and automotive grade AEC

Q101 qualified

• Surface mount component

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

• IEC-61000-4-2 ESD

30kV(Air), 30kV (Contact)

• 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

• Glass passivated chip

junction

• 600W peak pulse power

capability at 10/1000μs

waveform, repetition rate

(duty cycles):0.01%

• Fast response time:

typically less than 1.0ns

from 0V to V

• Excellent clamping

capability

• Low incremental surge

resistance

• Typical I

V

• UL Recognized compound

meeting flammability

rating V-0

• Meet MSL level1,

per J-STD-020, High

temperature soldering

guaranteed: 260°C/10

seconds at terminals

• Matte tin lead–free plated

• Halogen free and RoHS

compliant

• Pb-free E3 means 2nd

level interconnect is Pb-

free and the terminal finish

material is tin(Sn) (IPC/

JEDEC J-STD-609A.01)

Notes:

1. Non-repetitive current pulse, per Fig.4 and derated above T

2. Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal.

3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional

component only,duty cycle=4 per minute maximum.

4. VF < 3.5V for part number below 300A, VF < 5.0V for part number with 300A or above.
