The SMBJ HR Series High-Reliability TVS Diode is an "off-the-shelf" upscreened High-Reliability TVS Diode from Littelfuse. It is available in a compact DO-214AA SMB package and is rated for 600W of peak pulse power dissipation. These components, which protect sensitive electronic equipment from voltage transients induced by lightning surge and other transient voltage events, have been specially screened and sorted for use in DC line protection in aviation electronics and other applications that demand high reliability. The SMBJ-HR Series has undergone both a 100% screen sorting process and a Group B (surge test, HTRB, and electrical) test sorting process. Littelfuse High-Reliability Transient Voltage Suppression (TVS) Diodes are also available with customized upscreening and sorting process flows.
