avalanche diode

Certain devices, such as avalanche diodes, deliberately make use of the effect.

Avalanche diodes can also be used as white noise generators.

This makes the avalanche diode useful as a type of voltage reference.

An avalanche diode displays a similar stable voltage over a range of current.

The avalanche diode is deliberately designed for use in the avalanche region.

Avalanche diodes are designed to break down at a well-defined reverse voltage without being destroyed.

If placed into a resonant circuit, avalanche diodes can act as negative resistance devices.

The avalanche diode is connected to the circuit so that it is reverse-biased.

A gated broadband noise source (such as an avalanche diode) drives the device under test.

Avalanche diodes can replace the spark gap for stage voltages less than 500 volts.

These are avalanche diodes designed specifically to protect other semiconductor devices from high-voltage transients.

Another mechanism that produces a similar effect is the avalanche effect as in the avalanche diode.

In each stage, the electrons are multiplied by impact ionization in a similar way to an avalanche diode.

Some commercial microwave noise generators use avalanche diodes to create a large excess noise figure that can be turned off and on.

Voltage reference diodes rated more than about 5.5 volts are avalanche diodes.

Avalanche diodes generate radio frequency noise.

Some devices labeled as high-voltage Zener diodes are actually avalanche diodes (see above).

Diodes with the corresponding effects are known as Zener diodes and avalanche diodes.

This process is exploited in avalanche diodes, by which a small optical signal is amplified before entering an external electronic circuit.

The junction of an avalanche diode is designed to prevent current concentration at hot spots, so that the diode is undamaged by the breakdown.

A unidirectional device operates as a rectifier in the forward direction like any other avalanche diode, but is made and tested to handle very large peak currents.

Zener and avalanche diodes, regardless of breakdown voltage, are usually marketed under the umbrella term of "zener diode".

Fig. 4 shows the results of reconstructing the light intensity from 4096 binary images taken by single photon avalanche diodes (SPADs) camera.

Avalanche breakdown usually destroys regular diodes, but avalanche diodes are designed to break down this way at low voltages and can survive the reverse current.

The IMPATT diode is an avalanche diode optimized for frequency generation.
