t(delay), t(f) versus I FT
The triac driver’s turn on switching speed consists of a
turn on delay time t(d) and a fall time t(f). Figure 12
shows that the delay time depends on the LED trigger
current, while the actual trigger transition time t(f) stays
constant with about one micro second.
The delay time is important in very short pulsed opera-
tion because it demands a higher trigger current at very
short trigger pulses. This dependency is shown in the
graph I FT vs. LED PW.
The turn on transition time t(f) combined with the power
triac’s turn on time is important to the power dissipation
of this device.
SCOPE
1. The mercury wetted relay provides a high speed
repeated pulse to the D.U.T.
2. 100x scope probes are used, to allow high speeds and
voltages.
3. The worst-case condition for static dv/dt is established
by triggering the D.U.T. with a normal LED input
current, then removing the current. The variable R TEST
allows the dv/dt to be gradually increased until the
D.U.T. continues to trigger in response to the applied
voltage pulse, even after the LED current has been
removed. The dv/dt is then decreased until the D.U.T.
stops triggering. τ RC is measured at this point and
recorded.
