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.

Current commutation:
The values 100 A/ms with following peak reverse recovery current >80 mA should
not be exceeded.
Avoiding high-frequency turn-off current oscillations:
This effect can occur when switching a circuit. Current oscillations which appear
essentially with inductive loads of a higher winding capacity result in current com-
mutation and can generate a relatively high peak reverse recovery current. The fol-
lowing alternating protective measures are recommended for the individual
operating states:
1—Apply a capacitor to the supply pins at the load-side.

Note:
Measures 2 to 3 are especially required for the load separated from the IL410 during oper-
ation. The above mentioned effects do not occur with IL410 circuits which are connected to
the line by transformers and which are not mechanically interrupted.
In such cases as well as in applications with a resistive load the corresponding protective
circuits can be neglected.
