Littelfuse 1-Element Bi-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ28CA

Littelfuse SMAJ28CA 1-Element Bi-Directional TVS Diode, rated at 400 W peak pulse power, is designed to protect sensitive semiconductor devices from transient voltage spikes caused by lightning and other transient events. Featuring a compact 2-pin DO-214 surface mount package, this diode provides reliable, low inductance voltage clamping with a minimum breakdown voltage of 34.4 V and a maximum reverse stand-off voltage of 28 V.

This bi-directional diode configuration ensures effective surge protection in both polarities, making it suitable for a broad range of industrial and electronic applications including power supplies, telecommunication equipment, and sensitive electronic devices. The diode operates within an extended temperature range from -65°C to 150°C, offering stability under demanding operating conditions.

Key construction features include a glass passivated junction and halogen-free materials improving durability and environmental compliance. Its typical clamping voltage is 45.4 V, with a maximum peak pulse current rating of 8.8 A to handle moderate transient surges. The device also provides excellent Electrostatic Discharge (ESD) protection and exhibits a low maximum reverse leakage current of only 1 µA, contributing to energy efficiency.

The diode's fast response time, typically less than 1.0 picosecond from 0 V to breakdown voltage, ensures quick suppression of transient voltages enhancing equipment reliability. It is compatible with high temperature soldering processes (up to 250 degrees C/10 seconds), allowing seamless integration into surface mount PCB assemblies.

This Littelfuse SMAJ28CA model is part of the SMAJ series specialized for compact, high-performance transient voltage suppression. Applications span across industrial electronics, telecommunications, automotive electronic systems, manufacturing equipment, and other areas requiring robust transient voltage protection.
