When used in the reverse direction, tunnel diodes are called back diodes or backward diodes and can act as fast rectifiers with zero offset voltage and extreme linearity for power signals they have an accurate square law characteristic in the reverse direction.

Tunnel diodes are not widely used due to their low output power; their RF output is limited to several hundred milliwatts due to their small voltage swing.

DIODO TUNEL PDF
A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called diodk. Send link to edit together this prezi using Prezi Meeting learn more: Potentiometer digital Variable capacitor Varicap. Practical tunnel diodes operate at a few milliamperes and a few tenths of a volt, making them low-power devices. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch.

Diodo tunel by nicolas david ruiz penagos on Prezi
Retrieved 4 January Their negative differential resistance in part of their operating tuenl allows them to function as oscillators and amplifiersand in switching circuits using hysteresis. Archived from the original on Tunnel diodes are also more resistant to ionizing tuel than other diodes.
As voltage increases, the diode begins to operate as a normal diode, where electrons travel by conduction across the p—n junction, and no longer by tunneling through the p—n junction barrier.
As noticed on some samples of Esaki diodes, the gold plated iron pins can in fact corrode and short out to the case.
