Transient voltage suppressor (TVS) diodes protect electronic components from erratic overvoltages by suppressing voltage spikes. The SMB10J26HE3/52 is a subminiature bidirectional, 600W transient voltage suppressor. It is ideally suited for automated production applications, such as consumer electronics, power supplies, and medical devices. This article will discuss the application fields and working principle of the SMB10J26HE3/52.

The SMB10J26HE3/52 has a low clamping voltage and a very short response time, making it the perfect choice for protection against electrostatic discharges (ESD) and other voltage transients. Additionally, it has a low dynamic resistance, allowing it to absorb higher energy levels without significant voltage increases.

The SMB10J26HE3/52 is designed for a wide variety of applications, including power supplies, LED lighting, automotive electronics, telecommunications equipment, medical devices, and consumer electronics. It can also be used in commercial and military applications. It is an ideal choice for applications that require protection from transient events such as lightning strikes, electrostatic discharges, and voltage induced power surges.

The SMB10J26HE3/52 employs a reverse-biased zener diode/silicon avalanche diode junction, which clamps the voltage across the element and limits any potential overvoltage. A reverse-biased zener diode/silicon avalanche diode junction works by allowing electric current to flow in one direction, while blocking it in other directions. This helps protect the element and limit the voltage across it.

When an overvoltage is applied to the junction, the zener electrostatic field increases, triggering the avalanche breakdown of the junction and allowing current to flow through the diode. This increases the voltage drop across the diode and reduces the potential overvoltage. The diode then becomes a low impedance conductor until the overvoltage has been dissipated.

The SMB10J26HE3/52 is rated for 600W transient surge events with a voltage clamping of 13.1V. It has a peak pulse power of 1.2kW and a peak pulse current of 6.7A. It is capable of handling a current of up to 5A for long periods of time and has a low dynamic resistance of 0.0017 ohms. Additionally, it has a low turn-on voltage of 6V and a fast turn-on time of less than 1 nanosecond.

In summary, the SMB10J26HE3/52 is a subminiature bidirectional, 600W transient voltage suppressor ideal for applications such as LED lighting, automotive electronics, telecommunications equipment, medical devices, and consumer electronics. It uses a reverse-biased zener diode/silicon avalanche diode junction to protect against electrostatic discharges and other voltage transients, and has a low clamping voltage, low dynamic resistance, and a fast turn-on time. Additionally, it is rated for 600W transient surge events with a peak pulse power of 1.2kW and a peak pulse current of 6.7A.
