The breakdown region of a transistor is the region where the supply voltage, Vcc, becomes so large that the collector-emitter junction of the transistor breaks down and conducts, even though there is no base current.

What is breakdown voltage of diode?
The critical value of the voltage, at which the breakdown of a P-N junction diode occurs is called the breakdown voltage.The breakdown voltage depends on the width of the depletion region, which, in turn, depends on the doping level. The junction offers almost zero resistance at the breakdown point.
How does the zener diode protect the meter?
The zener diode protects the meter by stabilizing the voltage when it goes in to the breakdown region.
In what region of their characteristic curve are zener diodes operated?
Zener diodes are normally operated in their reverse breakdown voltage curve.
Difference between avalanche and zener breakdown?
A: There is no difference except for a zener its breakdown is known and predictable. Avalanche breakdown is not predictable and usually happens at hi voltage and because of it if the current is not limited it self destroy the device
How can avalanche breakdown be avoided in FET?
Breakdown depends on the electric field value in FETS (as in diodes and such, where you can find a junction). Theoretically, you need to - dope less the junction region of your device (like p-i-n diodes, the i (intrinsic) region is not doped in order to reduce E field peak, which occurs near the center of the device). - raise the length of your device Both of these two solutions will have the drawback of increasing your ON resistance. At circuit design level, you can protect your devices with clamp diodes or something similar.
What are the types of breakdown region in diode?
zener breakdown and avalanche breakdown.
Why does voltage remain constant in the reverse breakdown region in a zener diode?
This space is for answering "http://wiki.answers.com/Q/Why_does_voltage_remain_constant_in_the_reverse_breakdown_region_in_a_zener_diode" Why does voltage remain constant in the reverse breakdown region in a zener diode?

The junction offers almost zero resistance at the breakdown point.
What is the function of zener dioed?
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
What is medical terminology breakdown of the word suprapubic?
As the name suggests it means above the pubic region
What is the breakdown of the medical term abdominocentesis?
This is a procedure where the abdominal region is punctured with a needle to collect fluid for testing.
How does the zener diode protect the meter?
The zener diode protects the meter by stabilizing the voltage when it goes in to the breakdown region.
In what region of their characteristic curve are zener diodes operated?
Zener diodes are normally operated in their reverse breakdown voltage curve.
What is the difference between Junction diode and Zener diode?
The difference is , the break down in a zener is desirable, well designed, expected, healthy and designed for a particular value. After breakdown, it can and is expected to maintain that condition for a long time. zener is optimized to work in this region.They are designed to have very low breakdown voltages. In contrast, the break down in a rectifier diode is undesirable, not well designed, not respected. This diode is optimized to work in the rectifier region and optimized for that. Breakdown region is avoided in normal operation. The breakdown voltage is normally very high, above 100 volts.
How do you xxplain the zener shunt regulator?
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
