2. Zener diode - Wikipedia

   en.wikipedia.org/wiki/Zener_diode

   For example, a diode with a Zener breakdown voltage of 3.2 V exhibits a voltage drop of very nearly 3.2 V across a wide range of reverse currents. The Zener diode is therefore well suited for applications such as the generation of a reference voltage (e.g. for an amplifier stage), or as a voltage stabilizer for low-current applications. [2]

3. Clipper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Clipper_(electronics)

   A simple diode clipper can be made with a diode and a resistor. This will remove either the positive, or the negative half of the waveform depending on the direction the diode is connected. The simple circuit clips at zero voltage (or to be more precise, at the small forward voltage of the forward biased diode) but the clipping voltage can be ...

4. TL431 - Wikipedia

   en.wikipedia.org/wiki/TL431

   Reference voltage vs free-air temperature at test conditions. Design-center (middle plot) and worst-case deviation of ±2% (upper and lower plots) [12] The nominal reference voltage, V REF =2.495 V, stated in a datasheet, is tested in zener mode at an ambient temperature of +25 °C (77 °F), and I CA =10 mA. [13]

5. Joule thief - Wikipedia

   en.wikipedia.org/wiki/Joule_thief

   A simple modification of the previous schematic replaces the LED with three components to create a simple zener diode based voltage regulator. Diode D1 acts as a half-wave rectifier to allow capacitor C to charge up only when a higher voltage is available from the joule thief on the left side of diode D1. The Zener diode D2 limits the output ...

6. Reference designator - Wikipedia

   en.wikipedia.org/wiki/Reference_designator

   Separable assembly or sub-assembly (e.g. printed circuit assembly) AT: Attenuator or isolator: BR: Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode ...

7. Clamper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Clamper_(electronics)

   Clipper (electronics), a circuit that imposes a fixed limit and does not offset the signal; Envelope detector, a circuit that outputs the maximum (or minimum); a clamper with the diode and capacitor exchanged; Schottky diode; Snubber, a circuit that reduces dV/dt or limits peak voltage, in order to reduce arcing or breakdown
