TVs, or transient voltage suppressors, are components that protect circuits against damage due to electrical overvoltage and transient pulses. Unlike fuses, they do not require replacement after use. TVSs can be used in a variety of applications, including automotive, industrial, telecommunications, and consumer electronics. These components typically consist of a diode, an SCR, a Zener diode, or a combination of all three. The MXLCE64A is one such component, and it is specifically designed to protect automotive electronic control modules (ECMs) and electronic engine control systems (ECSs) from surges due to EMI, as well as short-circuit conditions.

The MXLCE64A is a unidirectional, high-speed diode with an SCR and Zener diode integrated into its design. The diode part provides voltage protection and the SCR and Zener diode provide current protection. It has an operating voltage of 18 V and a peak working power of 350 mW. It is also designed with a low dynamic resistance, which allows it to be used in automotive electronic control systems. The diode is designed with an ESD tolerant performance, and it offers increased protection against overvoltage conditions. The component is designed to be used in circuits operating at an ambient temperature range of 125°C to 150°C, and it is available in a DO-214AC package.

In terms of operation, the MXLCE64A works by providing low on-state resistance and fast switching. This ensures that it can quickly react to an overvoltage condition and protect the circuit from damage. This diode also has an impedance that is designed to not interfere with signals being transmitted in the circuits it is protecting. When the voltage rises above the specified clamping voltage, the device will start conducting current and the voltage will be safely diverted throughout the diode. This reduces the voltage on the protected line back down to a safe level. The device will then continue to monitor the voltage on the line and turn off when the voltage drops below the specified clamping voltage.

The MXLCE64A is a versatile and reliable diode that can provide effective protection for automotive electronic systems. It is designed for use in harsh operating environments, and it features an increased tolerance to ESD, which allows it to provide superior protection compared to other TVSs. The diode has a low on-state resistance and a fast switching time, which makes it ideal for use in automotive systems where overvoltage protection is critical. It is also available in a variety of package types, making it easy to use in a variety of applications.
