IL410-X001隔離器的光隔離器-雙向可控硅SCR輸出規(guī)格書PDF中文資料

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 VAC, with a safety factor of more than

two, and is sufficient for as much as 380 VAC.

The IL410, IL4108 isolates low-voltage logic from 120 VAC,

240 VAC, and 380 VAC lines to control resistive, inductive, or

capacitive loads including motors, solenoids, high current

thyristors or TRIAC and relays.
