1.5SMC47 Application Field and Working Principle

1.5SMC47 is a type of transient voltage suppressor (TVS) diodes. The main purpose of these devices is to protect external components from overvoltage and other transients due to lightning, test and ESD. It can be used in a wide range of applications such as automotive, telecommunications, consumer electronics etc. The 1.5SMC47 consists of an two diodes connected back to back in an axial-leaded package. The anode of one diode is connected to the cathode of the other, and the anode and cathode leads of the assembly are outputted through the package for connection to the external circuit. The device has a peak pulse power dissipation of 500 Watts and a clamping voltage of 17V at 1 ampere (Ipp). In general, a transient voltage suppressor diodes works by clamping or limiting the voltage transient level below a predetermined threshold to protect vulnerable electronic components. In the case of the 1.5SMC47, it is capable of suppressing voltage transients up to 17v. When a voltage transient reach the diodes breakdown voltage level, the diodes will be switch on and quickly shunt away the excess current. This helps protect individual components from overvoltage. The 1.5 SMC 47 can be used in a wide range of applications including automotive, consumer electronics, telecommunications, and industrial control systems. For example, it can be used in automobiles to protect ECU systems, ABS systems, SRS systems, and other components from voltage transient damage when a vehicle is hit by lightning or is subjected to an electrostatic discharge. It can also be used in consumer electronics devices such as smart phones, tablets, and laptops to protect internal components from voltage transients. In addition, the 1.5SMC47 can be used in telecommunications systems such as cable and satellite systems, VoIP systems, cellular networks, and the like. In these applications, the device helps protect network infrastructure components from overvoltage and electrostatic discharges. In industrial systems, the device can help protect motor controllers, temperature and pressure sensors, and other critical components from voltage transients. Overall, the 1.5SMC47 is a type of transient suppressor diode that can be used to protect a wide range of electronic components from overvoltage and other transients. It has a peak pulse power dissipation rating of 500 Watts and a clamping voltage of 17V at 1 ampere. This makes it an ideal choice for use in automotive, consumer electronics, telecommunications, and industrial applications.
