STMicroelectronics 1-Element Bi-Directional TVS Diode Surface Mount DO-214 Package 600 W 2-Pin SMBJ Series SMBJ13CA-TR

STMicroelectronics SMBJ13CA-TR is a 1-element bi-directional transient voltage suppressor diode designed to protect sensitive electronic circuits from high voltage transient events. Housed in a compact surface mount DO-214 package, this TVS Diode supports a peak pulse power dissipation of 600 W, making it suitable for industrial, electronic, power distribution, and telecommunications applications where voltage surges may occur.

The diode features a minimum breakdown voltage of 14.4 V and a maximum reverse stand-off voltage of 13 V, delivering precise and reliable voltage clamping for overvoltage protection. Its bi-directional design allows it to clamp both positive and negative voltage transients efficiently, ensuring protection in both polarities.

With a wide operating temperature range from -55°C to 150°C, the SMBJ13CA-TR diode performs reliably in harsh and variable environmental conditions. The device offers a clamping voltage of 27.2 V and can handle surge currents up to 147 A peak pulse, suitable for handling large transient energy spikes commonly encountered in industrial and consumer electronic circuits.

The compact dimensions (length 4.6 mm, width 3.95 mm, height 2.45 mm) and the surface mount DO-214 package type facilitate dense PCB layouts and automated assembly processes. The diode exhibits low maximum reverse leakage current of 200 nA to minimize power loss during normal operation.

Applications include transient voltage suppression in power supplies, industrial controls, automotive systems, telecommunications, and data lines. The robust design enables protection against electrostatic discharge (ESD), inductive load switching, and lightning surges in a compact footprint.

Single diode configuration in bi-directional arrangement ensures dual polarity protection. Peak pulse power dissipation of 600 W withstands high surge energy. Surface mount DO-214 package supports automated assembly and space saving.

Operating temperature from -55°C to 150°C ensures reliable function in harsh environments. Low leakage current maximizes efficiency during normal device operation. Compact size optimizes PCB real estate without compromising protection.

High peak pulse current rating allows strong transient absorption. Precise breakdown and clamping voltages for effective voltage spike suppression. Suitable for industrial, electronic, power distribution, and telecom equipment.
