Operation at low currents

The Zener diode noise phenomenon requires characterizing the performance of Zener diodes at low currents in order to provide stable voltage regulation. For low-operating-current applications, our 8.2V Zener diodes exhibit low Zener voltage drift in the 50µA-to-500µA test current range.

Benefits:

• Small multisource package options save printed circuit board space as well as bill-of-materials costs compared to regulator integrated circuits.
