SMBJ54CA 54V Bidirectional TVS Diode – SMB (DO-214AA)

Product Description:
The SMBJ54CA TVS Diode is a bidirectional transient voltage suppressor specifically engineered to protect sensitive 54V electronic circuits from high-energy surges. With a reverse stand-off voltage of 54V, a breakdown voltage up to 66.3V, and a clamping voltage of 87.1V, it ensures stable and efficient suppression of transient spikes caused by lightning, inductive switching, and electrical disturbances.

Built in a compact SMB (DO-214AA) package, this diode provides excellent clamping performance, extremely fast response time (<1 ps), and high pulse capability with 6.9A peak current. It supports high-temperature soldering up to 260°C, making it reliable for automated PCB assembly in industrial, automotive, and communication systems.

With low leakage, strong durability, and robust surge absorption, the SMBJ54CA is ideal for protecting ICs, MOSFETs, power lines, sensors, and other sensitive circuits.
