Optos – overview
Switching amplification
C.92
The phototransistor of the opto has a low current and voltage
rating. As a consequence, an additional semiconductor element
is accessed for larger output loads that is capable of switching
the corresponding rated switching voltages and rated switching
currents.
Bipolar Transistor (DC)
Used for low currents (0.5 A).
The bipolar transistor has short response times, which makes
high switching frequencies possible as a result.
MOSFET (DC)
Used for high load currents (up to 10 A).
The low contact resistance of the MOSFET create only very
small leakage currents (< 10 μA) with low power loss.
TRIAC (AC)
A TRIAC combines the functional principle of antiparallel
connected tyristors in a single component.
The mode of function of a tyristor is comparable with that
of a one-way diode. Therefore, an opposing parallel circuit
configuration consisting of two tyristors is used for AC currents.
