Abstract
A zener diode is disclosed which is temperature-compensated for a special application. If a zener diode is operated with a switch shunted across it, and its on-off ratio is variable, its dissipation will vary. It is proposed to form on the zener diode crystal an additional dissipative component which is switched on/off in an opposite sense to that of the zener diode. Thus, the total dissipation remains constant.
