became comercially available.

These can be divided into four types:

1. Power Diodes
   • General Purpose
   • High Speed
   • Schottky
2. Thyristors
   • Forced-Commutated Thyristor
   • Line-Commutated Thyristor
   • Gate Turn-Off Thyristor (GTO)
   • Reverse Conducting Thyristor (RCT)
   • Static Induction Thyristor (SITH)
   • Gate-Assisted Turn-Off Thyristor (GATT)
   • Light-Activated Silicon-Controlled Rectifier (LASCR)
3. Power Bipolar Junction Transistors (BJT)
4. Power MOSFETs
