TVS - Diodes are a type of transient voltage protection device. They are used to protect equipment from voltage transients caused by electrostatic discharge (ESD), lightning, and other short-term voltage surges.

The 1.5KE400 is a unidirectional TVS diode, also known as a surge-stopping diode, which provides overvoltage protection. This component is mainly used in the automotive, telecommunications, medical, industrial, and military markets.

The 1.5KE400 uses a MOV (metal oxide varistor) to store, reduce, and direct excess electrical energy away from sensitive components. The diode works by quickly diverting any excess voltage away from the connected components. This happens by the MOV dissipating the energy as heat so that no damage is caused to the other parts.

The 1.5KE400 is constructed with a diode bridge network from four standard diodes. The MOV is connected across the two terminals of the diode bridge so that any voltage surplus is routed away from it appropriately. The 1.5KE400 is closely related to other protection devices, such as the 1N4007 diode, which works in a similar manner.

In terms of performance specifications, the 1.5KE400 has a breakdown voltage of 400V and a peak pulse power of 1500 watts. The operating current is limited to 150mA, meaning that the diode won’t overheat when protecting against a voltage surge. The operating temperature range of these devices is -55 to +125 degrees Celsius, and the storage temperature is -40 to +105 degrees Celsius.

The 1.5KE400 also has protection thresholds for surge current. This ensures that it does not become damaged by current surges of up to 30 amps peak. This level of protection makes them particularly well-suited for automotive applications including peak current protection for starter motors, and voltage protection for sensors, injectors, and other components.

The 1.5KE400 is also quite popular in telecommunications applications. In these applications, it is used to provide overvoltage protection and peak current protection in network nodes, and telecom switchboards, as well as to protect other sensitive components.

The 1.5KE400 is also used extensively in other applications, such as medical equipment, consumer and industrial electronics, military equipment, and avionics. It is designed to provide low-level overvoltage protection for LED displays, RFID circuits, I/O ports, and USB connectors.

The 1.5KE400 is designed to prevent any stress on the connected components that could lead to permanent damage and costly repair. As such, it is a critical component in many electronics, both in consumer products and in more specialized applications. The ability of the MOV in the device to quickly and effectively dissipate any excess electrical energy makes it an ideal choice for engineers who want to ensure their designs are properly protected from voltage transients.
