Product Overview: SMAJ28A-13 TVS Diode

The SMAJ28A-13 is a robust Transient Voltage Suppressor (TVS) diode designed by Diodes Incorporated to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is specifically engineered to shield components on a circuit board from electrostatic discharge (ESD) and other harmful transient voltage spikes that can cause irreversible damage to integrated circuits and other sensitive electronics.

Key Features

• Peak Pulse Power: The SMAJ28A-13 can handle 400W of peak pulse power dissipation for a 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Breakdown Voltage: It has a standoff voltage of 28V, which provides a margin of safety for electronic components that operate at lower voltages.
• Clamping Voltage: The device features a low clamping voltage, which is crucial for protecting sensitive electronics from overvoltage conditions without compromising the system performance.
• Fast Response Time: With its fast response time to transient events, the SMAJ28A-13 quickly reacts to overvoltage conditions, minimizing the risk of damage to the protected components.
• Package: It comes in a compact SMA (DO-214AC) package, which is ideal for automated pick and place manufacturing processes and saves board space.
• Bi-directional Protection: The SMAJ28A-13 offers bi-directional protection, making it suitable for AC applications or where the polarity is undefined.

Applications

The SMAJ28A-13 TVS diode is commonly used in a variety of applications that require reliable protection against transient voltages. These include:

• Consumer electronics such as smartphones, tablets, and laptops
• Industrial control systems and automation equipment
• Telecommunication systems including base stations and networking devices
• Power supply units and voltage regulators
