Introduction

BZX384B3V0-E3-08 is a single zener diode from Diodes Incorporated, which is specifically designed to be a voltage reference in several devices. It is available in the SOD-120 package and provides excellent properties such as low dynamic impedance, repeated reverse energy capability, high temperature stability and good temperature coefficient. It has a reverse voltage break down capability of 3.3V.

Application Field

BZX384B3V0-E3-08 is mostly used in a diverse array of analytical and test instruments, automotive and consumer electronics, computer and peripherals, communications and industrial applications. This diode is typically used as clamping and transient dampening components, where it provides low dynamic impedance, and helps protect against over voltage transients. In consumer electronic applications, single zener diodes like this one can be used to protect circuits from momentary noise spikes, power surges and other transient voltages. The diode can be used to establish a stable voltage reference, from which other electronic components can draw reference voltage.In automotive applications, this zener diode can be used for power management and voltage regulation. When used as a voltage regulator, the diode can be used in conjunction with capacitors and other components to provide voltage regulation over an extended range of input voltages. This helps to keep the energy supplied to the circuits in the car stable, even when the vehicle is operating in extreme temperatures and conditions.

Working Principle

A BZX384B3V0-E3-08 Zener diode works on the principle of reverse breakdown. When a certain reverse-biased voltage is applied to the diode, a large amount of current passes through it and clamps the output voltage near its breakdown voltage. This voltage is almost constant, even if the reverse bias voltage changes slightly.The breakdown voltage of the diode can be adjusted by using a series resistor. The diode’s breakdown voltage is proportional to the reverse voltage, which is applied to it, divided by the resistance of the series resistor.In addition, it is also possible to adjust the zener diode’s bandwidth and its voltage regulation. To do this, a shunt resistor is introduced between the diode and ground. The current flowing through the diode and the shunt resistor can be used to adjust the bandwidth and the voltage regulation.

Conclusion

The BZX384B3V0-E3-08 is a single zener diode from Diodes Incorporated, which is specifically designed to be a voltage reference in several devices. This diode is typically used in a variety of consumer, automotive and test instruments devices, as a clamping and transient dampening components and it helps to protect circuits from transient noise spikes, power surges and other transient voltages. The diode works on the principle of reverse breakdown and it is possible to adjust its breakdown voltage and voltage regulation characteristics by means of series and shunt resistors.
