STMicroelectronics 1-Element Bi-Directional TVS Diode 400W 2-Pin DO-214 SMAJ40CA-TR

STMicroelectronics SMAJ40CA-TR 1-Element Bi-Directional TVS Diode is designed for surface mounting in electronic protection circuits. This TVS diode features a peak pulse power dissipation capacity of 400 watts, making it ideal for transient voltage suppression in sensitive electronic components.

It provides bi-directional protection with a minimum breakdown voltage (Vbr) of 44.4 volts and a maximum reverse stand-off voltage (Vwm) of 40 volts, ensuring robust performance in surge conditions. The clamping voltage of 84 volts limits voltage spikes during transient events, protecting downstream circuitry effectively.

This diode operates reliably in a wide temperature range from -55°C up to 150°C, suitable for harsh industrial and commercial environments. Electronically, it has a test current of 1mA and a maximum peak pulse current of 27A, with an ultra-low maximum reverse leakage current of 200 nA.

The device is in the compact DO-214 package with a 2-pin configuration and measurement dimensions of 4.6 mm length, 2.95 mm width, and 2.03 mm height. Its single-element chip design ensures a simple yet effective transient voltage suppression solution.

This product finds application in protecting industrial control systems, telecommunications equipment, power supplies, automotive electronics (non-automotive standard), and other electronics exposed to transient overvoltage events. Installation on printed circuit boards is simplified due to its surface-mount mount type. The series designation is SMAJxxCA.
