This type of diode is particularly useful in electrical circuits because it can provide excellent protection from voltage spikes and other forms of electrical noise.
Working Principle
The BZX84J-B43,115 operates on the principle of Zener diode action. When the forward voltage across the diode exceeds the rated breakdown voltage, the diode begins to conduct in the reverse direction. This results in electrical current flowing from the P/N (positive-negative) terminal to the T1 terminal, or vice versa. The diode limits the voltage across the diode to the breakdown voltage, which prevents the diode from being damaged. Additionally, the low voltage drop across the diode allows for a consistently reliable current output.
Rating and Characteristics
The BZX84J-B43,115 has a maximum power dissipation rating of 150 mW, while its maximum voltage rating is 43.115 +1 to -1. The breakdown voltage of the diode is 0.7V. It has a maximum reverse current rating of 4 nA, while its maximum forward current rating is 30 mA. The diode has a junction temperature range of -65F to + 175F and is lead-free.
Conclusion
The BZX84J-B43,115 is a single type Zener diode component and is highly reliable for a wide range of applications. It offers low voltage drop, low tolerance and a small size, making it suitable for a variety of uses such as circuit protection, device control and DC power control. With a power dissipation rating of 150 mW, a reverse current rating of 4 nA, and a forward current rating of 30 mA, this diode is a reliable, efficient and effective choice for many types of electrical circuits and devices.
