I thought i had this transistor ordeal sorted...

Now then? The data sheet ..


Emitter base 4v
Collector base 50v
Collector emitter 50v

How can you use 12v regulated as  pass transistor (via the zener)  but the base has a max of 6v...

Huh?

The value of 4V shown for VEBO is the maximum voltage that can be applied between the emitter and base in the reverse direction.

When used in the circuit shown, the base - emitter junction is forward biased, and there will be a voltage of around 0.7V across it.

VBE vs. VEB

What's in a name?  A lot.

Are you saying up to 50v can be applied to the base?..  smiley-cool

Give them an inch and they'll take a mile.
There's that VCBO spec, too
