Description
The EL303X, EL304X, EL306X and EL308X series of devices
each consist of a GaAs infrared emitting diode optically coupled to
a monolithic silicon zero voltage crossing photo triac.
They are designed for use with a discrete power triac in the interface of
logic systems to equipment powered from 110 to 380 VAC lines, Schematic
such as solid-state relays, industrial controls, motors, solenoids and
consumer appliances. 1

Figure 10. Static dv/dt Test Circuit & Waveform
Measurement Method
The high voltage pulse is set to the required VPEAK value and applied to the D.U.T. output side through the RC
circuit above. LED current is not applied. The waveform VT is monitored using a x100 scope probe. By
varying RTEST, 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, τRC is recorded and the dv/dt
calculated.
For example, VPEAK = 600V for EL306X series. The dv/dt value is calculated as follows:
