Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

Diodes has introduced a pair of 80V ideal diode controllers to protect against reverse connections and voltage transients. Minimum operating voltage is 3.2V. “The controllers have all the features ...

An alternative method for switching a load between battery and external charger uses less power than the usual diode-OR circuit. It requires a charger with Power OK (POK) feature. Most rechargeable ...

This Design Idea illustrates a way to make use of MOSFETs’ parasitic body diodes in a power circuit that can be used in UPS and energy-recovery (e.g., regenerative braking) designs. The circuit can ...
