t(delay), t(f) versus I
The triac driver’s turn on switching speed consists of a
turn on delay time t(d) and a fall time t(f). Figure 9 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
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.
