In electronic circuit design, transient voltage suppression (TVS) diodes are used to protect sensitive circuits from overvoltage damages. The SMAJ40A-QH TVS diode is the latest TVS diode developed by Diodes Incorporated. With its small package and low power dissipation, the SMAJ40A-QH allows for easy installation and provides customers with an efficient protection solution for several applications.

The SMAJ40A-QH has a working voltage of 40V, a peak power dissipation of 600W and a breakover voltage of 33V. It is designed to protect sensitive components from electrostatic discharge (ESD) and other transients that could lead to permanent damage. In addition, it provides important circuit protection such as protection against lead short circuit and overvoltage. It features low leakage current, low capacitance, and a fast response speed of 2.0µs above 10V.

Typical applications of the SMAJ40A-QH include USB and data ports, consumer electronics, home appliances, and automotive applications. It can also be used in a variety of industrial applications such as lighting, instrumentation, and process control. The small size, low power dissipation, and fast responding speed make it an ideal choice for a wide range of applications.

The SMAJ40A-QH operates on the principle of a "voltage driven switch". When the voltage across the device exceeds the breakover voltage, it will turn ON and provide effective protection. Once the voltage is reduced to a safe level, it will turn OFF to avoid damaging the circuit. The device can protect against a variety of different transients, including ESD, electrical fast transients (EFT), and lightning.

In addition, the SMAJ40A-QH features a low clamping voltage of 33V. This means that the device will clamp the voltage at or below this level, thus protecting the circuit from possible damage. The design also provides excellent capacitance and low capacitance for increased switch rate and reduced system noise.

The SMAJ40A-QH is an efficient and reliable choice for protecting sensitive components and circuits. With its small package and low power dissipation, it allows for easy installation and provides customers with an efficient solution for a variety of applications. The device is an ideal choice for circuit protection against ESD, EFT, and lightning, as well as providing overvoltage and capacitance protection.
