TVS - Diodes

TVS diodes provide transient voltage suppression, a form of overvoltage protection, for a variety of electronic systems. A TVS diode is used to reduce the effects of inductive and capacitive voltages that can enter a system due to electromagnetic, electrostatic or radio frequency interference (EMI, ESD, or RFI). This protects the system against voltage spikes and surges such as lightening strikes and inductive loads.

The SMAJ45CA-M3/5A TVS diode is designed to protect sensitive electronic equipment from voltage spikes and surges. The diode features a low capacitance, fast response time, and a low stand-off voltage. The diode has a reverse stand-off voltage of 5-45 volts and a maximum peak pulse current of 4500 amps. It is also RoHS compliant and UL 94V-0 rated for flammability.

The diode application involves connecting the diode between an anode and a cathode, across the voltage source to be protected. The anode lead of the diode is connected to a positive voltage, and the cathode lead is connected to a negative voltage. When a positive voltage spike occurs, the diode redirects that current away from the equipment. When a negative voltage spike occurs, the diode redirects current back into the line and therefore preventing the transient from entering the system.

The SMAJ45CA-M3/5A is a bidirectional diode and is made from a silicon avalanche technology. It has an effective clamping voltage of 45 volts and a peak pulse power rating of 395 watts. The diode features an industry-standard through-hole design, making it easy to install in surface mount applications. The diode is also capable of dissipating large peak pulse currents and is capable of withstanding high voltages, making it ideal for transient voltage suppression applications.

The SMAJ45CA-M3/5A diode can be used in a number of different applications including motor controllers, data lines, power supplies, and LED lighting systems. As a general voltage spike protection device, the diode is approved for use in a wide range of electronic devices from consumer electronics to industrial machinery.

TVS diodes provide an effective way to protect against transient overvoltages. The SMAJ45CA-M3/5A diode is a versatile, high-performance device that is suitable for use in a variety of applications. Its low capacitance, high peak pulse current ratings, and UL 94V-0 flame rating make it a reliable choice for transient voltage suppression.
