The 1.5SMBJ14A is a transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a compact DO-214AA (SMB) package with a breakdown voltage of 15.60 V and a working peak reverse voltage of 17.20 V, delivering 1500 watts of peak pulse power dissipation at 1 ms pulse width. The device exhibits fast response times of less than 1.0 picosecond from 0 V to minimum breakdown voltage and operates across a temperature range of -55°C to +150°C. It meets IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge standards, making it ideal for protecting sensitive electronic circuits from transient overvoltage events in harsh electrical environments.
