TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are devices specifically designed to protect the circuits from voltage spikes and electrical transients. These components come with a variety of packages and have wide range of voltage suppressions. In electronics, they generally act as suppressors of overvoltages. Depending on their type, some diodes can also be used as surge absorbers.

SA48AHA0G is a member of TVS diodes. This product is designed and developed to meet the requirements of automotive electronic systems protection, industrial equipment, and LED applications. It is mainly used in applications such as Automotive and Telecommunication.

SA48AHA0G is a hybriddiode, which has two parts in the same package. It iscomposed of PN5054 single-channel over-voltage protection diodes and PN1417Z bipolar transistors. Its working principle is shown asfollows. It has a rated peak pulse power of 48 W (10/1000 μs). It has a clamping voltage of 11 V at IPP = 48 A. When an overvoltage greater than this clamping voltage appears, PN5054 will conduct and the reverse current flows through the PN5054, reducing the voltage across the protected device. In addition, the PN1417Z keeps conducting, providing further protection.

The other characteristics of SA48AHA0G are relatively high stability over temperature, its low leakage current, and its highextended temperature range up to 150˚C. Its electrical characteristics include repetitive peak pulse power, peak pulse current, peak pulse voltage, dynamic resistance, and forwardvoltage drop-off voltage.

SA48AHA0G is a highly valuable component for various industrial and automotive applications. It provides efficient protection for electronic devices against surges, transients, and various overvoltages. Moreover, it has an excellent ESD protection of 25 kV to protect from electrostatic discharge. SA48AHA0G is also UL Recognized, and meets the requirements of a variety of standards, such as AEC-Q101-R0, IEC-60134-2, and ISO 7637-2.

In conclusion, SA48AHA0G is a perfect device for protection applications in the automotive and telecommunication industries. It has a high efficiency performance, excellent ESD protection, and wide temperature range up to 150˚C. This product meets the requirements of various standards to ensure its reliability in real life applications.
