SMAJ90A TVS - Diodes

The SMAJ90A is a transient voltage suppressor diode designed for industrial and commercial applications. It is available in various package styles and has a fast response time. It is typically used for applications such as lightning and surge protection, ESD suppression, and line interference suppression.The SMAJ90A is a low capacitance, low leakage, and low-power clamping circuit designed to suppress transient voltage spikes in electrical lines. It is particularly suitable for protecting data lines from over-voltage or induced transient voltage spikes. It can also be used to protect power lines from voltage surges during power-on and power-off.The SMAJ90A has a breakdown voltage of 90V and is typically utilized for minimum operating voltages up to 33V. The peak pulse current can reach up to 127A. The transient suppression is accomplished by a Zener voltage breakdown. A wide range of operational temperature makes this diode suitable for a range of applications, including high-temperature automotive and industrial applications.The SMAJ90A is housed in a small surface-mount package, making it ideal for microelectronic applications. It does not require any external circuitry or components, allowing for more efficient system designs. It also uses significantly less power than other TVS diode options. This makes it suitable for low-power applications, such as automotive or consumer electronics applications.When using the SMAJ90A, the most important consideration is the peak pulse peak power rating. Peak pulse power refers to the peak power that the diode can safely handle at any given time. The peak pulse peak power rating of the SMAJ90A is 800W.To ensure safe operation within a system, it is also important to ensure that the circuit design takes into account the maximum power dissipation of the device. Failure to do so could result in the diode becoming damaged or failing to adequately protect the system.The SMAJ90A is also designed to reduce capacitance between its junction terminals. This reduces the amount of electromagnetic interference between the diode and other electrical components. This can help ensure system reliability by reducing the chances of circuit malfunction due to EMI. Furthermore, the device is designed with a low peak clamping voltage, which reduces the risk of induced voltage spikes throughout the circuit.In conclusion, the SMAJ90A is a highly reliable and efficient TVS diode which is capable of providing protection against voltage spikes and reducing EMI. Its wide range of operational temperature, low power consumption and low capacitance make it a suitable option for various applications.
