## Description

The SMBJ26CA from Multicomp Pro is a high-reliability bidirectional transient voltage suppressor (TVS) diode engineered to safeguard sensitive microelectronics and power buses from overvoltage transients, electrostatic discharge (ESD), and lightning-induced surges. Operating with a reverse standoff voltage ($V_{RWM}$) of 26V and a minimum breakdown voltage ($V_{BR}$) of 28.9V (reaching a maximum of 31.9V at 1mA test current), this device delivers a robust clamping voltage ($V_C$) up to 42.1V at a peak pulse current of 14.3A. Designed for high-density surface mount architectures, it houses a glass-passivated junction capable of absorbing a peak pulse power dissipation of 600W using a standard 10/1000µs waveform.

Housed in a low-profile DO-214AA (SMB) molded plastic package with a UL 94V-0 flammability rating, the component supports efficient thermal and mechanical performance across a wide operating junction temperature range of -55°C to +150°C. Its fast response time—typically under 1.0 picosecond from 0V to $V_{BR}$ min—ensures immediate suppression of fast-rising voltage spikes. The bidirectional topology provides symmetrical protection for alternating or AC signals, making it well-suited for safeguarding telecommunication interfaces, DC power distribution rails, industrial automation nodes, and computer peripheral I/O ports against severe electrical overstress events.
