Introduction

AOZ8311DI-26 is a transient voltage suppression (TVS) diode, which can efficiently protect sensitive electrical components from surges and overloads. It is mainly used in automotive electrical systems, such as power and steering systems, to protect them from voltage spikes. The AOZ8311DI-26 is also available in combination with a MOSFET, giving it the added advantage of providing switching capability as well.

Application Field

AOZ8311DI-26 is used in automobile applications such as powertrain, engine control, transmission, braking, and steering systems. It is also used in industrial applications for critical power supply applications such as control systems, industrial equipment, and critical components of consumer and industrial electronics.The AOZ8311DI-26 provides superior protection for components and systems in harsh automotive and industrial environments. It is suitable for industries ranging from automotive to consumer and industrial electronics, where the need for extremely reliable over-voltage protection is essential.

Working Principle

The AOZ8311DI-26 is a TVS diode that is triggered when its threshold (breakdown) voltage is exceeded. The diode is designed to absorb surges and clamp them to a safe voltage level to prevent potential damage to equipment.When an over-voltage occurs, the AOZ8311DI-26 dissipates the additional current into its internal junction until it reaches a safe voltage level. The diode then returns to its normal, forward-biased, low-leakage state. This makes the AOZ8311DI-26 an ideal solution for applications that require efficient over-voltage protection. The TVS diode is also designed to dissipate high power ramps or over-voltages on supply rails and signal ground lines. It also has a low capacitance to ensure low signal distortion and low insertion loss for signal lines. Additionally, it has a fast-acting surge clamping capability, which makes it suitable for use in applications with high-speed transients.

Conclusion

The AOZ8311DI-26 is a TVS diode that provides superior protection for automotive and industrial systems. It can dissipate surges and clamp them to a safe voltage level, ensuring reliable operation and protecting sensitive components from damage. The AOZ8311DI-26 is also available in combination with MOSFETs, giving it the benefit of providing both surge protection and switching capabilities.
