ZTK6.8 thru ZTK33

Vishay Semiconductors

formerly General Semiconductor

Voltage Stabilizers

DO-204AH (DO-35 Glass)

Features

• Temperature-Compensated Stabilizing Circuits

• Monolithic linear integrated circuits with

extremely short thermal run-in time producing a con-

stant temperature-compensated voltage. They are par-

ticularly suitable for stabilizing the tuning

voltage in radio and TV tuners employing voltage-

variable capacitance diodes.
