Littelfuse Uni-Directional TVS Diode 3 kW 2-Pin DO-214 SMDJ28A

The Littelfuse SMDJ28A is a uni-directional transient voltage suppression (TVS) diode engineered for safeguarding sensitive electronic equipment from sudden voltage spikes, including those caused by lightning and other transient events. Designed with a high peak pulse power dissipation of 3 kW, this diode reliably absorbs surges and prevents damage to circuit components.

Its DO-214 surface-mount package provides a compact low-profile form factor, making it suitable for printed circuit boards where space optimization is essential. The device excels in applications requiring advanced protection, such as industrial controls, telecommunications, medical devices, and consumer electronics.

The SMDJ28A features a minimum breakdown voltage of 31.1 V, a clamping voltage of 45.4 V, and a maximum reverse stand-off voltage of 28 V. With a maximum peak pulse current rating of 66.1 A, it effectively manages sizable surge currents. The diode's fast response time - typically less than 1.0 ps - from 0 V to breakdown voltage ensures rapid action against transient threats.

Durability is enhanced by its glass passivated chip junction and built-in strain relief, while high-temperature soldering up to 260°C/40 seconds at terminals contributes to the reliability of assembly processes. Its low incremental surge resistance, ESD protection, and excellent clamping capability further support long-term stable operation.

The surface-mount configuration streamlines integration into modern electronic assemblies, and its wide operating temperature range from -65°C to 150°C makes it suitable for demanding environments. With a pin count of 2 and single element configuration, the SMDJ28A is straightforward for designers to specify and deploy.

Common use cases for this TVS diode include industrial and laboratory equipment, telecommunication boards, automated control systems, and other electronic applications requiring robust transient protection. The SMDJ28A helps maintain equipment uptime, reduces risk of costly repairs, and supports high-reliability manufacturing requirements.
