TVS (Transient Voltage Suppressor) diodes are solid state devices used to protect sensitive electronic equipment from voltage and current surges, spikes, and specular dispersions. These surges are caused mainly by lightning strikes and electrostatic discharges. TVS diodes are used for virtually all circuits in aviation and defense-related applications including aircraft, automotive, computer, communication and medical electronics. The P6SMB15CAT3, manufactured by Littelfuse, is a popular TVS diode type, which is designed to provide overvoltage protection to sensitive electronic equipment.

The P6SMB15CAT3 is a single channel, bidirectional device. It is designed and rated to be able to withstand voltage transients up to 15000W peak pulse power per line (tp = 8/20µs). The P6SMB15CAT3 offers the following features: low leakage current of ≤ 50nmA; low clamping voltage of 33.3V@8A;; a fast response time of ≤ 1.05ns; and a high temperature rating of -55 to +175°C. The P6SMB15CAT3 also has built-in ESD protection, which helps to protect circuits from electrostatic discharge.

The P6SMB15CAT3 is commonly used in various aviation and defense-related applications such as aircraft, automotive, computer, communication and medical electronics. It is especially well suited for applications that require protection from transient voltage spikes which can be caused by lightning strikes, electrostatic discharge and overvoltage conditions. The P6SMB15CAT3 can be used to prevent electronic components from damage due to overvoltage and voltage transients. It is also suitable for connecting to digital and analog circuits that require protection from these transients.

The working principle behind a TVS diode is simple. When an overvoltage condition occurs, such as a lightning strike or electrostatic discharge, the TVS diode will climber to absorb the excess voltage. The current from the overvoltage will be redirected and dissipated through the TVS diode instead of the sensitive components, thus protecting them from damage. The P6SMB15CAT3 has a low clamping voltage of 33.3V@ 8Aand a fast response time of 1.05ns, which ensures that the excess voltage is quickly discharged, and the protected circuit is not damaged.

The P6SMB15CAT3 provides reliable protection from overvoltage and voltage transients for numerous applications. It can be used to protect sensitive electronic components from being damaged due to surges, spikes, and specular dispersions. The P6SMB15CAT3 also offers low leakage current, low clamping voltage and fast response time, therefore enabling it to effectively protect systems and circuits from being damaged due to overvoltage and voltage transients.
