Electronic components for transient voltage suppression are critical for protecting a variety of electronic devices and circuits from the damaging effects of voltage spikes. The MAP5KE9.0A from Vishay Semiconductor is a silicon-based transient voltage suppression diode. This diode combines low cost and high ESD protection, and with its low leakage current is an efficient and reliable solution for electronic devices in automotive, industrial, and consumer applications.

The MAP5KE9.0A has an 7-in-1 Ceramic ESD protection circuit that includes five ultra-low capacitance TVS diodes, and two ultra-low capacitance filter inductors. It is designed to provide protection for data lines and power lines from electrostatic discharge (ESD) and electrical fast transients (EFT) events. The device includes over-voltage and over-current protection, as well as an integrated reset circuit.

The MAP5KE9.0A works by clamping the voltage on the input line (the “protected line”) to a safe level. This is accomplished by a process called Avalanche Breakdown. In this process, the junction between two opposite-type conductors is placed in a reverse bias, and the diode begins to turn on when the applied voltage is high enough. At this point, the device’s current-limiting properties come into play, and the remaining energy is absorbed by the clamp. The protected line is then limited to a safe voltage level, preventing the damage of the protected device.

The MAP5KE9.0A can operate over the temperature range of -40°C to +85°C, and it has a maximum clamping voltage of 12V. The device has an insulation rating of 4.4 x 108 ohms and a storage temperature of -55°C to +125°C. It also has a maximum continuous operating voltage of 9V and a repetitive peak pulse power of 200W. The device is AEC-Q101 compliant.

The MAP5KE9.0A is a versatile device and is suitable for use in a variety of applications. It can be used for signal and data line protection in automotive and automotive-related applications, such as tire pressure monitoring systems, sensors, communication systems, infotainment systems, power window controllers, and anti-lock braking systems. It can also be used in industrial applications such as motor protection, communications systems, lighting control systems, AC/DC power supplies, CCTV security, and home automation.

Due to its superior features, the MAP5KE9.0A is ideal for protecting a variety of electronic devices and circuits from the damaging effects of voltage spikes. It is a reliable and efficient solution for automotive, industrial, and consumer applications, providing the highest level of protection with a low cost and low leakage current.
