The PSMAJ400CA-13 from Diodes Incorporated is a robust Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients induced by system inductance, lightning, and electrostatic discharge (ESD). This component is a bidirectional TVS diode, meaning it can provide protection in both forward and reverse directions, making it an ideal choice for AC applications or where the polarity of the transient could be either positive or negative.

With its standoff voltage rated at 400V, the PSMAJ400CA-13 is capable of clamping and withstanding significant voltage transients while maintaining a low clamping voltage. This feature ensures the safety of the device by preventing the voltage from rising to levels that could damage the protected circuitry. The peak pulse power dissipation of this TVS diode is 400W for a 10/1000μs waveform, which allows it to absorb high transient energies without failure.

The PSMAJ400CA-13 comes in a DO-214AC package, also known as an SMA package. This package is compact and suitable for automated pick-and-place assembly processes, making it a convenient choice for high-volume production. The device also features a low incremental surge resistance and excellent clamping capability, which ensures a quick and effective response to transient events.

Diodes Incorporated has designed the PSMAJ400CA-13 to meet the IEC 61000-4-2 and IEC 61000-4-4 standards, ensuring reliability and performance under tough industry standards for ESD and electrical fast transients (EFT). These features make the PSMAJ400CA-13 an excellent choice for protecting sensitive electronics in a variety of applications, including consumer electronics, automotive systems, telecommunications, and industrial equipment.

In summary, the PSMAJ400CA-13 from Diodes Incorporated is a high-quality, versatile TVS diode that offers superior protection against voltage transients. Its robust design and compliance with international standards make it a reliable and essential component for any circuit where transient voltage protection is required.
