TVS – Diodes

TVS (Transient Voltage Suppression) Diodes are special kinds of diodes used to protect electrical circuits from voltage spikes caused by the interference of inductive and/or capacitive loads. These spikes cause harmful damage to the circuits. TVS diodes can help protect against these spikes.SA33AHB0G is a widely used TVS diode in many electronics applications. It is a unidirectional, ultra low capacitance transient voltage suppressor diode. The name SA33AHB0G originates from the manufacturer’s name and the number that represents the manufactured date (ex: SA33AHB0G = SA33AHB0G-20180518).

SA33AHB0G Application Field and Working Principle

SA33AHB0G is a widely used TVS diode and has a wide range of applications, such as: automotive, medical, communication, consumer electronics, telecommunications, computer peripherals, and more.The working principle of SA33AHB0G is based on the “avalanche breakdown” principle. This process occurs when there is a sudden increase in the applied voltage and the open junction current rises rapidly. This rapid rise in current is called “avalanche,” which breaks down the barrier at the junction. The energy released during avalanche breakdown is dissipated as heat and the sudden increase in current is restricted. When the voltage spike is gone, the junction returns to its normal, off-state condition.The SA33AHB0G has a wide variety of performance characteristics such as: low capacitance, low clamping voltage, high transient current absorption, and low dynamic resistance. The maximum peak pulse current is 1500A, the maximum peak pulse power is 9W and the clamping voltage is 13V.The SA33AHB0G also has an excellent temperature and temperature cycling characteristics. The temperature range is from -40°C to +110°C and the temperature coefficient of capacitance (Cc) is less than -200 ppm/°C. The temperature cycling range is from -55°C to +125°C and the temperature cycling maximum capacitance change is ±1%.The SA33AHB0G has excellent ESD (Electrostatic Discharge) protection. The ESD protection is based on the avalanche principle which ensures the protection of very sensitive components from static electricity. It has a very low diversion current (<0.5A) and long-term ESD protection can be provided in the range of up to 25kV.In conclusion, the SA33AHB0G is a widely used TVS diode in many electronics applications. It has a wide range of performance characteristics, such as low capacitance, low clamping voltage, high transient current absorption, low dynamic resistance, excellent temperature and temperature cycling characteristics and excellent ESD protection. The SA33AHB0G can be used in a wide variety of applications such as automotive, medical, communication, consumer electronics, telecommunications, and computer peripherals.
