The SMAJ26A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a working peak reverse voltage of 26 V, breakdown voltage range of 28.9 to 31.4 V, and a peak pulse power dissipation of 400 watts at 1 ms pulse width. The device is housed in a compact DO-214AC (SMA) surface mount package with a maximum clamping voltage of 42.1 V and peak maximum current of 9.5 A at 10/1000 µs pulse width. Operating over a temperature range of -55°C to +150°C, the SMAJ26A provides fast response times and is ideal for protecting sensitive circuits against transient overvoltage events in accordance with IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge standards.
