The MAP5KE40CA is an ultra-low capacitance, bidirectional Transient Voltage Suppressor (TVS) diode designed to provide protection against transient surges in demanding applications. With excellent ESD protection and EMI suppression characteristics, this product is ideally suited for high-speed port protection, automotive applications, and other harsh environments.

The MAP5KE40CA is designed to protect against damaging transient surges by clamping triggered voltage lower than the breakdown voltage. This device is provided in an industry-standard SOT-23 package, and is rated for a 5,400 W peak pulse current and an 8.2V breakdown voltage. It features a low capacitance of 1.1 pF, ensuring excellent performance and protection while also making it suitable for high-speed data line protection.

The MAP5KE40CA is an ideal solution for applications that require protection against ESD or EMI. It is suitable for automotive applications, such as infotainment, body control, powertrain, and other high-dependability point of load circuits. In addition, this product is ideal for industrial and consumer applications, such as Bluetooth, WIFI, and other wireless communications.

The MAP5KE40CA is also ideal for high-speed port protection, such as digital input lines, serial ports, and I²C. It is designed to respond quickly to pulses generated by ESD transients, as well as other fast transients, providing excellent protection for the connected system.

The working principle of the MAP5KE40CA is simple. When a transient surge with higher voltage than the breakdown voltage is applied, the TVS diodes internal structure allows it to forward bias, which causes current to flow, and the voltage to be clamped to the breakdown voltage. The voltage will lower until the current reaches the peak pulse power level, or until the surge ends, whichever comes first.

The MAP5KE40CA offers excellent surge-handling capability and is ideal for protecting a variety of applications from ESD or EMI. It is a reliable, cost-effective solution that will provide superior protection for any application where transient surge protection is needed.
