Trevor, the BU208D does indeed have a reverse diode and resistor: http://www.alphacron.de/download/hardware/BU208D.pdf
It strikes me that this is an ideal sort of device to use in an ignition system too. In the absence of a diode the CB junction is pretty tough and if the base is driven from a low Z source it will give some energy recovery without blowing up. Exactly how much is another question.
