IL440
TRIAC PREDRIVER
NON-ZERO CROSSING
OPTOCOUPLER
FEATURES
• 600 V Blocking V oltage
• 7 mA Maximum Trigger Current
• Isolation Voltage, 3750 VAC, t=1 sec.
• Isolation Materials per UL94
APPLICATIONS
• High Current Triac Driver
• Solid State Relays

DESCRIPTION
The IL440 consists of a GaAs infrared emitter optically
coupled to a silicon planar triac chip with a non-zero
crossing network. The two semiconductors are
assembled in a 6 pin dual-in-line plastic package. The
output detector is capable of blocking up to 600 volts
which permits control of off-line voltages up to 240
VAC. The IL440 can handle currents up to 100
mA
