Description The 1.
5SMB Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Features & Benefits ■ For surface mounted applications to optimize board space ■ Low profile package ■ Typical failure mode is short from over-specified voltage or current ■ VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25))(αT:Temperature Coefficient, typical value is 0.
1%) ■ Excellent clamping capability ■ Low incremental surge resistance ■ Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c ■ ESD protection of data lines in accordance with IEC 61000-42, 30kV(Air), 30kV (Contact) ■ EFT protection of data lines in accordance with IEC 610004-4 ■ Built-in strain relief ■ Glass passivated chip junction ■ 1500W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.
01% ■ Meet MSL level 1 per J-STD-020, and...
