TVS (Transient Voltage Suppressors) diodes are important components used to protect circuits from components like surge currents caused by lightning or other transients and electro-static discharge (ESD). The SMAJ75CAE3/TR13 is a unidirectional, 75V SMA TVS series diode. It is commonly used in applications requiring higher ESD protection than can be provided by an equivalent Silicon Avalanche Diode (SAD).

Applications

The SMAJ75CAE3/TR13 is widely used in a variety of applications. The device is typically used to protect against high voltage transients such as lightning surges, as well as ESD. Typical applications include:

• Industrial and consumer electronics applications
• Power supply and UPS equipment architectures
• External I/O circuit protection
• Cellular infrastructure equipment
• Telecom systems
• Computer systems
• Data transmission and reception systems
• Automotive electronics
• Avionics systems

Features

The SMAJ75CAE3/TR13 features an RoHS-compliant package that is suitable for both through-hole and surface-mount operations, as well as a high ESD rating of up to 24kV. It is a bidirectional device with a low clamping voltage and a low surge peak power of up to 150W per device. The device is also designed to withstand catastrophic events such as a direct lightning strike, providing added protection for circuits.

Working Principle

The SMAJ75CAE3/TR13 works by using a small amount of current to trigger an avalanche breakdown. The device’s bidirectional voltage protection feature allows it to protect both input and output circuits on the same device. When a transient voltage begins to rise above the normal operating voltage, the SMAJ75CAE3/TR13 responds by clamping the voltage to a safe level.The SMAJ75CAE3/TR13 is an excellent choice for applications requiring high ESD protection in a space-saving package. It is also capable of withstanding high transient surge voltages without fail, making it an ideal choice for lightning protection applications. With its combination of features, the SMAJ75CAE3/TR13 provides excellent circuit protection without sacrificing space or reliability.
