Diodes - Zener - Single comprise of a single diode that can sustain a predetermined reverse voltage indefinitely. The application field of the DDZ8V2B-7, a two-terminal diode, is broadly diversified, and it has a wide range of applications. Its working principle is also based on the operation of the single diode that it uses.

The breakdown voltage specs for the DDZ8V2B-7 are specified as 8V, and its maximum power dissipation is 30mW. This diode typically exhibits an ideality factor of between 1.5 to 2.5. This diode can be used for a number of applications where recognition voltage, steady voltage, and waveform clipping are needed. Power-saving systems, waveform limiters, shunt generators and AC/DC converters are among the common uses of this DDZ8V2B-7 diode.

When a diode is reverse-biased and a negative voltage – higher than the diode’s breakdown voltage – is applied, the current thru the diode increases and the voltage across it assumed a constant value at or near the breakdown voltage. This process is called Zener breakdown. This breakdown characteristic is the basis of the working principle of DDZ8V2B-7.

The working principle of DDZ8V2B-7 diode is that it can regulate voltage by passing some of the current through its P/N junction and reversing the current, as a result of the Zener breakdown, when a reverse voltage is applied. The breakdown voltage of this diode is 8V, and the flow of current thru the diode will be greatly increased if the reverse bias applied to it has a voltage value above the 8V. The operating temperature range for the DDZ8V2B-7 is from -55°C to +150°C, and it is suitable for use as a voltage regulator in a wide range of electronic applications.

The reverse voltage will be automatically regulated if the circuit is connected with a resistor in series with the DDZ8V2B-7. The voltage across the resistor will be fixed, and the remainding voltage will be dropped across the diode. By increasing the resistance of the resistor, the current through the diode can be decreased, limiting the power consumption of the diode.

The DDZ8V2B-7 diode can be used as a voltage reference in high voltage circuits. It produces a reference voltage after a predetermined threshold voltage is exceeded, and it is usually used in DC-DC inverters or AC-DC converters, together with different types of power transistors.

This diode can also be used for protection in depletion-mode MOSFETs. It is important that the MOSFET withstand the clamping voltage of the diode, and it is normally used with an appropriate base resistor in order to avoid overstressing the MOSFET.

In summary, the application field of the DDZ8V2B-7 is broadly diversified. Its working principle is based on the Zener breakdown characteristic of a single diode, and it can be applied to power-saving systems, waveform limiters, shunt generators, AC/DC converters, voltage regulators, voltage references, and MOSFET protection.
