SMAJ48CA 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 maximum reverse voltage rating of 48 V and a peak pulse power dissipation of 400 watts at 1 ms pulse width. The device offers fast response times of less than 5.0 ns from 0 V to minimum breakdown voltage, ensuring effective protection against transient overvoltages. With a steady-state power dissipation capability of 1.0 watt at 75°C and an operating temperature range of -55°C to +150°C, this suppressor diode is ideal for protecting sensitive electronic circuits in portable devices and industrial applications where reliable ESD and surge protection is critical.
