TZM5243B-GS18

TZM5243B-GS18 is a single Zener diode, which belongs to the TZM range of mini MELF packages. It consists of a single diode, connected in series on a Lead Frame with a total of 18 Pins providing very high reliability. The TZM5243B-GS18 is designed to provide the maximum in surge current capability and the maximum voltage regulation. The TZM5243B-GS18 is manufactured to offer the highest levels of power dissipation and thermal resistances, allowing them to withstand excessive diode temperature rise.The TZM5243B-GS18 is a low voltage breakdown diode that is designed to maintain a given voltage, usually 5.3V, across a connection. It consists of a single p-n junction, with a direct current flowing through it, creating a voltage drop across the junction. It is designed to have a reverse breakdown voltage rating of 5.3V, meaning that it will shut off when it reaches that voltage, thus preventing a higher voltage from being applied to the load.The TZM5243B-GS18 can be used in a wide range of applications including power supplies, audio amplifiers, computer and telecom systems, automotive systems, power regulators and converters, sensors, meters and other high voltage applications. Its features also allow it to be used in applications that need to maintain voltage regulation, such as lighting systems and industrial equipment.The TZM5243B-GS18 works by allowing a reverse current to flow when the forward voltage reaches the Breakdown Voltage, or Zener Voltage. The Zener Voltage is the point at which the junction of the diode has a large number of electron-hole pairs that are generated due to the impact ionization of electrons and holes. This effect, along with its low temperature coefficient, allows the diode to maintain a stable voltage across its connection.The TZM5243B-GS18 has a low forward voltage drop of 1.0V at 70°C, a low reverse current of 100 nA at 5.3V and a high Power dissipation of 500 mW. It also has a High temperature limit at 150°C and a High isolation voltage at 500V RMS.The TZM5243B-GS18 is widely used in various applications requiring high reliability and operating temperatures from -40°C to +125°C. It is also used in automotive batteries and other applications where high performance and operational stability are essential.In conclusion, TZM5243B-GS18 is a popular single Zener diode, widely used in a variety of applications, that offers the highest levels of power dissipation and thermal resistance, allowing it withstand excessive diode temperature rise. It features a low forward voltage drop, low reverse current and a high isolation voltage, helping it maintain a stable voltage across its connections, while its low temperature coefficient helps it maintain the Zener Voltage, keeping the load safe from excessive currents and voltages.
