The SMAJ51CA is a bidirectional transient voltage suppressor diode engineered for surge and ESD protection applications. It features a working peak reverse voltage of 51V, a peak pulse power dissipation of 400W, and a breakdown voltage range of 56.7V to 62.7V. With a typical fast response time of less than 5.0 ns and a low reverse leakage current of 5.0 µA, this device provides robust protection. Housed in a compact DO-214AC (SMA) surface-mount package, the SMAJ51CA is ideal for safeguarding sensitive electronics in portable communications, computing, and video equipment.
