Description
The ELM302X series and ELM305X series are optically isolated triac driver devices. These devices contain a
GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a 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

Figure 8. 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, RC is recorded and the dv/dt calculated.
For example, VPEAK = 400V for EL302X series. The dv/dt value is calculated as follows:
