ILQ621 - MULTI-CHANNEL PHOTOTRANSISTOR OPTOCOUPLER

General Description

The ILD/Q621 and ILD/Q621GB are multi-channel phototransistor optocouplers that use GaAs IRLED emitters and high gain NPN silicon phototransistors.

These devices are constructed using over/under leadframe optical coupling and double molded insulation technology.

Key Features

  • Alternate Source to TLP621-2/-4 and TLP621GB-2/-4.
  • Current Transfer Ratio (CTR) at IF= 5 mA ILD/Q621: 50% Min. ILD/Q621GB: 100% Min.
  • Saturated Current Transfer Ratio (CTRSAT) at IF=1 mA ILD/Q621: 60% Typ. ILD/Q621GB: 30% Min.
  • High Collector-Emitter Voltage, BVCEO=70 V.
  • Dual and Quad Packages Feature: - Reduced Board Space - Lower Pin and Parts Count - Better Channel to Channel CTR Match - Improved Common Mode Rejection.
  • Field-Effect Stable.
