SMAJ120CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a compact SMA (DO-214AC) surface mount package with a breakdown voltage of 133 V maximum and a working peak reverse voltage of 149 V, providing reliable protection across a wide voltage range. The device delivers 400 watts peak pulse power dissipation with a response time of less than 5.0 nanoseconds, ensuring fast transient suppression. Operating over a temperature range of -55°C to +150°C, the SMAJ120CA is ideal for protecting sensitive circuits in consumer electronics and industrial applications requiring robust ESD and surge protection.
