DESCRIPTION
The IL410 and IL4108 consists of a GaAs IRLED optically
coupled to a photosensitive zero crossing TRIAC network.
The TRIAC consists of two inverse parallel connected
monolithic SCRs. These three semiconductors are
assembled in a six pin dual in-line package.
High input sensitivity is achieved by using an emitter
follower phototransistor and a cascaded SCR predriver
resulting in an LED trigger current of less than 2 mA (DC).
The use of a proprietary dV/dt clamp results in a static dV/dt
of greater than 10 kV/ms. 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 phototransistor, disabling the first
stage SCR predriver.
The zero cross line voltage detection circuit consists of two
enhancement 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 phototransistor, disabling the first stage SCR
predriver.
The 600 V, 800 V blocking voltage permits control of off-line
voltages up to 240 V
