A TVS diode, also known as a transient voltage suppressor, is an electronic component designed to protect against overvoltage and electrostatic discharge that can damage other electrical components. The SMLJ26CA-Q is a unidirectional transient voltage suppressor (TVS) diode with a maximum peak pulse power of 500 watts and an operating temperature range of -40℃ to +85℃. This type of diode is suitable for use in television sets, computer systems, motor control systems, and automotive electronics.

Application Field of SMLJ26CA-Q

The SMLJ26CA-Q type is designed to protect against voltage transients such as surge, induced lightning, and electrostatic discharge. This type of diode is often used in television sets, computer systems, motor control systems, and automotive electronics where overvoltage and electrostatic discharge can cause component damage. This diode will clamp the voltage to a low level and is an ideal choice for protecting sensitive electronic components from damaging transients.

Working Principle of SMLJ26CA-Q

The SMLJ26CA-Q diode is a unidirectional transient voltage suppressor (TVS) diode with a peak pulse power of 500 watts. It works to protect against overvoltage and electrostatic discharge, by clamping the voltage to a low level. This diode has a low capacitance and can easily be integrated into a circuit. The diode is designed to fail in the open configuration, creating a low resistance path and ensuring that no other components are damaged by the overvoltage.

When an over-voltage occurs, the minority-charge carriers, and hence current, will be injected from the p-side to the n-side of the diode junction, resulting in a voltage-clamping action. This action limits the amount of voltage reaching the device it is protecting and prevents any damage. The diode also has a low leakage current making it suitable for use in applications where high capacitive loads are present, such as computer systems.

Conclusion

The SMLJ26CA-Q TVS diode is a low-capacitance, unidirectional transient voltage suppressor that is designed to effectively protect against overvoltage and electrostatic discharge. This diode is suitable for a range of applications, such as television sets, computer systems, motor control systems, and automotive electronics, and its low leakage current allows for reliable operation in high capacitive load applications. Finally, its unique design features allow it to protect against voltage transients such as surge, induced lightning, and electrostatic discharge.
