SMAJ22CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection applications in portable communications, computing, and video equipment. The device features a working peak reverse voltage of 20 V, breakdown voltage range of 22.2 to 24.5 V, and is housed in a compact surface-mount SMA (DO-214AC) package. It delivers 400 watts peak pulse power dissipation at 1 ms pulse width and 1.0 watt steady-state power dissipation at 75°C lead temperature, with fast response times suitable for transient suppression. The SMAJ22CA is RoHS compliant, UL recognized, and rated for IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge protection standards, making it ideal for protecting sensitive electronic circuits from voltage transients.
