Description
The EL301X, EL302X and EL305X 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.

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,
τ
RC
is recorded and the dv/dt
calculated.
