Diodes - Zener - Single

BZT55C47 L1G is a Zener diode, used to protect high current IC components from system overload. This kind of diode is used to limit the voltage beyond which system components can be damaged from high current flow. The BZT55C47 L1G Zener diode is particularly useful for protecting high current lines from current spikes, by offering low voltage resistance at reverse bias, allowing for the high-current flow.

Application Field

BZT55C47 L1G Zener diodes can be used for a variety of applications. This type of diode is widely used for noise protection in automotive and industrial electronics, telecommunications, and power supplies. It is also used for over-voltage/over-current protection, current limiting, and inlet surge protection in various switching power supplies. Additionally, this type of diode is also suitable for transient voltage suppression in 100-690V AC applications.

Working Principle

Zener diodes, such as the BZT55C47 L1G, work based on the same principle as any other diode. When forward biased, current passes through the diode relatively easily. However, when reverse biased, the diode has a tendency to resist current flow, based on its breakdown voltage, which is set by the manufacturer. The BZT55C47 L1G Zener diode has a breakdown voltage of 39V, which means that current cannot flow through the device above that voltage.

This is useful in situations where high current and voltage spikes may occur. The Zener diode absorbs the voltage, preventing it from damaging components upstream. The Zener diode also acts as a surge protector, which can be used to protect circuits and components from power surges or sudden power spikes.

When the voltage rises above the breakdown voltage, the current starts to increase, which is limited by the resistance of the diode itself. This keeps the current to a safe and predefined level, and prevents high voltage from damaging the components. The BZT55C47 L1G Zener diode also has a low forward voltage drop, which makes it more efficient in absorbing current without dissipating too much power.

Due to their unique characteristics and ability to limit voltage and current, Zener diodes are a vital component of most power supplies, circuits, and systems. The BZT55C47 L1G Zener diode can withstand large amounts of current and voltage, thereby helping to protect your system and components from damage.
