The SMAZ18-13 is an advanced type of single zener diode. It has an operating voltage range of 18V to 13V and a maximum power dissipation rating of 500 mW. It has a fairly standard zener diode construction, consisting of an anode and a cathode, with a zener region between them.The SMAZ18-13 operates on a reverse-biased zener voltage which allows for reliable voltage coarse regulation. This makes it perfect for applications which require a stable, low-voltage supply. It is also suitable for use in switching devices such as voltage regulators and power supplies, as it can provide a reliable, low-noise output.The SMAZ18-13 has an excellent temperature coefficient, with an operating temperature range of -55°C to +125°C. This makes it highly tolerant to temperature variations, making it suitable for harsh environments. The low leakage current rating of 5 mA ensures an output voltage which is steady and consistent.The SMAZ18-13 has a very low breakdown voltage of 8.5V, making it suitable for devices and circuits with high input voltage levels. It is also suitable for automotive applications, due to its low power consumption and fast switching speeds.The SMAZ18-13 is highly reliable, with excellent long-term reliability and low noise operation. The construction of the zener diode makes it very durable, with a maximum rated operating temperature of +200°C and an operating life of over 20,000 hours.The SMAZ18-13 has a wide range of applications. It can be used as an overcurrent protection device in automotive applications, as an ESD protection diode in data lines, or as a temperature and voltage reference in industrial systems. It can also be used for voltage regulation and as a voltage reference in switching power supplies and AC-DC converters.The SMAZ18-13 works on the basic principle of a zener diode. When the zener diode is connected in reverse bias, the voltage across its terminals is held at nearly constant until the reverse voltage reaches its breakdown voltage. When the zener voltage is applied, a low current is allowed to flow, and this current is kept constant until the applied voltage reaches the required regulated level.The SMAZ18-13 is a highly reliable, low-noise single zener diode device which is suitable for a wide range of applications. It is designed to deliver reliable, low-voltage supply and can be used to protect data lines, provide voltage and temperature references, and voltage regulation in automotive and industrial applications.
