SMBJ18CA

ESD 抑制器/TVS 二极管 18Vr 600W 20.6A 5% BiDirectional

The SMBJ18CA SMBJ is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

SMBJ18CA Features

• 600W peak pulse power

capability at 10/1000μs

waveform, repetition rate

(duty cycles):0.01%

• Excellent clamping

capability

• Low incremental surge

resistance

• Typical IR less than 1μA

when VBR min>12V

• For surface mounted

applications to optimize

board space

• Low profile package

• Typical failure mode is a

short circuit condition for

current events exceeding

component rating

• Whisker test is conducted

based on JEDEC

JESD201A per its table 4a

and 4c

• IEC-61000-4-2 ESD

30kV(Air), 30kV (Contact)

• EFT protection of data

lines in accordance with

IEC 61000-4-4

• Built-in strain relief

• Fast response time:

typically less than 1.0ps

from 0V to BV min

• High temperature

to reflow soldering

guaranteed: 260°C/40sec

• VBR @ TJ

= VBR@25°C

x (1+αT x (TJ

- 25))

(αT:Temperature

Coefficient, typical value

is 0.1%)

• Plastic package is

flammability rated V-0 per

UL-94

• Meet MSL level1, per

J-STD-020, lead-frame

maximun peak of 260°C

• 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)

SMBJ18CA Applications
