SMBJ18A Description

Short technical summary and product information.

The SMBJ18A is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Goodwork Semiconductor. It offers a peak pulse power dissipation of 600 watts with a 10/1000µs waveform, making it suitable for protecting sensitive electronic components from transient overvoltage events.

This TVS diode has a breakdown voltage of 18V and a clamping voltage of 29.2V, ensuring effective suppression of voltage spikes. It operates within a wide temperature range of -65°C to +150°C and features a fast response time of typically less than 1.0 ps. The SMBJ18A is housed in a compact DO-214AA (SMB) package, designed for surface mounting applications.

Key electrical characteristics include a maximum instantaneous forward voltage of 3.5/5.0V at 50.0A for unidirectional use and a peak forward surge current of 100A for an 8.3ms single half sine-wave. The diode also has a steady-state power dissipation of 3W and thermal resistance values of 10°C/W (RθJC) and 55°C/W (RθJA).

With its robust construction, including a glass-passivated junction and pure tin plated terminals, the SMBJ18A is built for reliability. It is suitable for applications requiring protection against lightning, inductive load switching, and other transient voltage phenomena.
