BZT52B2V4-G3-18

Diodes - Zener - Single

The BZT52B2V4-G3-18 Zener diode is a one-way current valve, used in a broad range of applications. It operates by allowing current to flow in one direction, while restricting current flow in the opposite direction. This makes them ideal for regulating electric power, ensuring that excessive voltages don\'t destroy sensitive electronic devices.

This particular type of diode, the BZT52B2V4-G3-18, is a single zener diode. It can handle maximum reverse power dissipation of 0.125 W and peak forward power dissipation of 0.75 W. The maximum operating junction temperature is +140°C, and the typical reverse current leakage is 0.010 μA.

The device\'s most common application is as a voltage regulator. Its zener characteristic curve allows it to have a very stable, controlled voltage drop from the input to the output. This prevents circuitry from being damaged by a high excess voltage due to power fluctuations.

The diode\'s operating principles are surprisingly simple. When the voltage across the diode is positive, indicating a current flow from the anode to the cathode, the diode behaves like a normal conductive device. Electrical current flows freely with minimal resistance. When the voltage is reversed, however, so that current is trying to pass from the cathode to the anode, the diode behaves like a resistor. This restricts current flow in the opposite direction and prevents the circuit from being damaged by an excess of voltage.

The BZT52B2V4-G3-18 Zener diode is a small but important component, capable of protecting delicate circuits from damage. Its ability to regulate voltage is both highly reliable and incredibly efficient, and its reverse-biased characteristic makes it an ideal choice for voltage regulation applications.
