BZD27C22P R3G Discrete Semiconductor Products

The BZD27C22P R3G is a form of single Zener diode, a device used to control voltage within a circuit. The Zener diode is constructed with a slightly reversed PN junction, allowing for the flow of current in a reverse-biased active region. This reverse-biased active region can be used to control the maximum voltage of a circuit. The actual voltage value is determined by the construction and materials used within the diode.

This particular diode has a maximum reverse voltage of 27 volts, a power dissipation of 400 mW and the following electrical characteristics: Zener voltage of 21.5 V ± 1.8 V, Current - Reverse (Leakage) I_R = 5.0 μA at 25°C, Dynamic Resistance R_z = 10.9 Ω @IZT and Operating/Storage Temperature Ranges: -65°C to +200°C.

The BZD27C22P R3G provides two main purposes within a circuit, controlling the maximum voltage and acting as a signal clip. By introducing a part with a fixed voltage value of 21.5 volts, the voltage on the rest of the circuit will never exceed this point, thus providing over-voltage protection. The other purpose is signal clipping, inverting certain bipolar signals, such as in a sine wave signal. When the signal passes over the Zener voltage, it can clip one part of the signal and invert the other part, as desired.

Working with the BZD27C22P R3G is relatively straightforward. The part should be placed in series between the power source and the load, and it is recommended to use at least one 10μF capacitor across the diode to reduce any voltage spikes. To increase the part\'s accuracy, the assembly should include a resistor in series with the diode to protect against excess current.

Due to its wide operation and storage temperature range, the BZD27C22P R3G can be used in various applications, such as cellular phones, MP3 players, DVD players, set-top boxes and other portable electronic devices. It can also be used in automotive applications, computers, test and measurement equipment, as well as radio frequency (RF) circuits.

In conclusion, the BZD27C22P R3G is a single Zener diode used in various applications such as portable electronic devices, automotive systems, computers and test and measurement equipment. It works by introducing a part with a fixed voltage value of 21.5 volts, providing over-voltage protection and signal clipping. The part should be placed in series between the power source and the load, and connected with a 10μF capacitor across the diode to reduce any voltage spikes.
