EL817S

4 PIN SDIP4 PHOTOTRANSISTOR PHOTOCOUPLER

Description

The EL817 series contains a infrared emitting diode optically coupled to a phototransistor. It is

packaged in a 4-pin DIP package and available in wide-lead spacing and SMD option.

Applications

• Computer terminals

• System appliances, measuring instruments

• Registers, copiers, automatic vending machines

• Signal transmission between circuits of different potentials and impedances

Features:

• Current transfer ratio

(CTR:MIN.50% at IF =5mA ,VCE =5V)

• High isolation voltage between input

and output (Viso=5000 V rms )

• Compact dual-in-line package
