Introduction to TVS – Diodes

A TVS (transient voltage suppression) diode, also known as a "transient voltage suppressor" or "transorb," is an electrical component that is designed to prevent a sudden electrical surge from damaging sensitive components in electronic systems. As the word diode implies, it is a two-terminal device, consisting of an anode and cathode. TVS diodes are designed to absorb transient voltage, and can be used to protect analog and digital circuits from voltage spikes.

Application Fields of MXLSMBJ16AE3

The MXLSMBJ16AE3 is a TVS diode designed to protect a wide variety of applications, ranging from computer and telecom systems, automotive, security, and medical products, to instrumentation and consumer electronic products. It has a low dynamic resistance of 0.0005 Ohm and can sustain a high pulse current of up to 5KA (8/20µs pulse width). With its fast response time and excellent clamping characteristics, it offers reliable protection from voltage transients.This diode has a wide breakdown voltage range of 10-21V, so it can fit a variety of application scenarios. It is available in both surface mount and through-hole packages, which allows it to be used even in space limited applications. In addition, it has an electrostatic discharge rating of > 20kV, making it suitable in applications where high ESD immunity is required. Its operating temperature range is -55 deg C to +125 deg C, further increasing its versatility.

Working Principle of MXLSMBJ16AE3

The working principle of the MXLSMBJ16AE3 is based on the diode rule. When the voltage spike or transient exceeds the breakdown voltage of the diode, it starts conducting to protect the device from being damaged. The diode then safely conducts the excess current away from the circuit. When a transient spike occurs, the MXLSMBJ16AE3 absorbs the energy of the surge, and the voltage at both terminals of the diode quickly rises to the "clamping level." This level is determined by the breakdown voltage of the diode. As the voltage rises, the current starts flowing in the reverse direction, and the energy is dissipated as heat. Once the transient has passed, the diode switches off and the voltage across it returns to normal. The MXLSMBJ16AE3 is designed to be able to instantly absorb the high energy of the transient spike while operating at temperatures up to +125°C.

Conclusion

The use of TVS diodes such as the MXLSMBJ16AE3 is becoming increasingly important as technology becomes more sophisticated and delicate, and design constraints become more stringent. It is a simple, cost-effective solution for protecting electronic devices from voltage transients. The MXLSMBJ16AE3 is engineered to be highly reliable and able to withstand high pulse currents and high temperatures. Its wide breakdown voltage range and excellent clamping performance make it an ideal choice for applications requiring transient voltage protection.
