The MASMCGLCE48A Transient Voltage Suppression (TVS) device from Littelfuse is a Silicon Avalanche Diode (SAD) with ultra-low capacitance, designed to protect electronics from high electrostatic discharges or very high opening/closing electromechanical pulses that die-out. This component is the solution of choice for many applications related to consumer, industrial and military.

Its rated stand-off voltage of 24V is one of its standout features. It allows designers to select the dedicated voltage needed to protect the system, without needing to define several components. The low capacitance value is another great advantage, specially for signal protection, allowing minimal signal variation to ensure the expected performance of the system. Furthermore, its low clamps voltage offers an outstanding protection capability for the system’s load, since no extra voltage is introduced to the system, minimizing energy wastage and losses.

The working principle of Littelfuse MASMCGLCE48A is based on the breakdown of reverse bipolar junction when the part voltage is exceeded. At that moment, the device is capable to sustain high surge current which is its core function.

The MASMCGLCE48A TVS is recommended for applications in which high transient voltages can appear such as during EFT tests, electronical transportation, consumer products and instrumentation. In addition, it is suitable for protection of high speed data lines from ESD, EFT and luminescence from lightning. It guaranties the protection of many automotive circuits such as radio, seats control and audio.

Not only is MASMCGLCE48A used in consumer, industrial and military applications, but it is also a reliable solution for many of the current commercial products such as hard discs, abacus, power supplies, communication device and network switches. All this products must be adequately protected from high electrostatic discharges that can damage semiconductors, especially when feature highly dense components like MEMORY ICs.

By combining all the above features, this device is the ideal solution for any application in which the variable voltage range is between 0 and 24V and the need exists to suppress transients, ESD and EFT pulses. The MASMCGLCE48A is suitable for the middle range voltage application as it offers low capacitance, low stand-off voltage and great capacitance.

To summarize, the MASMCGLCE48A Transient Voltage Suppression (TVS) device from Littelfuse is a silicon avalanche diode with ultra-low capacitance, designed to protect electronics from high electrostatic discharges or very high opening and closing electromechanical pulses. It is the ideal solution for applications requiring a middle range voltage ranging from 0 to 24V, and offers low capacitance, low stand-off voltage and great protection capability from ESD, EFT and luminescence.
