SA40HE3/54 is a unidirectional four-terminal silicon-avalanche diode. This TVS diode is widely used in a wide range of electronic products to protect against damaging transients. SA40HE3/54 is a low capacitance diode designed to protect high speed data lines, such as USB, Ethernet, and HDMI ports from damaging electrical surges.

The TVS diode works through a fast avalanche breakdown process. When the transient voltage exceeds the diode\'s rated breakdown voltage, the diode acts as a short circuit between the anode and cathode and quickly dissipates the transient energy. The breakdown process happens within nanoseconds, so the device can quickly absorb the surge before it can cause any harm to the device\'s circuits.

SA40HE3/54 has a working voltage rating of 5.4V, a peak current rating of 6A, and a peak power rating of 25W. It has a low dynamic resistance of 3.2mΩ and low capacitance of 0.7pF. The device is packaged in small, heat-resistance, halogen-free SMT tapes.

The SA40HE3/54 diode is used in many electronic products to protect against ESD, EFT, and lightning strikes. It is also often applied in motor controllers, LED drivers, computers, digital cameras, and medical instruments. It is also used in automotive applications such as power supplies, relay circuits, traction control systems, and in-vehicle communication networks.

SA40HE3/54 is a low power, high speed TVS diode that can absorb and dissipate large amounts of transient energy. It is designed to provide quick response to surges and lasts thousands of hours in the field. With its high-reliability and low capacitance properties, the SA40HE3/54 is an excellent choice for designers seeking reliable surge protection for their products.
