BZX79-B2V4,133

Single

BZX79-B2V4,133 is a single Zener diode. It is mainly used in a variety of safety-critical applications to protect an electronic product from overvoltage or to provide voltage reference. Its working principle is what is known as a Zener effect.

The Zener effect is the ability of a diode to conduct current in the opposite direction of its normal direction, if the voltage across it exceeds a certain voltage level. This is also known as breakdown voltage. BZX79-B2V4,133 breakdown voltage is 2.4V ±5%. When it exceeds the Zener voltage, current will flow in the opposite direction and cause the voltage to stabilize at the Zener voltage.

BZX79-B2V4,133 is popularly used in voltage regulation. It produces stable and constant output voltage, regardless of fluctuations in the voltage of the power supply. This characteristic is useful in providing an accurate reference in low-power op-amp circuits and regulating input voltages in power supplies.

It is also often used in protecting circuits from electrical noise, in peak voltage suppression, in switching circuits, and in voltage regulators.

BZX79-B2V4,133 is capable of handling power up to 500mW. It is made with a glass-coated chip and a Type-2 compound sealed leaded package. It is useful in many applications from battery powered circuits to high-power lighting systems.
