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

STMicroelectronics SMAJ5.0CA-TR is a 1-element, bi-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronics against voltage spikes, surges, and transient events. Housed in a compact 2-pin DO-214 surface-mount package, this diode offers 400 W peak pulse power dissipation capability, enabling it to absorb high energy transients effectively.

This TVS Diode features a minimum breakdown voltage of 6.4 V and provides a maximum reverse standoff voltage of 5 V, which ensures that normal operating voltages do not trigger the diode while adequately protecting against surges. The clamping voltage of 13.4 V limits voltage surges to safe levels, preventing damage to downstream components.

Designed to withstand harsh environmental conditions, the SMAJ5.0CA-TR operates reliably in temperatures ranging from -55°C to 150°C. It integrates a test current of 10 mA for accurate characterization and certification of protective attributes. Additionally, it offers electrostatic discharge (ESD) protection, further enhancing the reliability of electronic systems.

The package's small footprint, with dimensions of 4.6 mm length, 2.9 mm width, and 2.45 mm height, supports modern PCB design requirements and automated assembly processes. Its peak pulse current rating of 174 A allows the diode to handle large transient currents effectively. Low maximum reverse leakage current of 50 μA minimizes power consumption during normal operation.

This diode is ideal for use in industrial, telecommunications, consumer electronics, and automotive applications where transient voltage suppression is critical for device longevity and system stability.

Bi-Directional diode configuration enhances surge protection for AC and DC circuits. Single element per chip ensures focused protection without added complexity. Surface mount DO-214 package compatible with high-volume manufacturing.

Robust thermal performance supports operation across wide temperature ranges. High peak pulse power and current ratings protect against extreme transient events. ESD protection adds a secondary layer of defense against electrostatic damage.

Consistent package dimensions aid precise PCB layout and component placement. Low leakage current and reliable clamping voltage enhance circuit safety and efficiency. Compliance suitable for multiple electronic protection applications in industrial environments.
