Study Notes
Thyristor Equivalents and Characteristics
- The equivalent of TRIAC is a bilateral switch, which can conduct current in both directions.
UJT Components
- The ratio of RB1 to RBB in a Unijunction Transistor (UJT) is called the intrinsic standoff ratio.
Thyristor Structure
- Thyristors have four PN junctions, which are crucial for their operation.
Thyristor Operation
- The minimum value of anode current below which it must fall to completely turn off the thyristor is called the holding current.
Thyristor Voltage Characteristics
- The forward breakover voltage is the voltage at which the thyristor begins to conduct when the gate is triggered.
