TVS - Diodes

TVS - Diodes are an important part of many electronic components and devices. A TVS Diode (also known as a Transient Voltage Suppressor Diode) is a device that provides protection against surges in electrical circuit. It is used to protect circuits against transient voltage, which can occur due to power line disturbances or electrostatic discharge. The TVS Diode is similar to a Zener Diode, but has enhanced characteristics that make it more suitable for protecting sensitive electronic equipment.

MSMBJ78AE3 Application Field and Working Principle

The MSMBJ78AE3 is a TVS Diode manufactured by Fairchild Semiconductor. This device is designed for use in automotive and industrial applications and is suitable for use as a Transient Voltage Suppressor (TVS) Diode. It is designed to protect circuits against the harmful and destructive effects of transient voltages that can occur due to power line disturbances or electrostatic discharge.

The MSMBJ78AE3 is a reverse-biased TVS device, and it provides clamping protection for over-voltage transients. It is capable of handling transient voltages up to 78V with a standoff voltage at 6.8V, meaning it will remain off until the voltage exceeds 6.8V in either direction. The device has a fast response time, allowing it to quickly react to any over-voltage transient.

The MSMBJ78AE3 is also designed to meet the requirements of AEC-Q101 for transient voltage suppression applications. This type of device is capable of handling transient voltages up to 78V, with a clamp voltage of 6.8V and a hold current of 15A. It has an operating temperature range of -55°C to +150°C and is available in an SOD-123 package.

The MSMBJ78AE3 is an important device for providing protection against surges that can occur in any type of electrical circuit. Its enhanced characteristics make it suitable for a wide range of applications, from automotive and industrial to consumer electronics and communications.

Conclusion

The TVS Diode, such as the MSMBJ78AE3, is an essential device for providing protection against electrical circuit surges. It is designed for use in a wide range of applications, including automotive, industrial, consumer electronics and communications. Its fast response time, high breakdown voltage and standoff voltage make it a perfect solution for protecting sensitive electronic equipment from damaging transient voltages.
