TVS – Diodes are surge protection devices designed to protect sensitive electronics from high-voltage transients. The MASMLG110AE3 is a Transil Diode specifically designed to meet the Automotive Electronics Council’s AEC-Q101 standard, and is suitable for secondary and tertiary protection in automotive applications. This article will discuss the application field and working principle of the MASMLG110AE3.

Application Field
The MASMLG110AE3 is designed for automotive applications. It is a monolithic 18V Transil diode which uses a zener diode, a parasitic bipolar transistor and a bias resistor of 1.5kΩ. It has an operating temperature range of -55°C to +150°C, and it is suitable for use in several systems including Battery Management, Body Electronics, CAN, ECU, Crash Sensors, Safety Systems, Anti-Theft, ABS, Radio, Airbag, Lamps and more.

It is suitable for use with Automotive Ethernet, CAN FD, automotive bus-systems, LIN bus systems, and provides protection against high voltage transients such as spikes, ESD, load dump, and surge. It also provides a low clamping voltage of 4V and is rated for up to 20A peak current and 4A RMS current.

Working Principle
The MASMLG110AE3 diode operates by clamping and shunting the transient voltage away from the protected device. It uses an integrated structure composed of a Zener diode, a parasitic bipolar transistor and a bias resistor. The Zener diode performs the function of a Voltage Dependent Resistor (VDR), and its clamping voltage is determined by the resistor and the parasitic bipolar transistor. When the voltage across the diode exceeds the breakdown voltage of the Zener diode, the transistor is biased into conduction, allowing current to flow into the transient and clamping the voltage back to a safe level. This ensures the protection of the device.

The MASMLG110AE3 has a very fast response time and provides excellent protection against ESD, surge and spikes, making it ideal for automotive applications.

In summary, the MASMLG110AE3 is a Transil diode specifically designed to meet the Automotive Electronics Council’s AEC-Q101 standard. It is suitable for use with Automotive Ethernet, CAN FD, automotive bus-systems, LIN bus systems, and provides protection against ESD, surge and spikes. It has a low clamping voltage of 4V and is rated for up to 20A peak current and 4A RMS current. The MASMLG110AE3 is ideal for automotive applications due to its fast response time and excellent protection.
