STMicroelectronics 1-Element Bi-Directional TVS Diode 400 W, Surface Mount DO-214 Package SMAJ130CA-TR

STMicroelectronics SMAJ130CA-TR is a high-performance 1-element bi-directional Transient Voltage Suppressor (TVS) diode engineered to provide reliable protection against voltage spikes and surges in electronic circuits. Packaged in a compact DO-214 surface mount package, this diode offers efficient transient voltage suppression with a robust peak pulse power dissipation rating of 400 W, making it suitable for demanding industrial and commercial electronic applications.

This TVS Diode features a minimum breakdown voltage of 144 V and a clamping voltage of 265 V, ensuring effective limitation of transient voltages to safe levels that protect sensitive components downstream. Its low maximum reverse leakage current of 1μA minimizes power losses when the device is in standby mode. The diode supports a maximum peak pulse current of 9 A, accommodating high transient current conditions that may arise from electrostatic discharge, lightning surges, or inductive switching.

The SMAJ130CA-TR operates reliably over a broad temperature range of -55°C to 150°C, enabling dependable performance in harsh environmental conditions commonly encountered in industrial, manufacturing, automotive, water treatment, and HVAC control systems. Its 2-pin configuration and compact physical dimensions (length 4.6 mm, width 2.9 mm, height 2.45 mm) facilitate easy integration into PCB layouts where space constraints are significant.

This component is particularly suited for applications requiring bi-directional transient voltage suppression to protect sensitive circuits from both positive and negative voltage transients. It is commonly used in electronic equipment, power supplies, telecommunication systems, and control devices to increase service life and maintain system reliability.
