TVS-Diodes, also known as Transient Voltage Suppressors, are devices designed to protect against electrical stress caused by transient impulses such as ESD, EFT and inductive kick-back. MA15KP40CAE3 is a type of TVS-Diode designed for ESD protection in applications that require ultra-low slot capacitance and high voltage protection.

The MA15KP40CAE3 is an epitaxial structure device. It has a contact spread of 0.21mm x 0.33mm, a typical typical resistance- capacitance (RC) of 8ohm/401pF, and a maximum capacitance of 400pF. It offers low capacitance for ESD and lightning surge protection, and excellent clamping capability. It is ideal for board level protection of sensitive components and high speed digital circuits.

The MA15KP40CAE3 is designed to provide protection in the following application fields:

• Telecom lines
• LAN & WAN systems
• USB & Firewire
• Notebook & Desktop PCs
• Instrumentation
• Mobile phones & PDA’s

The working principle of the MA15KP40CAE3 device is based on the zener action characteristics of the device when it is subjected to a high voltage or electrical shock. When the voltage across the device exceeds the breakdown voltage of the device, the device starts conducting, thus limiting the voltage. In this process, the energy of the transient is absorbed and dissipated in the form of heat. Due to its low capacitance, the MA15KP40CAE3 device has an excellent response time in comparison to other TVS-Diodes.

The MA15KP40CAE3 has a wide reverse breakdown voltage range and low clamping voltage. This ensures less voltage surge through the electrical circuit and prevents the failure of sensitive electrical components. Furthermore, it is designed with a 2.5V zener diode, for protection against overvoltage transients.

The MA15KP40CAE3 is RoHS compliant and features an operating and storage temperature range of -65°C to +175°C. The device is available in a variety of packages, such as SMF, nanoSMF, and LGA. It is an excellent choice for ESD protection and is widely used in high speed applications.
