STMicroelectronics 1-Element Uni-Directional TVS Diode 400W, 2-Pin DO-214 SMAJ18A-TR

STMicroelectronics SMAJ18A-TR is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode, designed for surface mount applications. It provides reliable protection for sensitive electronic devices from voltage transients and electrostatic discharges according to IEC 61000-4-2 standards.

This diode features a peak pulse power dissipation rating of 400 watts and a clamping voltage of 29.2 V, enabling it to absorb high energy surges effectively while maintaining device safety.

With a minimum breakdown voltage of 20 V and a maximum reverse stand-off voltage of 18 V, it acts swiftly to suppress transient voltage spikes. The device operates reliably across a wide temperature range from -55°C to 150°C, suitable for demanding industrial and commercial environments.

Its compact 2-pin DO-214 package facilitates easy integration into surface mounted circuit boards, delivering robust transient voltage suppression without occupying excessive board space.

The diode’s maximum peak pulse current rating of 13.7 A highlights its capability to handle significant transient currents, making it ideal for protection of power supply lines and sensitive semiconductor components.

Measuring approximately 4.6 mm in length, 2.9 mm in width, and 2.25 mm in height, it suits modern compact electronics designs.

STMicroelectronics TVS diodes are widely used in industrial, telecommunications, automotive, and consumer electronics sectors to ensure device longevity and reliability by guarding against voltage surges.
