    Who manufacures them? I know Vishay/Siliconix and Central Semiconductor.
    Someone else?

    since IRD/CRD don't normally come in large current types if guess
    they are not that popular.
    most CRD's average around a 100Ma's i think if your looking for more
    than that you would need to use a couple of high current FETS>
  3. That's an understatement. I can't remember the last ime I saw one in a
    schematic, let alone one in a circuit.
    JFETs can be connected gate to source and they become a current
    regulator. But I can't remember seeing a JFET that could dissipate more
    than a few hundred mW. At a few tens of volts, that's only a few tens
    of mA or less.

    I think they are commonly used in ICP sensor conditioning circuits (ICP
    sensors are used in vibration measurement applications)
    I'm looking for maybe 8 miliamps. And agreed, JFET can be used, however
    I'm not sure about accuracy of JFET solution at the moment.

    Any answer to my original question?

    I think Advanced Semiconductor and a company with a name like Compensated
