SMAJ8.5CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. The device features a compact DO-214AC (SMA) surface mount package with a working peak reverse voltage of 8.5 V and a breakdown voltage range of 9.44 to 10.4 V, providing fast response times of less than 5.0 picoseconds. 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 a peak forward surge current of 40 amps. The SMAJ8.5CA is RoHS compliant and conforms to JEDEC standards, making it ideal for IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection applications in compact electronic designs.
