ISD5 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 2CH TRANS 8-DIP. Review the specifications below when checking this part for your BOM.
The ISD5 is a surface-mount, single-channel optocoupler from Isocom Components featuring an infrared LED and NPN silicon phototransistor. It provides high isolation voltage of 5.3 kVrms (7.5 kVpk) and a minimum collector-emitter breakdown voltage (BVCEO) of 70 V. The device utilizes a space-efficient dual in-line plastic package with options for lead spread, tape-and-reel packaging, or standard surface mount configurations.
Verify the specific suffix required for your manufacturing process. Add 'G' for 10mm lead spread, 'SM' for surface mount, or 'SMT&R' for tape-and-reel packaging. Confirm that the selected variant matches the intended PCB footprint and automated assembly requirements before finalizing procurement.
Select this component when high-density mounting and robust electrical isolation are required. Ensure the application voltage does not exceed the 70 V BVCEO rating. Consider the specific package suffix to align with existing board designs or reflow soldering profiles used in the production line.
The ISD5 belongs to the IS*, ISD*, and ISQ* series of high-density phototransistor optically coupled isolators. These components integrate infrared LEDs with NPN silicon phototransistors in compact packages, designed for reliable signal coupling across isolated circuits in industrial and computing environments.
