A Zener diode is a specialized type of diode that has a low breakdown voltage. The BZG04-62-HM3-18 is a single Zener diode that features a low voltage drop-out characteristic, low reverse current and a reverse recovery time of less than 1 µsec. It is suitable for a wide range of applications including power supplies and voltage regulation.

The BZG04-62-HM3-18 has a reverse breakdown voltage of 18V, an operating temperature range of -55°C to +150°C and a power dissipation of 150 mW. It is a popular choice for systems requiring voltage stabilization. The device is small in size and can be easily integrated into circuit designs. Its fast reverse recovery time makes it capable of handling high frequency switching.

The BZG04-62-HM3-18’s working principle is based on the Zener Breakdown Effect, which states that when the applied reverse voltage to a diode reaches a certain level, the diode’s current increases sharply. This process is known as Zener breakdown. When the Zener diode is connected in reverse bias, it acts like a voltage regulator and keeps the output voltage constant. When the input voltage rises above the breakdown voltage, the diode starts to conduct, allowing a certain amount of current to flow, thus regulating the output voltage.

The BZG04-62-HM3-18 is primarily used in power supply and voltage regulation applications where a low voltage drop-out is needed. This diode can also be used in series with a regular rectifier diode in order to provide additional protection against over-voltage surges and to increase the reverse voltage capability. It is also commonly used in power converters, voltage regulators, and on-board voltage regulation circuits.

In addition, the BZG04-62-HM3-18 can also be used for over-voltage protection, by limiting the maximum voltage across a connected load. This is accomplished by tying the anode of the Zener diode to a higher voltage than the cathode of the diode, thus allowing the current to be limited to a preset value. This allows the load to be protected from transient over-voltage surges.

The BZG04-62-HM3-18 is an efficient, reliable, and cost-effective solution for voltage regulation and protection applications. Its low voltage drop-out, low reverse current, and fast reverse recovery time make it an ideal solution for a range of power supply and voltage regulation applications.
