1.5CE24A BK

TVS - Diodes

The 1.5CE24A BK TVS (Transient Voltage Suppressor) Diode is a unidirectional solid state device that is predominantly used for overvoltage protection. The device is designed to clamp voltage transients to a safe level by connecting a low capacitance, low-inductance, high surge current discharge path between the two terminals. It is also known as voltage clamp diode or a surge diode, and is used in a variety of electronic systems for its exceptional ability to handle large numbers of frequently occurring transients. This article will focus on the application fields and working principle of the 1.5CE24A BK.

Application Fields

The 1.5CE24A BK is widely used in a variety of applications for its outstanding ESD (Electro-Static Discharge) and overvoltage protection capabilities. It is particularly suited for use in hybrid and automotive applications where delicate logic and sensing functions must be protected from lightning, electrostatic, and inductive activities. It is also used in telecommunications and networking equipment, consumer electronics, and handheld devices. Furthermore, the 1.5CE24A BK is considered ideal for high surge current, high-temperature, small clamped voltage, and high frequency applications.

Working Principle

The working principle of the 1.5CE24A BK involves two stages. The first stage involves the absorption of the excess overvoltage by utilizing the clamping action of the diode. In this stage, the diode will react to positive or negative overvoltage events by rapidly charging a capacitance located at the anode side of the diode to the desired voltage level. This stage is typically completed within a few nanoseconds depending on the voltage and current levels.

The second stage of the working principle involves the dissipation of the absorbed energy via conduction, commonly known as the “resolution phase”. In this phase, the absorbed energy will be discharged into the diode’s load and the device will then reset itself back to its normal operating voltage level. This process typically takes a few microseconds and ensures that the device is fully reset before the next overvoltage event occurs.

The 1.5CE24A BK is designed to provide a rapid response to transients thereby limiting the duration of the exposure to harmful events. This will ensure the proper functioning of the circuitry on which it is installed and will ultimately lead to improved reliability and system performance.

In conclusion, the 1.5CE24A BK is a reliable surge protection device used to protect microelectronics components from a variety of overvoltage conditions. It features a fast response time and low clamping voltage, making it suitable for a wide range of low power electronics applications. The device also provides a low ESR (Equivalent Series Resistance) path to safely dissipate the energy absorbed during transient events.
