Transient voltage surge suppressor (TVS) diodes are designed for over-voltage protection (OVP) applications and are a popular line of defense against harsher-than-normal electrical environments. The MX1.5KE110CAE3 is a unidirectional dual-line device with enhanced ESD ratings that is used in both consumer and industrial electronic equipment. This article will discuss the application fields and working principle of the MX1.5KE110CAE3.

The MX1.5KE110CAE3 is suitable for protecting any two different input signals, such as digital and analog lines. The device is optimized for protecting a 5.5V logic input signal with an 8V analog signal or a 5V logic input signal with a 2V analog signal. The device features a wide breakdown voltage range, from 6V to 12V, and a ESD rating of up to 25kV. This makes the MX1.5KE110CAE3 perfect for a variety of applications where high-voltage protection is needed, such as digital and analog telecommunication lines, computers and peripherals, automotive and military equipment, and audiovisual equipment.

The working principle of the MX1.5KE110CAE3 is based on the simple concept of voltage clamps. When the voltage increases above the device’s breakdown range, the voltage is clamped at a constant level determined by the device’s internal circuit parameters. This clamped voltage is then further dissipated through the device’s internal resistance. This prevents any further voltage surge from damaging the device or other connected components.

The MX1.5KE110CAE3 also features surge and clamp current ratings. The device’s peak surge current (IPP) is guaranteed up to 1.5A, while the clamp current (IC) is maintained within the range of 400mA – 500mA. This is important because the device will be able to adequately protect equipment from high-current surges.

In addition to its improved transient protection, the MX1.5KE110CAE3 also features a reverse breakdown voltage (VBR) of 11.2V and a working current (IW) of 25mA. The device also has a maximum peak pulse power dissipation (PPPM) of 600W and a junction-to-ambient thermal resistance (RθJA) of 150°C/W. Furthermore, the device is lead-free and RoHS compliant.

In summary, the MX1.5KE110CAE3 is a unidirectional dual-line TVS diode that is designed for over-voltage protection applications. The device has a wide breakdown voltage range and an impressive ESD rating of up to 25kV. It also features surge and clamp current ratings that are adequate for protecting equipment from high-current surges. Furthermore, the device also features a reverse breakdown voltage, a working current, maximum peak pulse power dissipation, and a junction-to-ambient thermal resistance. The device is also lead-free and RoHS compliant. Therefore, the device is an ideal choice for protecting digital and analog telecommunication lines, computers and peripherals, automotive and military equipment, and audiovisual equipment against potentially damaging voltage surges.
