Notes
(1) T_amb = 25 , unless otherwise specified.
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability.
(2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through hole devices (DIP).


Description

The ILD621GB 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.

The ILD621GB is well suited for CMOS interfacing given the CTRCEsat of 30 % minimum at IF of 1.0 mA. High gain linear operation is guaranteed by a minimum CTRCE of 100 % at 5.0 mA. The ILD/Q621 has a guaranteed CTRCE 50 % minimum at 5.0 mA. The transparent ion shield insures stable DC gain in applications such as power supply feedback circuits, where constant DC VIO voltages are present.
