Introduction

Transient Voltage Suppression, or TVS, diode, is a specific type of diode aimed at providing protection against voltage transients that can cause disturbances in electrical circuits, interfering with the circuit\'s intended operation. Such transients can be caused by excessive current or voltage, outside environmental factors such as electromagnetic interference, or even lightning. TVS diodes provide a fast and effective means of protecting against such electrical disturbances. The SMBJ33CA-Q diode is a transient voltage suppresser designed to protect sensitive circuit components against excessive transient voltages.

Application Field

The SMBJ33CA-Q TVS diode is specifically designed for applications with high peak pulse power requirements in the 5V to 36V range. It is a surface mount diode package with low capacitance and low equivalent series resistance that allows for fast response times with a low clamping voltage. It is an ideal solution for applications with a high level of transient voltage and irregular waveforms, such as those found in automotive, consumer electronics, and industrial settings. Typical applications include automotive electronic control units, power supplies, and other consumer electronic products where transient protection is needed.

Working Principle

The SMBJ33CA-Q diode is designed to absorb the energy in the transient voltage, thereby “clamping” the voltage which prevents any further surges in the voltage. The diode works by redirecting the excess energy to ground, allowing the current to flow away from vulnerable components while also suppressing the voltage. The maximum peak power that the diode can handle is determined by its energy capability (IC) and its breakdown voltage (VBR).When a voltage transient hits the diode, the diode responds by absorbing the energy, which is then dissipated to ground. This dissipated energy is made possible by its low capacitance, which reduces the resistance to the current, and its fast response time, which allows it to clamp the voltage before it can cause damage to sensitive components. The current is diverted through the diode to ground, meaning that it can safely dissipate the energy instead of it flowing through the vulnerable components in the circuit.

Conclusion

The SMBJ33CA-Q from Central Semiconductor is a high-performance TVS diode designed to provide reliable protection against transient voltage spikes in a range of 5V to 36V. It features low capacitance, low equivalent series resistance, and a fast response time that make it perfectly suited for use in high power and irregular waveform applications. The diode works by dealing with the energy in the transient voltage, absorbing it and then redirecting the energy to ground. This helps protect sensitive components in the circuit from the risk of damage caused by excessive voltage.
