resistance

• Typical I

less than 1µA

R

above 12V

• For surface mounted

applications to optimize
board space

• Low prole 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

• 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

• Fast response time:

typically less than 1.0ps
from 0V to BV min

• 600W peak pulse power

capability at 10/1000μs
waveform, repetition rate

(duty cycles):0.01%

•

VBR @TJ= VBR@25°C × (1+αT

x (TJ - 25))

(αT: Temperature Coefcient)

• Glass passivated chip
junction

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

terminals

• Plastic package has

underwriters laboratory
