1KSMBJ24CA Circuit Protection

TVS (transient voltage suppressor) diodes are special components designed to protect sensitive electronic components by limiting transient voltage spikes (electrical overshoots, spikes, or surges) in power supplies, protecting against electrostatic discharge (ESD) and blocking transients from entering a power source. In this article, we will discuss the application field and working principle of TVS diode 1KSMBJ24CA.

Working Principle of TVS Diodes

The operation of a TVS diode can be explained using the P-N junction physical structure. When the input voltage is lower than the diode\'s peak working voltage, the diode is in a reverse-biased state, where the cathode is at a higher potential than the anode. Since the cathode and the anode are separated by an insulator, no current can flow in the diode.

When the input voltage exceeds the peak working voltage, the current starts to flow through the diode, creating a short circuit. This allows the excess energy to dissipate and prevents the input voltage from rising further. This is the primary working principle of a TVS diode, where it limits the peak voltage level and effectively protects the electronic device from damage.

Conclusion

The 1KSMBJ24CA TVS diode is a reliable component for a variety of applications, including telecommunications, industrial interface, and consumer electronics. This diode can handle transient voltages up to 160V and can withstand up to 1500 Watts of power.
