STMicroelectronics 1-Element Uni-Directional Transil TVS Diode 600 W, 2-Pin DO-214AA SMBJ22A-TR

The STMicroelectronics SMBJ22A-TR is a single-element uni-directional Transil transient voltage suppressor (TVS) diode designed to protect electronic circuits against high voltage transients and surges. Rated at 600 W peak pulse power dissipation, this device is housed in a compact DO-214AA (SMB) surface mount package, making it ideal for circuit board applications needing efficient ESD and surge protection.

This diode features a minimum breakdown voltage of 24.4 V and a maximum reverse stand-off voltage of 22 V, providing robust transient voltage suppression with a clamping voltage of 48.3 V. It delivers a maximum peak pulse current of 83 A, ensuring reliable protection against voltage spikes. Operating over a wide temperature range from -55°C up to 150°C, it is suitable for various industrial, electronic component, and power management applications.

Physical dimensions of the diode are 4.6 mm in length, 3.95 mm in width, and 2.45 mm in height, making it a space-efficient solution for printed circuit board mounting. With a standard 2-pin configuration and a single diode element per chip, it offers a simple and effective surge protection method.

The SMBJ22A-TR does not feature automotive standard certification, targeting primarily industrial, consumer electronics, and power supply applications requiring surface mount transient voltage suppression. Its robust packaging ensures durability under mechanical stresses during reflow soldering and assembly processes.

This transient voltage suppressor is widely used in industrial electronics, power supplies, telecommunication equipment, and consumer electronic devices to safeguard against voltage transients resulting from inductive load switching, lightning, and other electrical disturbances.
