Product Description
Taiwan Semiconductor SMBJ28A is a 1-element uni-directional transient voltage suppression (TVS) diode delivering 600 W peak pulse power dissipation in a compact surface-mount DO-214 package. The diode is designed to protect sensitive electronics from voltage spikes by clamping overvoltages quickly and effectively with a breakdown voltage of 31.1 V and a maximum stand-off voltage of 28 V.
Featuring a single diode configuration with a low reverse leakage current of 5 µA, SMBJ28A ensures minimal power loss during normal operation. Its clamping voltage rating of 45.4 V allows for robust transient suppression while keeping protected circuits safe under sudden surges.
This diode operates reliably within a wide temperature range from -55°C up to 150°C, making it suitable for demanding industrial, electronic manufacturing, and power management applications. The device measures 4.05 mm in length, 3.95 mm in width, and 2.45 mm in height, fitting easily into surface-mount PCB designs.
Additional features include a glass-passivated junction for enhanced durability and compliance with FBI standards. The SMBJ28A model is ideal for use in electronic circuits requiring protection from electrostatic discharge, lightning surges, and other transient voltage threats.
