SZP6SMB39AT3G

TVS (Transient Voltage Suppressor) diodes are widely used in electronic circuits, mainly for their ability to quickly absorb and dissipate high energy pulses. They are designed to protect electronic circuits from the damage that can be caused by transient voltage spikes and electrostatic discharge. The SZP6SMB39AT3G is a silicon-based transient voltage suppressor diode which combines the functionality of an axial lead diode and a transient voltage suppressor. It is designed for use in applications such as EMI/RFI filtering, overvoltage protection in electronic circuits, and in automotive applications.

The SZP6SMB39AT3G is a low capacitance, fast responding, thermally enhanced TVS diode. It is lead-free and RoHS compliant, composed of a monolithically integrated structure containing a pair of Zener diodes, monolithic transient voltage suppressor, and a back-to-back diode array. The diode has a low total capacitance, typically 1.3pF at 1MHz and 5pF at 100MHz. This low capacitance ensures a fast response time, typically 8ns. The SZP6SMB39AT3G is designed to be used for ESD, EFT, and surge protection, where it will dissipate energy up to 400W peak power.

The working principle of the SZP6SMB39AT3G is based on the operation of a Zener diode and a transient voltage suppressor. The Zener diode is operated in reverse breakdown, allowing it to suppress high or transient voltage. The monolithic transient voltage suppressor is connected in series with the Zener diode and further limits the voltage. It then switches rapidly into conduction whenever an transient voltage overvoltage is present. The back to back Diode array and Zener diode combination allows what is referred to as "clamping voltage" which helps protect sensititve electronic circuitry from voltage transients.

Overall, the SZP6SMB39AT3G is a versatile and reliable TVS diode, suitable for a wide range of applications. It is well suited for EMI/RFI filtering, overvoltage protection in electronic circuits, and in automotive applications. It is a low capacitance, fast responding TVS diode, with a fast response time of 8ns. It dissipates energy up to 400W peak power and helps to protect sensititve electronic circuitry from voltage transients.
