TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are designed to protect electronics from electrical over-stress or damage from external transients, electrostatic discharges or electrical fluctuations. The SA45CAHA0G is specifically designed to protect against electrostatic discharges. It has a low capacitance of 0.5pF, and is available in SOT23 and DFN packages.

Application field of SA45CAHA0G

The SA45CAHA0G is designed to protect against ESD events in consumer electronics such as PCs, tablets, and mobile phones. It is suitable for consumer equipment, industrial equipment and automotive applications. It is also used in medical, audio and audio-visual equipment. In addition, it can be used in portable instruments, portable data storage, gaming systems, and factory automation.

Working Principle of SA45CAHA0G

The SA45CAHA0G is designed to protect against electrostatic discharges and other transient voltage events by clamping the voltage level. It works by diverting overvoltage currents away from sensitive electronics. When the TVS diode reaches its peak voltaic rating, the diode turns a high surge of current into a short circuit. This causes the voltage to drop and thus prevents the overvoltage from damaging sensitive electronics.

The SA45CAHA0G has a fast reaction time of 0.5 ns, which enables the diode to clap the voltage in time before it damages the electronic systems. Its high surge capability passed the IEC 61000-4-2 Level 4 standard, meaning it is capable of withstanding 8 kV discharges of air gap.

The SA45CAHA0G is widely used due to its ease of use and aesthetics. It has an operating temperature range of -55°C to +125°C and can be integrated into a wide variety of applications. It is one of the best solutions for protecting sensitive electronics from electrostatic discharges and other transient voltage events.
