DESCRIPTION
The IL410 consists of a GaAs IRLED optically coupled to a photosensi-
tive zero crossing TRIAC network. The TRIAC consists of two inverse
parallel connected monolithic SCRs. These three semiconductors are
assembled in a six pin 0.3 inch dual in-line package, using high insula-
tion 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 IL410 uses two discrete SCRs resulting in a commutating dV/dt
greater than 10KV/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 zero cross line voltage detection circuit consists of two enhance-
ment MOSFETS and a photodiode. The inhibit voltage of the network is
determined by the enhancement voltage of the N-channel FET. The P-
channel FET is enabled by a photocurrent source that permits the FET to
conduct the main voltage to gate on the N-channel FET. Once the main
voltage can enable the N-channel, it clamps the base of the phototrans-
istor, disabling the first stage SCR predriver.
The 600V 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 IL410 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.
