The part has been obsoleted by Intersil. The important characteristics are low leakage current (less than 0.1 nA at 25C with 1 V reverse bias) and close matching of forward voltage drops. Also, the forward voltage drop with 1 nA or less current needs to be 200 mV or greater. Most common diodes turn on much earlier. The operating range is from 20C to 60C. > Thank you for your help.I have a spare new CA3039 if you are interested?
