TVS (Transient Voltage Suppressors) diodes, also known as transient voltage suppressors, are semiconductor devices mainly used to counter the damaging effects of voltage transients, also known as surges, by changing them into harmless levels. The SMAJ70A-13-F transient voltage suppressor diode is such an example. This device is designed to reduce voltage transients and overcurrent to safer levels, making it ideal for application in various areas: from automotive components, to consumer electronics and heavy industrial systems.

Application Field

The SMAJ70A-13-F diode provides an electromagnetic immunity of 70V, making it suitable for automotive, consumer, and industrial applications including power supplies, microprocessors, programmable controllers, signal lines and even other sensitive components. It\'s suitable to application in low overvoltage protection, line surge suppression and other medium overvoltage protection for all industrial areas. With a high surge capability of 700 Watts, it is ideal for applications that require high pulse current capability and operation.

Working Principle

The principle of operation in the SMAJ70A-13-F transient voltage suppressor diode is based on its internal MOSFET-like structure. When the device is subjected to a voltage that is higher than its rated breakdown voltage, the MOSFET-like structure begins to conduct, allowing current to flow through the device and dissipating the excessive pulse. This allows for a high current capability over a long period of time with a low operating power dissipation.

In comparison to a traditional box-style transient voltage suppressor diode, the SMAJ70A-13-F is constructed in an axial package with an internal thermally-enhanced copper-lead frame. This allows for a higher current capability and better thermal performance than is attainable with a traditional style device.

In addition, the device is also designed with a protective base which helps to protect it from ESD (ElectroStatic Discharge) and other harmful environmental effects. This provides a much longer operational life and reliability than a traditional TVS diode.

Conclusion

The SMAJ70A-13-F is an ideal combination of low operating power dissipation and high current capability. Due to its ability to reduce voltage transients and overcurrent to safer levels, it is suitable for various application in automotive, consumer electronics, and other industrial systems. In addition, its thermally-enhanced copper-lead frame and protective base also increase its reliability and provide a longer operational life.
