Zener diode is a heavily doped piece of SC. If in a diode, the extrinsic side has more doping, it will create less space for depletion region. And vice versa. In zener, the doping is so heavy on both sides, that both the sides N and P will allow lesser depletion region in them. Which is why zener has thin depletion region.
