BZT55C75-GS18

The BZT55C75-GS18 is a type of small and reliable Zener diode. It is categorised as a single diode, meaning that it is only composed of one PN junction. Such diodes are used for voltage regulation and are ideal for stabilizing the voltage in power supplies of low power electronic products and low voltage circuits.

The BZT55C75-GS18 diode offers a power dissipation of 0.5W, and a maximum continuous forward current of 250mA. It also has a reverse voltage of 18V, with an operating temperature range between -50°C and 125°C. This diode is rated to a low reverse leakage current, to prevent power loss during conduction. In addition, it is also packaged in a leaded (DPAK) package. The goal of packaging like this is to provide better thermal performance, as well as to make protecting the circuit easier.

The BZT55C75-GS18 diode is widely used in applications where the regulation of a circuit’s voltage is required. It is particularly useful in voltage regulator circuits, as it can be used to keep the voltage level of a circuit constant, and to prevent overvoltage or undervoltage. Such applications include voltage stabilizers, linear voltage regulators, switching power supplies, and DC/DC converters. This diode can also be used when constructing various circuits such as analog modulation, video modulation and stabilizing luminance & color.

The working principle of the BZT55C75-GS18 diode is simple. When the voltage of the circuit falls below the Zener voltage, the diode conduction allows the current to flow, even when the current is in reverse direction. This ensures that the voltage of the circuit remains below the Zener voltage. On the other hand, when the reverse voltage reaches the Zener voltage, the diode is said to be in the “breakdown” state. This is when the diode starts allowing current to flow in the forward direction, thus stabilizing voltage in the circuit.

Overall, the BZT55C75-GS18 diode can be used in a variety of applications where voltage stabilization is critical. It has a wide operating temperature range, low reverse leakage current and a power dissipation of 0.5W. It is also packaged in a leaded package, providing better thermal performance and protecting the circuit more effectively.
