Diodes - Zener - Single

The TZQ5245B-GS18 is a Zener diode, meaning a diode with a voltage regulator, which provides a stable current at a specific voltage drop across a diode junction. It is part of a single diode family, which means that it is a unidirectional semiconductor device – it will only allow current to pass from anode to cathode, and not from cathode to anode. This single diode family is particularly well-suited for applications that need to protect components, like an electronic device, from overvoltage conditions. The TZQ5245B-GS18 is a low-power Zener diode capable of carrying up to 275mA and is designed to act as an ideal voltage regulator Its reverse breakdown voltage is 4.7V and it has a Zener power rating of 500mW and a junction temperature range of -65°C to +175°C. It also boasts a capacitance of just 16.5pF at 1MHz and 17.5pF at 100MHz. Manufactured using silicon die and a thermoplastic resin, it has a maximum available voltage of 5.46V and can provide reliable and stable operation even in high-temperature environments.Applications for the TZQ5245B-GS18 are varied. It can be used for voltage regulation, voltage reference, peak clamping, and overvoltage protection of sensitive components. It is an excellent choice for automobile and other applications that require reliable operation in high temperature. Notable examples are airbag deployment systems, engine diagnostic systems, driver sensors for power transmission control, and other automobile accessories. The TZQ5245B-GS18 is commonly used in AC/DC power supplies, LED lighting, and voltage regulators. High surge operation and high stability are very necessary in these types of applications and make the TZQ5245B-GS18 an ideal candidate. This diode can also be used in base calibration kits and switching power supplies, especially if the power supply relies on low-noise analogue signals.When it comes to its working principle, the TZQ5245B-GS18 has a much lower breakdown voltage than normal Zener diodes. Its current-carrying capability is also much higher than that of standard Zener diodes. This diode is capable of conducting up to 275mA of current and can protect components from overvoltage conditions. While standard Zener diodes will only protect from a certain amount of voltage, the TZQ5245B-GS18 can handle an even higher amount of reverse breakdown voltage and provide more protection for the connected components. The TZQ5245B-GS18 is a versatile diode with a vast range of applications. Its low-noise performance and its ability to protect components from overvoltage conditions make it suitable for use in a wide variety of applications, from automotive systems to LED lighting and even voltage regulators. Its low capacitance rating and wide junction temperature range make it one of the best choices for reliable and stable operation in any environment.
