The SMBJ‑HR Series and SMBJ-HRA Series offer customised upscreening and sorting process flows to protect from volta
ge transients induced by lightning surge and other transient voltage events. They have been screened and sorted for use in DC line protection and ESD protection in aviation electronics like FADEC, airplane sensors, avionics computers, fly-by-wire flight control systems, cockpit electronic equipment, and airport landing aid systems. Other uses include industrial applications such as the energy industry.

Both are available in compact SMB DO-214AA packages and rated for 600W of peak pulse power dissipation. Both have undergone 100% screen sorting; the SMBJ-HR has also undergone Group B (surge test, HTRB, and electrical) test sorting.

Customisable process options include visual monitor in process, single wafer lot source, high temperature storage life, X-ray inspection, reflow (2X), temperature cycle test, 3 Sigma and dynamic test, customised Vbr/lr, additional sorting, HTRB, H3TRB, good traceability, and labelling.
