TVS - Diodes

The MASMBJSAC15 is one of the most widely used TVS diodes, designed primarily for use in communication and audio-video equipment, computers, automotive and industrial applications. This TVS diode comes in an ultra-small plastic SOD-123 package and offers transient protection against voltage peaks with excellent peak pulse current capability.

Application Field

The MASMBJSAC15 is designed to protect data lines and ports from transient overvoltage events, including surge events and transients caused by load dump, ESD and lightning. The TVS diode\'s applications include EIA/TIA-232, EIA/TIA-422, EIA/TIA-485, SCSI, CAN Bus and USB lines. In addition, this TVS diode features a low capacitance of just 7.5pF and a low saturation voltage of 0.3V.

Working Principle

The MASMBJSAC15 TVS diode is a bidirectional device, intended for connection between two ports to provide bidirectional transient protection. The device is reverse biased in a circuit, and if the voltage across the diode exceeds the peak pulse power rating, the diode will turn on and divert the transient current away from the protected circuit into the ground. This will limit the voltage applied to the protected circuit and prevent damage to the protected equipment.

The MASMBJSAC15 TVS diode is a fast-acting device that can clamp transients with duration of up to 20uS and with peak pulse currents up to 2.3A. The maximum peak power of the device is 18W, which provides reliable protection against common transients. The device also offers an exceptionally fast reverse recovery time, which helps reduce overall power dissipation and improves the overall transient response.

The MASMBJSAC15 TVS diode is a fail-safe device, meaning that even if the diode fails, it will not affect the normal operation of the system. The device is also ESD and surge-protected, and has a wide operating temperature range, making it suitable for a wide range of applications.

In conclusion, the MASMBJSAC15 is an ideal TVS diode for use in a wide range of applications, due to its excellent peak pulse current rating, low capacitance and saturation voltage. The fast response time and wide operating temperature range make it suitable for use in a variety of circuits and applications.
