Zener diodes are a special kind of diode which permits current to flow in the forward direction. What makes them different from other diodes is that Zener diodes will also allow current to flow in the reverse direction when the voltage is above a certain value. This breakdown voltage is known as the Zener voltage.

Ultrafast rectifiers can directly reduce switching loss and improve overall power efficiency due to a good combination between reverse recovery time and forward voltage. Some features and benefits include high reverse voltage surge capability, high thermal cycling performance, low thermal resistance, and very low on-state loss.

Switching diodes are a single p-n diode in a discrete package. A switching diode provides the same functionality as a switch. It has high resistance below the specified applied voltage like an open switch, whereas above that voltage it changes in a sudden way to the low resistance of a closed switch. Switching diodes are used in devices such as ring modulation.

The PN junction of a small signal diode is usually encapsulated in glass to protect it and generally has a black or red band at one end of its body identifying it as the cathode end of the terminal. Small signal diodes have lower current and power ratings in comparison to rectifier diodes but can function better in high frequency applications or in switching and clipping applications which deal with short-duration pulse waveforms.

 A Schottky diode, also known as a hot carrier diode, is a semiconductor diode which has a low forward voltage drop and an extremely fast switching action. There is a small voltage drop across the diode terminals when current flows through a diode.

As opposed to an integrated circuit, discrete semiconductors perform a single electronic function. Discretes are categorized into diodes, transistors, and several other types, and are used in a variety of applications such as voltage regulation, surge protection, switching, power conversion and more. We offer a full line of discrete semiconductors from distinguished brands.
