The 5.0SMDJ54A is a surface-mount, unidirectional Transient Voltage Suppressor (TVS) diode engineered for surge and ESD protection in sensitive electronic circuits. This device features a working peak reverse voltage of 54V and a breakdown voltage range of 60.0V to 66.3V. It is rated for a peak pulse power dissipation of 5000W and provides a maximum clamping voltage of 87.1V at a peak pulse current of 57.5A. Housed in a DO-214AB (SMC) package, it exhibits a low reverse leakage current of 2 µA. With its fast response time, this TVS diode is well-suited for protecting power lines and I/O interfaces in applications such as portable communications, computing, and video equipment.
