SMBG4742CE3/TR13: Overview and Working Principle

The SMBG4742CE3/TR13 is a single zener diode designed for a wide range of applications. The diode is available in a wide variety of package styles, with low breakdown voltage ratings from 6 to 200 volts and a low maximum power dissipation of 200 mW. It is a popular choice for voltage regulating and can be used with a variety of circuits including step-down, step-up and buck-boost.The SMBG4742CE3/TR13 is a silicon planar zener diode with a series base configuration. This configuration produces a breakdown voltage of 47 V and a forward wattage rating of 200 mW. When the diode is forward biased, a voltage increase of up to 200 mV is present across the junction. Once the breakdown voltage is reached, current will start to flow through the device and the voltage will be stabilized at the rated value.The SMBG4742CE3/TR13 is commonly used in voltage regulation circuits such as in power supplies, linear regulators and battery chargers. It can also be used in transient voltage suppressors, ESD protection and TVS protection circuits. In addition, it is suitable for use in temperature sensing and controlling, current limiting and surge protection.The device is capable of handling high voltage and power, making it ideal for a wide range of industrial, automotive and telecom applications. The device is supplied in a variety of surface mount and through-hole packages, so it can be conveniently integrated into many applications.In summary, the SMBG4742CE3/TR13 is a single zener diode designed for a wide range of applications, from low-voltage to high-voltage regulating. It is a silicon planar diode with a series base configuration and a breakdown voltage rating of 47 V and a maximum power dissipation of 200 mW. The device is available in a variety of surface mount and through-hole packages, making it ideal for a wide range of applications.
