SMAJ11A is a transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a compact surface mount SMA (DO-214AC) package with a standoff voltage of 11 V and maximum breakdown voltage of 12.2 V, providing fast response times of less than 1.0 ns for unidirectional operation. The device is rated for 400 watts peak pulse power dissipation with a pulse width of 1 ms, and operates reliably across a temperature range of -55°C to +150°C. SMAJ11A is lead-free and RoHS compliant, making it ideal for modern electronic designs requiring compact, high-performance transient protection in space-constrained applications.
