TVS - DiodesTransient Voltage Suppression (TVS) diodes are semiconductor components that protect sensitive electronic equipment from harmful electrical surges. The SMBG43AHE3/5B Transient Voltage Suppression Diode is a high-performance, low capacitance diode designed to protect communications, datacom, and Ethernet systems from transient voltage surges. The SMBG43AHE3/5B diode is RoHS compliant and can satisfy a wide range of applications.This diode is a product line of unidirectional TVS diodes from Vishay\'s SMBG series designed for transient voltage surge and ESD protection. The SMBG43AHE3/5B diode is a twin-diodes package that comes in a very small, low CAP DFN5005-2 package. It has an adjustable breakdown voltage range 5.2V to 5.7V with a 3V dynamic and 5V static operating voltage. It has an ultra-fast response time of 1.0ns typical and provides superior ESD protection with an HBM rating of 25A and a peak pulse current of 83A.The SMBG43AHE3/5B TVS diode protects sensitive electronic equipment from surge voltages, also known as transient over-voltages, caused by sources such as lightning strikes, switching transient, inductive voltage spikes, etc. The SMBG43AHE3/5B is ideal for protecting high-speed data ports, such as HDMI, Ethernet, USB, PCIe, and SATA, from voltage surges that could cause data corruption and system failure. It can also be used in LED lighting applications.The working principle of the SMBG43AHE3/5B diode is very simple. When the voltage surge is higher than the breakdown voltage, the diode will start to conduct the surge current quickly and safely clamps the voltage to the rated breakdown voltage. The SMBG43AHE3/5B also has non-linear, low capacitance characteristics which prevent any overshoots that could cause damage to the electronic components.The SMBG43AHE3/5B TVS diode can dissipate energy up to 400W and has an operating temperature range from -40℃ to +125℃. It has a 1000V RMS isolation voltage, which ensures only the surge energy is passed from the input to the output, and that electromagnetic interference (EMI) is kept to a minimum.In summary, the SMBG43AHE3/5B diode is a versatile and reliable TVS diode designed for transient voltage surge and ESD protection in a wide range of applications. It has a fast response time, a wide operating temperature range, an adjustable breakdown voltage, and superior ESD protection. The SMBG43AHE3/5B diode is RoHS compliant and is an ideal choice for protecting high-speed data ports and LED lights.
