MP5KE7.5AE3

MP5KE7.5AE3 is a TVS - Diode of high-performance bidirectional overvoltage protection. This diode can protect against destructive impulses above 7.5A (8/20μs). Withstanding these destructive impulse is a premium feature of the diode, while the device also has the capability of protecting sensitive equipment against low overvoltage. The low leakage current of the diode is typically 0.1uA at 500V, making it suitable for a wide range of applications.

Application fields of MP5KE7.5AE3

MP5KE7.5AE3 is designed for sensitive electronic components and is an excellent choice for ultra-low capacitance bidirectional ESD protection. It is suitable for high-end automotive, medical electronics, industrial, consumer electronics, computer peripherals, home appliances, and communication modules. Its advanced characteristics also enable it to provide 5V protection in various applications. Additionally, since the device has low working voltage, it can be used in low power applications as well. The diode can be used for ESD protection of devices like microelectronic circuits, 1.8V to 5.5V functional gate circuits, 6V LED protection, 2.8V lithium-ion/polymer battery protection, high-speed data line protection, I/O protection, or power supply protection.

Working principle of MP5KE7.5AE3

TVS – Diodes are essentially an array of reverse-biased pn-junctions with low capacitance connected in parallel to form two distinct nodes. When an overvoltage surge or ESD is applied at a node, the reverse-biased pn-junctions start to conduct. This in turn causes a large but short-lived current flow, which will dissipate the overvoltage surge and protect the circuit. The most important advantage of such diodes is their very low capacitance, which helps provide quicker response times. Additionally, the leakage current of the device is very small, typically 0.1uA at 500V, which helps reduce power leakage and also extend the lifetime of the diode.

In addition to protection against overvoltage and ESD, TVS - Diode like MP5KE7.5AE3 can also monitor voltage levels and trigger on voltage warnings. This is especially useful in cases when the power supply voltage is not stable and needs to be monitored for safety reasons. Additionally, since the working voltage of the device is only 3V, it can be used in low power applications as well.

Conclusion

In conclusion, MP5KE7.5AE3 is a TVS – Diode of high-performance bidirectional overvoltage protection. It can provide up to 7.5A of protection on destructive impulses (8/20μs), while simultaneously protecting sensitive equipment against low overvoltage events. It also has the capability of monitoring voltage levels and triggering warnings should any irregularities occur. Lastly, its low working voltage makes it suitable for low power applications as well.
