SMBJ Series RoHS - Littelfuse

1 Transient Voltage Suppression Diodes 2017 Littelfuse , are subject to change without notice. Revised: 06/07/17 Surface Mount 600W > SMBJ seriesDescriptionAgency ApprovalsThe SMBJ is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage 600W peak pulse power capability at 10/1000 s waveform, repetition rate (duty cycles) Excellent clamping capability Low incremental surge resistance Typical IR less than 1 A when VBR min>12V For surface mounted applications to optimize board space Low profile package Typical failure mode is a short circuit condition for current events exceeding component rating Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
