SM8S12ATHE3/I Application Field and Working Principle

Transient Voltage Suppressors (TVS) are components used to defend against voltage transients. They are typically used to protect electronic circuits from damage due to over-voltage transients such as electrostatic discharge (ESD) events and voltage spikes from power sources. TVS diodes are one of the most common types of transient suppressor components. The SM8S12ATHE3/I is a TVS diode which offers improved surge capability and low leakage current.

Applications of SM8S12ATHE3/I

The SM8S12ATHE3/I is a Transient Voltage Suppressor (TVS) diode used to protect against electrical overstress from ESD, surge and related events. The device is typically used in consumer electronics applications such as cell phones, media players, digital cameras, and PDAs. It is also well-suited for professional communications equipment and industrial controls. The SM8S12ATHE3/I is a low-leakage device that provides superior surge capability with minimal internal capacitance. It is available in two package configurations, the SMA single-line package and the SMB dual-line package.

Working Principle of SM8S12ATHE3/I

The SM8S12ATHE3/I is designed to protect against electrostatic discharge (ESD) and voltage surges. The device is a bidirectional 100V TVS diode constructed using avalanche technology. It is composed of two back-to-back diodes with a voltage breakdown voltage of 100V. When the voltage across the device exceeds its breakdown voltage, an avalanche occurs which causes the current to reduce. This limits the voltage across the diode to its specified voltage clamping level. The device is internally clamped and can protect circuits from various voltage transients. The SM8S12ATHE3/I also offers improved surge capability over traditional unidirectional TVS devices.

Advantages of SM8S12ATHE3/I

The SM8S12ATHE3/I offers a number of advantages compared to other types of transient voltage suppressors. It is a low-leakage device with minimal internal capacitance that provides superior surge capability. The device is bidirectional and can also be configured to provide both positive and negative voltage suppression. The SM8S12ATHE3/I is available in a small package size, making it ideal for use in portable devices. Additionally, the device is capable of handling high peak current pulses and can protect circuits from a wide range of voltage transients.

Conclusion

The SM8S12ATHE3/I is an important device for protecting electronic circuits from over-voltage transients. It is a low-leakage diode constructed using avalanche technology that offers improved surge capability and minimal internal capacitance. The device is typically used in consumer and professional equipment to protect against ESD, surge and related events. It is available in two package configurations, the SMA single-line package and the SMB dual-line package, and offers a number of benefits over traditional unidirectional TVS devices.
