Diodes Incorporated SMAJ11A-13-F TVS Diode

The SMAJ11A-13-F from Diodes Incorporated is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This product is specifically engineered to safeguard voltage-sensitive components which can be compromised by these high energy phenomena.

With its SMA package, the SMAJ11A-13-F is optimized for automated assembly processes, offering a compact, surface-mount solution that is both space-saving and reliable. The device features a stand-off voltage of 11V, which is the maximum voltage that can be applied over the long term without triggering the protective mechanism of the diode. In the event of a voltage spike, the SMAJ11A-13-F can clamp and withstand significant peak pulse power – up to 400W for a 10/1000μs waveform – which is a testament to its robust design and high surge capability.

The "A" suffix in the part number indicates that this is a unidirectional TVS diode, meaning it provides protection in one direction, and is typically used in DC applications where the protection of polarity-sensitive components is essential. The SMAJ11A-13-F comes with a minimum breakdown voltage of 12.2V and a maximum clamping voltage of 18.2V at a peak pulse current of 21.9A, ensuring that it can handle substantial transient events without damage.

This TVS diode is compliant with the IEC 61000-4-2 and IEC 61000-4-5 standards, which are key industry benchmarks for electrostatic discharge (ESD) and surge immunity, respectively. Additionally, the SMAJ11A-13-F is RoHS compliant, meaning it is manufactured without the use of hazardous substances, making it an environmentally friendly choice for your circuit protection needs.

Whether you're designing power supplies, communication systems, or any other electronics that require reliable transient voltage protection, the SMAJ11A-13-F from Diodes Incorporated is an excellent choice to ensure the integrity and longevity of your product.
