Description

The 1.5SMC series is designed specically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features

• For surface mounted

applications to optimize board space

• Low prole package.

• Typical failure mode is short from over-specied voltage or current

• Whisker test is conducted

based on JEDEC JESD201A per its table 4a and 4c

• IEC-61000-4-2 ESD

15kV(Air), 8kV (Contact)

• ESD protection of data

lines in accordance with IEC 61000-4-2 (IEC801-2)

• EFT protection of data

lines in accordance with IEC 61000-4-4 (IEC801-4)

• Built-in strain relief

•

VBR @TJ= VBR@25°C × (1+αT

x (TJ - 25))

(αT: Temperature Coefcient)

• Glass passivated chip

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

• Excellent clamping capability

• Low incremental surge

resistance

• Typical I

less than 1µA

above 13V

• High temperature soldering guaranteed: 260°C/40 seconds at

terminals

• Plastic package has underwriters laboratory ammability 94V-O

• Meet MSL level1, per

J-STD-020, LF maximum peak of 260°C
