Datasheet - 3.0SMCJ30A

The Littelfuse 3.0SMCJ Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

3000W PPPM peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01%

For surface mounted applications in order to optimize board space

Low profile package

Typical failure mode is short from over-specified voltage or current

Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c

ESD protection of data lines in accordance with IEC 61000-4-2,30kV(Air), 30kV (Contact)

EFT protection of data lines in accordance with IEC 61000- 4-4

Built-in strain relief

Glass passivated chip junction

Fast response time: typically less than 1.0ps from 0V to BV min

Excellent clamping capability

Low incremental surge resistance
