EL357
Features:
• Current transfer ratio
(CTR:MIN.50% at IF =5mA ,VCE =5V)
• Isolation voltage between input and output
(E357: Viso=3750 Vrms )
• Subminiature type
(The volume is small than that of conventional
DIP type by as far as 30%)
• Mini-flat package
EL357:1-channel type
• Pb free
• The product itself will remain within RoHS compliant version.
Description
The EL357 contains a gallium arsenic infrared emitting diode optically
coupled to a phototransistor. It is packaged in a 4-pin SMD package
Applications
• Hybrid substrates that require high density mounting
• Programmable controllers
• System appliances, measuring instruments
• Telecommunication
• Electric home appliances, such as fan heaters, etc.
• Signal transmission between circuits of different potentials
and impedances
