TVS - Diodes

TVS – Diodes are an electrical device used in various types of circuit protection applications. It stands for Transient Voltage Suppressor Diode and it works by clamping a surge voltage to a maximum level and absorbing large amount of transient energy. A TVS diode is designed to protect sensitive electronic devices from high voltage surges, and provides short circuit protection.

MSMLG48AE3 Application Field and Working Principle

The MSMLG48AE3 Transient Voltage Suppressor Diode is a unidirectional device, especially designed for protection against electrical transients such as ESD, EFT, and lightning. It provides superior ESD protection for high speed data lines with an operating voltage range from 5V to 48V. The MSMLG48AE3 offers a large clamping voltage range from 16V to 48V, and can safely absorb 10A transient energy pulse with an 8/20µs waveform.

The MSMLG48AE3 application field includes personal computers, peripherals, data transmission lines, and telecommunication lines. Its main working principle is the clamping action which, using the internal avalanche characteristic, clamps the voltage of the input signal onto the clamping voltage. This prevents the signal from surpassing the maximum level and, likewise, eliminates the risk of damage to the electronic components.

MSMLG48AE3 is able to conduct unidirectional transient current between its terminals to ground and has a stand-off voltage5Vpp in the operating range. Its maximum peak pulse power dissipation is 1.5W and its maximum peak pulse current is of 10A. Its official reverse stand-off or breakdown voltage range is from 16V to 48V. MSMLG48AE3 is distributed in a 4-pin DO27 package and is RoHS compliant.

In summary, the MSMLG48AE3 is a Transient Voltage Suppressor Diode designed for protection against ESD, EFT, and lightning, with a large clamping voltage range and the ability to safely absorb 10A transient energy pulse. It is used in various electronic applications including personal computers, peripherals, and data transmission lines. The main working principle of the MSMLG48AE3 is the ability to clamp input voltage signals and keep them within a given range, thus preventing damage to sensitive electronic components.
