    VA voltage for NPN (or equivalently Lamba for MOSFET-N)

    Hello, Sorry if this topic was covered already. I need a transistor (preferentially an NPN) for an current source generator. It seems that on the datasheets such VA [Volt] doesn't appear. Is there a way to calculate it from the other parameters? I have to choose a NPN for a current source with...

    32 poles dual throw (switch or relay)

    Hello, I need to switch one input of 32 signals between two possible outputs. My object should be named 32pdt, has anyone an idea if it exists? Or can I make it by stacking smaller switches/relay? (i.e 32 times spdt switches/relays) Signals are max 48V, max 3A. Contact resistance <50 mohm...
