A P-type power MOSFET, with source resistor to control the current, and a zener diode to set the gate voltage. The bias resistor, from gate to drain, only has to provide enough microamps to turn on the zener. The zener voltage should be 6.8 volts or higher because lower voltages do not zener well at low current.
