ILQ621GB - Optocoupler

Download the ILQ621GB datasheet PDF. This datasheet also covers the ILQ621 variant, as both devices belong to the same optocoupler family and are provided as variant models within a single manufacturer datasheet.

General Description

The ILD621/ILQ621 and ILD621GB/ILQ621GB are multi-channel phototransistor optocouplers that use GaAs IRLED emitters and high gain NPN silicon phototransistors.

These devices are constructed using double molded insulation technology.

This assembly process offers a withstand test voltage of 7500 VDC.

Key Features

  • Alternate source to TLP621-2/-4 and TLP621GB-2/-4.
  • High collector emitter voltage, BVCEO = 70 V.
  • Dual and quad packages feature: - Lower pin and parts count - Better channel to channel CTR match - Improved common mode rejection.
  • Isolation test voltage, 5300 VRMS.
  • Lead (Pb)-free component.
  • Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC AGENCY.
