A transient voltage suppressor diode, also commonly referred to as a TVS or a “Transient Voltage Suppression Diode”, is a specialty type of diode specifically designed for protecting against electrical transients in power supplies and data transmission lines. The 1V5KE400A diode is a zener diode that helps regulate and control electrical surges, ensuring that the circuit and components are not damaged from too much current.

Application

The 1V5KE400A is used in circuit design to protect from over-voltage issues caused by ESD (electrostatic discharge) when used in electronic applications. The 1V5KE400A is also used in motor control, telecommunications, automotive, and computing systems, as well as in other applications such as surge protectors. The 1V5KE400A is ideal for slow-response sources such as printed circuit boards as well as fast-response sources such as data lines.

Working Principle

The 1V5KE400A is a zener diode, which means it is able to conduct current in the forward direction when a voltage is applied to it. When the voltage reaches the Zener breakdown voltage, the diode begins to conduct in the reverse direction, allowing the excess voltage to be discharged to ground. This helps to protect signal lines, power supplies and other components in the circuit from over-voltage issues that can lead to malfunctions or even complete destruction of the system.

The 1V5KE400A is designed to handle repetitive reverse surge voltages up to 400V, providing reliable protection for sensitive components and systems. The 1V5KE400A has a low maximum reverse leakage current of 1.0 µA, and a maximum peak pulse power dissipation of 125W. The 1V5KE400A also has a maximum storage temperature of 150°C and an operating temperature range of -50°C to +125°C.

Benefits

The main benefit of the 1V5KE400A is that it is able to protect both the signal lines and power supplies from over-voltage issues. This makes the 1V5KE400A an ideal choice for circuit design, as it helps to ensure that the system is adequately protected from any spikes or changes in voltage. Additionally, the 1V5KE400A is able to handle repetitive reverse surge voltages up to 400V, making it suitable for applications such as motor control, telecommunications, automotive, and computing systems.

Conclusion

The 1V5KE400A is a specialized diode designed to protect against electrical transients in power supplies and data transmission lines. The 1V5KE400A is ideal for slow and fast-response sources, as it is able to handle repetitive reverse surge voltages up to 400V. The 1V5KE400A is used in applications such as motor control, telecommunications, automotive, and computing systems, offering reliable protection for signal lines and power supplies.
