TVS or Transient Voltage Suppressors are special type of diodes that are designed to protect electronic equipment from electrical transients or surges. The SMBG12A-E3/1 is a type of TVS diode which is typically used in applications that require fast-acting, low-clamping, and multi-channel protection. This diode is designed to protect against over-voltage damage to circuit components by limiting the peak voltage which is connected to the circuit. The SMBG12A-E3/1 is commonly used in automotive, industrial, telecom, and consumer applications. In automotive applications, this diode can be used to protect against electrical transients induced by shocks, collisions, electromagnetic interference (EMI) or surges. In industrial applications, it protects electronic equipment from damage caused by voltage spikes, electrostatic discharge (ESD) and other phenomena. In consumer applications, it may be used to protect networks, entertainment centers, game consoles and other home electronics from high-voltage surges. This diode is ideal for applications where a low voltage drop, high peak current, and fast response time are required. It has a low capacitance, low leakage current, and is UL and RoHS compliant. It is capable of withstanding up to 100V transients, and can provide up to 25A of peak current. The SMBG12A-E3/1 is designed with a forward voltage drop of about 0.7V and a reverse leakage current of 1uA. The working principle of the SMBG12A-E3/1 is based on the avalanche phenomenon. When exposed to an over-voltage, the diode will turn on, causing the voltage to be clamped to the breakdown voltage of the diode (Vbr=12V). This is known as the avalanche breakdown effect. Once the transient voltage falls below this Vbr, the diode will turn off, and the device will recover to its original state.The SMBG12A-E3/1 provides an effective way to protect electronic components from transient voltage. It is capable of withstanding extreme conditions, and provides a low forward voltage drop for excellent efficiency. As such, this TVS diode is ideal for applications such as consumer electronics, telecom, automotive, and industrial applications.
