SMAJ200A 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 200V with a breakdown voltage range of 204V to 247V, housed in a compact DO-214AC (SMA) surface mount package. The device delivers 400 watts peak pulse power dissipation at 1 ms pulse width and 1.0 watts steady-state power dissipation at 75°C lead temperature, with a fast response time of less than 1.0 picosecond. Operating across a temperature range of -55°C to +150°C, the SMAJ200A is ideal for protecting sensitive electronics against transient overvoltage events per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards, offering reliable protection in demanding applications.
