The GDZ27B-HG3-18 is a single Zener diode belonging to the family of Zener diodes. It is a signwave clamping device that prevents high voltage spikes fromOccuring in electrical systems.

The main feature of the GDZ27B-HG3-18 is its versatility, as it can be used in a variety of applications including power supply and voltage regulation circuits, as well as for protection of analog signals. It is available as a 350mWatt package, which makes it ideal for use in high power circuits. Additionally, it is rated for a peak repetitive reverse voltage of 700 volts, which makes it suitable for use in circuits with higher voltages.

The GDZ27B-HG3-18 operates by allowing current to flow in only one direction. When a current is applied in the proper direction, the voltage is clamped to a specific level, regardless of the input voltage, which makes it ideal for both linear and switched mode power supplies, as well as for protection of analog signals.

In linear power supplies, the device clamps the output voltage to a specific level, which is chosen based on the application. For example, for analog signal protection, the device might be set to clamp voltages above 6 volts. In switched mode power supplies, the device is set to provide an overvoltage protection by clamping voltage spikes above a certain level.

In addition, the GDZ27B-HG3-18 is also capable of providing a surge current carrying capacity, which can provide short-term protection in the case of overvoltage, as well as during load transients. This feature makes the device suitable for applications such as motor driver circuits, as they often require a sudden input current.

The GDZ27B-HG3-18 has a wide operating temperature range, making it suitable for use in both indoor and outdoor applications. Additionally, it is highly reliable, with a maximum heat dissipation of 2.4 watts and an operating temperature range of -65 to 150 C.

Overall, the GDZ27B-HG3-18 is a versatile device, which can be used for a variety of applications, including power supply and voltage regulation circuits, as well as for protection of analog signals. Additionally, it also provides a surge current carrying capacity and reliable operating temperature range, making it ideal for applications involving high power and/or temperature dependent operation.
