It has a peak surge current of 2 amperes (mA), and a capacitance of 2.3 pF. Finally, its average junction capacitance is 17 pF.

Application Field

The BZV55C43 L1G is primarily used for power conditioning applications, such as power supply regulation, clamping, and transient-suppression. It is particularly useful in high voltage applications,clamping, and protecting consumer electronics. Due to its wide operating temperature range, the BZV55C43 L1G is also suitable for use in automotive, industrial, and military applications.

Working Principle

The BZV55C43 L1G is a zener diode, which is designed to operate in a reverse-biased state. This means that in normal operation, the diode is reverse-biased, with the voltage across it being higher than the Zener breakdown voltage. When the voltage across the diode rises above the breakdown voltage, a large current flows through, causing it to conduct. This current is limited by the amount of current that can pass through the diode, which is determined by the Zener breakdown voltage.

When the diode conducts, it acts as a voltage regulator, as it prevents the voltage across it from rising any further. It also acts as a clamp for any excess voltage, as it will divert extra voltage to the diode, preventing it from damaging other components. Finally, the diode can be used as a transient-suppression device, as it will divert any sudden changes in voltage away from important circuits.

Conclusion

The BZV55C43 L1G is a single zener diode with a 3-pin configuration, and is capable of handling loads up to a maximum breakdown voltage of 43 volts. It is primarily used for power conditioning applications, such as power supply regulation, clamping, and transient-suppression. It is particularly useful in high voltage applications, clamping, and protecting consumer electronics, thanks to its wide operating temperature range. It works by functioning in a reverse-biased state, and is capable of serving as a voltage regulator, clamp, and transient-suppression device.
