ISD203G

Transistor, Photovoltaic Output Optoisolators Overview

The ISD203G is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode with an NPN silicon phototransistor in a space-efficient dual-in-line plastic package. The 'G' suffix indicates a 10mm lead spread option. Key electrical characteristics include a minimum collector-emitter breakdown voltage (BVCEO) of 70V and a high isolation voltage rating of 5.3kVRMS with a peak withstand of 7.5kVPK. All electrical parameters are 100% tested during manufacturing.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific package variant, as the base series includes surface mount and tape-and-reel options. Confirm that the 10mm lead spread requirement matches the target PCB footprint design. Ensure the application voltage does not exceed the 70V BVCEO limit. Check for any custom electrical selection requirements if standard testing specifications are insufficient for the intended environment.
