STMicroelectronics 1-Element Bi-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ5.0CA-TR

STMicroelectronics SMAJ5.0CA-TR is a 1-element bi-directional transient voltage suppression (TVS) diode engineered to protect electronic circuits against voltage spikes and transient surges. This diode offers a reliable and efficient means of clamping voltage transients to safe levels, thereby safeguarding sensitive semiconductor components from damage and improving system integrity.

The device features a single diode configuration in a compact 2-pin DO-214 surface mount package measuring 4.6 mm in length, 2.9 mm in width, and 2.45 mm in height. It is designed for high peak pulse power dissipation of 400 W, making it suitable for robust industrial, automotive (non-certified), telecommunications, and power supply applications requiring protection from transient voltage spikes.

Electrical characteristics include a minimum breakdown voltage (Vbr) of 6.4 V, maximum reverse stand-off voltage (Vwm) of 5 V, and a clamping voltage (Vc) at 13.4 V. The maximum peak pulse current (Ippm) of 174 A supports the absorption of substantial transient events, while the low maximum reverse leakage current of 50 μA minimizes power loss during normal operation. The diode supports an operating temperature range from -55°C to 150°C, enabling use in harsh environments and industrial temperature conditions.

The SMAJ5.0CA-TR does not carry automotive standard approvals but incorporates ESD protection to improve circuit robustness. It is ideal for transient voltage suppression in manufacturing, electronic assembly, power management systems, and commercial electronics, protecting circuits from inductive load switching, lightning, and electrostatic discharge.

This product is supplied in reel packaging for automated PCB assembly processes, enabling efficient production workflows. The reliable surface mount design reduces assembly time and ensures consistent electrical performance, suitable for modern electronics manufacturing.
