SMAJ150CATR

Transient Voltage Suppressors (TVS) are used in sectors such as automotive, telecommunications and consumer electronics. In these applications, a certain level of protection is necessary to protect sensitive devices from over or under voltage transients. The SMAJ150CATR is a 1500 watt unidirectional TVS diode, with a breakdown voltage of 150 V, and a maximum clamping voltage of 315 V.

Applications

The SMAJ150CATR can be used as a protection device for other sensitive and low voltage components, as it can absorb a wide range of over voltage transients. It is often used for automotive applications such as Automotive Audio, Airbag, ABS, Vehicle Engines and Automotive Modems. It is also used in telecommunications products such as servers, routers, repeaters and switches. In consumer electronics, it is mostly used in home and Industrial Automation, peripheral devices, digital TV systems and LCD displays. It can also be used in Industrial Equipment, Drones, Robotics and Medical Devices.

Working Principle

The SMAJ150CATR TVS diode works by absorbing and clamping a wide range of over or under voltage transients. It can absorb overvoltage transients up to a certain level before its breakdown voltage is reached. Once this voltage is exceeded, the SMAJ150CATR can provide a high level of circulation current which can dissipate the energy caused by the voltage exceeding by clamping it. This voltage clamping prevents any further damage from occurring to other sensitive components. The SMAJ150CATR is a unidirectional device, meaning it only provides protection from voltage transients in one direction. Due to the device being a unidirectional device, it must be installed in the correct orientation, with the anode connected to the positive supply, and the cathode connected to the ground.

Conclusion

The SMAJ150CATR is a unidirectional 1500 watt TVS diode, most commonly used in automotive, telecommunications and consumer electronics applications. It can absorb voltage transients of up to 150 V and has a maximum clamping voltage of 315 V. It is a reliable protection device, and is useful for protecting sensitive components from over or under voltage transients.
