DESCRIPTION
The IL4208 consists of a GaAs IRLED optically coupled to a photosensi-
tive non-zero crossing TRIAC network. The TRIAC consists of two
inverse parallel connected monolithic SCRs. These three semiconduc-
tors are assembled in a six pin 0.3 inch dual in-line package, using high
insulation double molded, over/under leadframe construction.
High input sensitivity is achieved by using an emitter follower pho-
totransistor and a cascaded SCR predriver resulting in an LED trigger
current of less than 2 mA (DC).
The IL4208 uses two discrete SCRs resulting in a commutating dV/dt
greater than 10 KV/µs. The use of a proprietary dv/dt clamp results in a
static dV/dt of greater than 10KV/µs. This clamp circuit has a MOSFET
that is enhanced when high dV/dt spikes occur between MT1 and MT2
of the TRIAC. When conducting, the FET clamps the base of the pho-
totransistor, disabling the first stage SCR predriver.
The 800V blocking voltage permits control of off-line voltages up to
240VAC, with a safety factor of more than two, and is sufficient for as
much as 380VAC.
The IL4208 isolates low-voltage logic from 120, 240, and 380 VAC lines
to control resistive, inductive, or capacitive loads including motors, sole-
noids, high current thyristors or TRIAC and relays.
Applications include solid-state relays, industrial controls, office equip-
ment, and consumer appliances.
