... The series also offers the choice of drain voltage to be set for the FETs, the ZNBG3000 gives 2.2 volts drain whilst the ZNBG3001 gives 2 volts. These devices are unconditionally stable over the full working temperature with the FETs in place, subject to the inclusion of the recommended gate and drain capacitors ...

... ZNBG3000 ZNBG3001 TYPICAL APPLICATION CIRCUIT APPLICATIONS INFORMATION The above is a partial application circuit for the ZNBG series showing all external components required for appropriate biasing. The bias circuits are unconditionally stable over the full temperature range with the associated FETs and gate and drain capacitors in circuit. ...

... Should the negative bias generator be shorted or overloaded so that the drain current of the external FETs can no longer be controlled, the drain supply to FETs is shut down to avoid damage to the FETs by excessive drain current.
