PIN diodes will be tailored for a particular use.

PIN diode solid state electronic devices for detecting incident light.

A PIN diode operates under what is known as high-level injection.

The PIN diode has a poor reverse recovery time.

PIN diodes are sometimes used as input protection devices for high frequency test probes.

PIN diodes are also used in power electronics, as their central layer can withstand high voltages.

Under zero or reverse bias, a PIN diode has a low capacitance.

If the input signal is within range, the PIN diode has little impact as a small capacitance.

As a photodetector, the PIN diode is reverse biased.

PIN diodes can be used in limiter circuits to reflect the energy back to the source or clip the signal.

A PIN diode, suitably biased, therefore acts as a variable resistor.

In a PIN diode, the depletion region exists almost completely within the intrinsic region.

The photons are incident on the n-doped layer unlike a PIN diode.

On a laminar semiconductor, a so-called PIN diode is exposed to a tiny spot of light.

The appropriate high pass filter output is selected with a PIN diode with logic levels.

The fastest opto-isolators use PIN diodes in photoconductive mode.

The capacitance of an off discrete PIN diode might be 1 pF.

For example, some low phase noise oscillators use PIN diodes to range-switch inductors.

At high frequencies, the PIN diode appears as a resistor whose resistance is an inverse function of its forward current.

A PIN diode obeys the standard diode equation for low frequency signals.

PIN diodes are useful as RF switches, attenuators, and photodetectors.

Consequently, the PIN diode makes a good RF switch.

By changing the bias current through a PIN diode, it's possible to quickly change the RF resistance.

PIN diodes might be used, for example, as the bridge and shunt resistors in a bridged-T attenuator.

The PIN diode bias is provided by the PA unit and flows through the primary transistor.
