Optocoupler, Phototransistor Output
(Dual, Quad Channel)
ILD621/ILD621GB/ILQ621/ILQ621GB
Vishay Semiconductors
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.
The ILD621/ILQ621GB is well suited for CMOS interfacing
given the CTR
CEsat
of 30 % minimum at I
F
of 1.0 mA. High
gain linear operation is guaranteed by a minimum CTR
CE
of
100 % at 5.0 mA. The ILD/Q621 has a guaranteed CTR
CE
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 V
IO
voltages are
present.
