MSMBJSAC50E3/TR

TVS-Diodes

A TVS diode is a specialized type of breakdown diode that offers added robustness against impulsive voltage transient surges above normal operation. The acronym “TVS” stands for ‘Transient Voltage Suppressor’, and this type of diode is used to protect electronic circuitry from over-voltage transients such as electrostatic discharge (ESD) and lightning surges. The TVS diode is suitable for both board level and open-air circuit protection and can provide higher wattage and greater flexibility than other types of surge protection devices such as Polymeric Positive Temperature Coefficient (PPTC) or multipurpose, dual-function resettable fuses.

MSMBJSAC50E3/TR Application Field and Working Principle

The MSMBJSAC50E3/TR is a unidirectional television special application (TVS) rectifier, designed specifically for board level transient voltage protection. It features a low clamping voltage and a delay-time structure, which allows for a proper surge holding margin for ESD pulse protection. The device is intended to provide transient overvoltage protection in high-voltage environments with board-level transient voltage suppressors. Its working principle is based on the breaking down of a reverse breakdown junction and the use of an additional avalanche generated conductive path, resulting in the shunting of the voltage spikes away from the circuit.

The MSMBJSAC50E3/TR is made with a vertical structure, which provides superior protection capabilities compared to other diode technologies, such as MOVs. This device has been specially designed to provide reliable protection against overvoltage surges and ESD hits from various sources. It has been configured to provide IEC 60747-5-2 (EFT), IEC 61000-4-2 (ESD) and Telcordia 12-21 qualified transient overvoltage suppressor protection against ESD and EFT.

As with other TVS diodes, the MSMBJSAC50E3/TR can be used to protect electronic circuitry against transient voltage surges that may occur during the operation of a device. The TVS diode is designed to provide a low resistance path for any over-voltage transient and maintain a low clamping voltage throughout its operating range, eliminating the need for separate external protection components.

In addition to its use in protecting electrical circuits, the MSMBJSAC50E3/TR can also be used in automotive applications. It is designed to provide protection against voltage transients that may occur due to load dump, reverse battery and engine noise, as well as ESD pulses from wireless transmitter sources. The device helps to maintain proper levels of electrical performance while ensuring the safety and reliability of the system.

The MSMBJSAC50E3/TR TVS diode is a robust and reliable device that offers superior protection against overvoltage transients from various sources. It has been designed to provide reliable, low-cost board-level protection against common ESD and EFT transients, as well as those originating from automotive and wireless sources. The device is designed for seeking compliance with IEC 60747-5-2, IEC 61000-4-2 and Telcordia 12-21 and is ideal for both open-air and board-level protection of sensitive electronic components.
