TVS - Diodes

TVS (Transient Voltage Suppression) diodes are used to protect electrical equipment from over-voltage shocks, spikes, and surges. SMBJ17CA-13-F is a type of TVS diode. It is a bi-directional Unidirectional TVS Diode that can protect against up to 17.5 volts of positive voltage, and up to 13 volts of negative reverse polarity. It is made up of a pair of zener diodes connected in series with a silicon diode.

Application Field

SMBJ17CA-13-F TVS diode has wide ranging applications in the electronics and power industry, such as for in-vehicle systems, industrial automation, consumer electronics, telecom, and power supplies. It can be used to protect any system from unwanted fluctuations in input voltage. It is used for such applications because it can provide a secure solution with minimal power losses.

Working Principle

SMBJ17CA-13-F TVS diodes work by limiting the voltage that can flow through the device. In normal conditions, when the input voltage is below 17.5 volts, the diode does not conduct, and the input signal passes through the device without loss. However, when the input voltage exceeds 17.5 volts, the diode conducts, which has the effect of clamping the voltage at that level.

The diode also has the effect of diverting any reverse polarity currents away from the device. So, if there is a negative voltage spike, the diode will conduct and protect the device from harm.

The SMBJ17CA-13-F TVS diode is designed to work accurately and reliably in a wide range of temperatures. It can be used in temperatures between -55 °C and +125 °C. The diode also offers excellent attenuation resistance against repeated surge events.

The SMBJ17CA-13-F is a reliable and cost-effective solution for protecting electrical equipment from over-voltage shocks, spikes, or surges. It is designed to provide precise protection and to minimize any power losses.
