Description
The ELM304X, ELM306X and ELM308X devices consist of a GaAs infrared emitting diode optically coupled to a
monolithic silicon detector performing the function of a zero voltage crossing bilateral triac driver.
They are designed for use with a discrete power triac in the interface of logic systems to equipment powered from
110 to 240 VAC lines, such as solid-state relays, industrial controls, motors, solenoids and consumer appliances,
etc.

Figure 10. Static dv/dt Test Circuit & Waveform
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.
For example, V
PEAK
= 600V for EL306X series. The dv/dt value is calculated as follows:
