The SA15A B0G is a transient voltage suppressor (TVS) diode designed specifically for protecting sensitive electronic systems from the effects of transient voltage disturbances. It is an ideal choice for systems vulnerable to spikes in voltage due to transients and other power quality events. The SA15A B0G is equipped with a rated voltage of 15 V and a maximum clamping voltage of 30 V.

The primary application of the SA15A B0G is for transient voltage suppression in electronic circuits. It is commonly used for automotive applications, such as overvoltage protection in sensing and control circuits, signal line protection, and automotive audio systems. Its wide operating temperature range of -55 ℃ to 150 ℃ makes it suitable for use in many industrial applications as well.

The working principle of the SA15A B0G is quite straightforward. It operates by clamping any transient voltages that exceed its rated voltage, and dissipating the energy of the transient in the form of heat. The diode is composed of two PN diodes connected in series and reverse biased to provide a high-current gain, allowing it to dissipate large amounts of energy. When the transient voltage is applied to the diode, the current generated is much higher than the normal current, leading to the majority of the energy being dissipated in the diode.

The SA15A B0G can handle up to 600 W of peak pulse power. The device has an off-state breakdown voltage of 65 V, a breakdown clamping voltage of 30 V, and a peak off-state current of 100 A. It also features an inherently low reverse leakage current and a capacitance of just 270 pF. This low capacitance ensures minimal interference with the signal that is being protected.

The SA15A B0G is designed to tolerate high levels of transient voltages without unwanted interference. It is an ideal choice for providing both overvoltage and ESD protection in automotive and industrial applications. Its compact surface mount package makes for easy integration into existing systems. The SA15A B0G is a reliable and cost-effective solution for protecting sensitive electronic systems from transient voltage disturbances.
