Diodes are electrical components that allow electrical currents to flow in one direction and block electrical currents in the opposite direction. Rectifiers are diode components that are used to convert alternating electrical currents (AC) into direct current (DC). Single phase rectifiers are used to control and stabilize the power of a single DC circuit. The BAS82-GS18 application field and working principle are based on the principles of single phase diodes and rectifiers.

The BAS82-GS18 is mostly used as a protective diode for voltage protection or as a free-wheeling diode. It is a small-signal diode package that offers high-current capabilities. The BAS82-GS18 is designed to protect against overvoltage conditions that can cause damage to the circuit. The diode is small in size and offers good heat conductivity due to its high power rating, making it ideal for applications that require quick heat transfer. The BAS82-GS18 features high surge current performance due to its low forward voltage drop.

The BAS82-GS18 operating at low forward current provides protective function and performs as a standard diode. At high forward current, its rectifying properties take over to provide overvoltage protection. The BAS82-GS18 has a maximum forward current rating of 210mA and reverse voltage rating of 75V. Its reverse voltage break-down rating is also 75V. It can sustain a peak surge current of 1A.

The BAS82-GS18 can be used as a Power Rectifier Diode for applications such as LEDs, CFLs (Compact Fluorescent Lights) or other light sources. It can also be used as an ideal diode for motor-control circuits, dc-dc converters, switching transistors, and flyback transformers. It can be used in AC/DC rectification circuits, electromagnetic interference suppression, and resonance circuits. In automotive applications, the BAS82-GS18 can be used in the production of electronic ignitions, integrated circuit protection, reverse voltage protection and steering functions.

The BAS82-GS18 diode works on the principle of carrier injection when under forward current. It uses N-type doping, where a majority number of electrons are injected into the diode and allows current to flow towards the anode in a single direction. As the voltage across the diode increases, the electron current increases and functions like a switch. This allows the BAS82-GS18 to work as a switch to rectify the current and protect it from overvoltage damages.

The BAS82-GS18 is constructed of an axial package and its single diode is mounted in a circular, rubber-retaining ring with a white body. The terminal leads for the anode and cathode are made of tin-plated brass, with a 1.0mm diameter and a 1mm length. The device offers a maximum power dissipation of 500mW and an operating temperature of -55°C to + 125°C.

The BAS82-GS18 is a single-phase, general-purpose diode rectifier and is ideal for controlling and stabilizing the power in DC circuits. It offers high surge current capability with a low forward voltage drop and can be used as a protective and free-wheeling diode. It is also suitable for light sources, motor-control circuits, dc-dc converters, and flyback transformers. The BAS82-GS18 can be used to protect against damage from overvoltage conditions.
