Littelfuse SMAJ250A

The SMAJ series is designed specifcally to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

• 400W Peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycle): 0.01 %
• Excellent clamping capability
• Typical |R less than 1μΔ when VBR min>12V
• For surface mounted applications to optimize board space
• Low profle package
• Typical failure mode is short from over-specifed voltage or current
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
• IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
• ESD protection of data lines in accordance with IEC 61000-4-2
