TVS - Diodes

A Transient Voltage Suppressor (TVS) diode, also known as a suppressor diode, is a semiconductor device that comes in a variety of structures and is designed to protect against lightning, electrical transients and surges. TVS diodes are used in applications such as electrical performance testing, power systems analysis, power supply noise abatement, and voltage suppression from data lines. This article will discuss the working principle and application field of MASMBJSAC50E3 TVS diode.

MASMBJSAC50E3 Application Field

The MASMBJSAC50E3 is a motor speed sensor TVS diode, which is designed to be used in applications such as motor speed control and motor protection. This diode can protect motors with operating voltages up to specifically 200V by suppressing voltage transients and surges. This diode can also be connected to a variety of motor control circuits and can be used as part of the overall motor protection system. It\'s an ideal choice for protecting against over-voltage and reverse-voltage problems in motors. The MASMBJSAC50E3 can also be used for a wide range of electric motors, including brushless DC (BLDC) motors, stepper motors, servo motors, and permanent magnet DC (PMDC) motors.

MASMBJSAC50E3 Working Principle

The MASMBJSAC50E3 is a bi-directional, unidirectional, and fast-recovery diode. It is able to protect circuits and systems from surges brought about by electrical transients and lightning. It is also able to safeguard against incorrect polarity, overvoltages, and reverse voltages in systems. This is accomplished by the integrated Zener diode, which is normally forward biased, and the integrated metal-oxide varistor (MOV).

The Zener diode clamps any high voltages during a surge, while the MOV shunts further power away from the system if the Zener diode is unable to control the surge. The MOV absorbs the power, limiting the surge to a safe amount. This combination of Zener diodes and MOVs is known as “Transient Voltage Suppression” or “TVS” for short.

Conclusion

The MASMBJSAC50E3 TVS diode is designed to protect motors with operating voltages of up to 200V. This diode can protect against surges brought about by electrical transients and lightning, as well as protecting against incorrect polarity, overvoltage, and reverse voltage in systems. It has an integrated Zener diode, which clamps any high voltages, and an integrated metal-oxide varistor which shunts power away from the system if the Zener diode can’t control the surge.
