Description
The ELT302X and ELT305X series of devices each consist of a GaAs infrared emitting diode optically coupled to a
monolithic silicon random phase photo Triac.
They are designed for interfacing between electronic controls and power triacs to control resistive and inductive
loads for 115 to 240 VAC operations.
Applications
Solenoid/valve controls
Lamp ballasts
Static AC power switch
Interfacing microprocessors to 115 to 240Vac peripherals
Incandescent lamp dimmers
Temperature controls
Motor controls

Measurement Method
The high voltage pulse is set to the required V
PEAK
value and applied to the D.U.T. output side through the RC circuit
above. LED current is not applied. The waveform V
T
is monitored using a x100 scope probe. By varying R
TEST
,
the dv/dt (slope) is increased, until the D.U.T. is observed to trigger (waveform collapses). The dv/dt is then
decreased until the D.U.T. stops triggering. At this point,
RC
is recorded and the dv/dt calculated.
dv/dt =
0.632 x V

For example, V
