A phototransistor is optically connected to an infrared emitting diode in the EL817 series. It comes in a 4-pin DIP package with wide-lead spacing and an SMD variant.
• Current transfer ratio (CTR:50% at IF=5mA and VCE=5V)
• High isolation voltage (Viso=5000 V rms) between input and output
• EL817*:1-channel compact dual-in-line package
