The GDZ36B-HE3-18 is a singlediode that belongs to the Zener family of electronic components. Its general purpose is to protect electric circuits or sensitive electronic equipment from damage caused by power outages or surges. It is widely used in a variety of applications, such as:

• Computer and peripheral devices
• Medical devices
• Telecommunication systems
• Aerospace components
• Automotive safety control systems
• Energy management systems

The GDZ36B-HE3-18 features a reverse blocking voltage of 18 volts anda continuous power dissipation of 625 mW at 25° C. This diode is produced in a conventional, hermetically sealed, planar case for better strength and heat dissipation. It has a 3-lead configuration, namely, an anode and cathode lead, and a third lead connected to the anode.

The working principle of the GDZ36B-HE3-18 is as follows: When reverse bias voltage is applied, a small current flows through the diode, which keeps the voltage across the device at a constant level regardless of the applied voltage. This process is known as the Zener Breakdown Effect. As the reverse bias voltage increases, the Zener diode gets more and more conductive.

Under the reverse bias voltage, the diode has two operations. During the avalanche voltage breakdown condition, the diode is said to be highly conductive and will dissipate large amounts of power. This state is called the Zener Breakdown Effect. Under this condition, the diode behaves like a short circuit and draws large currents from the power supply until the circuit is damaged.

The second operation is the Zener mode. In this mode, the diode conducts just enough current to keep the voltage stable at a certain level known as the Zener voltage. This mode helps protect the circuit from damage due to excessive current or reverse bias voltage.

The GDZ36B-HE3-18 is ideal for use in applications where reverse bias protection and noise protection are needed. It can also be used to stabilize power supplies, maintain safe operating temperatures, and protect sensitive electronic equipment and circuits. Its hermetically sealed case helps dissipate the heat generated during operation, which effectively increases its shelf-life.
