ISP620-1XGBG is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISOLTR 5.3KV 1CH TRANS 4-DIP. Review the specifications below when checking this part for your BOM.
The ISP620-1XGBG is a high-density AC input phototransistor optically coupled isolator manufactured by Isocom Components. It features an infrared LED emitter connected in inverse parallel with an NPN silicon phototransistor, enabling polarity-insensitive operation for AC signals. The device provides a high isolation voltage of 5300 VRMS and 7500 VPK between input and output circuits. It is housed in a surface mount package designed for space-efficient applications. All electrical parameters are 100% tested during manufacturing to ensure reliability.
Verify the specific suffix 'GBG' against official Isocom documentation to confirm exact lead frame material, plating finish, and RoHS compliance status. Ensure the selected package variant matches the required PCB footprint and thermal management needs for the target application environment.
Select this component when AC signal isolation is required without additional rectification circuitry. The inverse parallel LED design simplifies driver requirements. Confirm that the phototransistor output characteristics meet the load switching requirements of the downstream circuitry.
This part belongs to the ISP620 series of high-density optocouplers. It serves as a drop-in replacement for industry-standard AC input optocouplers. The series is designed for compact designs requiring reliable galvanic isolation in noisy industrial environments.
Compatible replacements include TLP620-1X, PS2505-1X, and ISP814. Verify pinout compatibility and electrical parameter margins before substitution.
