switching diode

switching diode

[′swich·iŋ ‚dī‚ōd]
(electronics)
A crystal diode that provides essentially the same function as a switch; below a specified applied voltage it has high resistance corresponding to an open switch, while above that voltage it suddenly changes to the low resistance of a closed switch.

Also, a much cheaper diode (like the switching diode 1N4148) was found to yield a comparable performance and forms an effective substitute for the expensive Schottky diode.
Since the switching diode is off (high resistance) in between samples (typically in nanoseconds), the average capacitor voltage would not discharge but rather after many RF cycles would eventually reach the amplitude of the RF signal.
Featuring breakdown voltage ratings of 75V, 80V and 85V, this product line offers switching diode arrays in the miniature plastic SOT563, DFN1006-3 and DFN2020-6 packages.

DALLAS -- Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today introduced a miniature quad switching diode array, the MMBD5004BRM, which was designed for bridge implementation and ideally suited for Modem (Modulator-demodulator) tip/ring interface and general light duty offline rectification applications.
Each of the three Schottky-barrier diodes (HSMS-282Y, HSMS-285Y, HSMS-286Y) and the single PIN (positive-intrinsic-negative) switching diode (HSMP-389) is supplied in the low-cost industry-standard SOD-523 (small outline diode) package.
the global leader in circuit protection, introduced a series of Schottky Barrier Rectifiers designed to outperform conventional switching diodes in commercial, industrial and automotive applications.
That is due to the fact that the biasing circuitry and switching diodes are arranged in the feeding structure rather than the radiating structure (the patch).
