Transient Voltage Suppression Diodes

Trustworthy electronic circuit protection expert

Surface Mount – 1000W > 1KSMB Series

1KSMB Series

Description

The 1KSMB series is designed specifically to protect sensitive

electronic equipment from voltage transients induced by

lightning and other transient voltage events.

Features

●Low profile package

●Ideal for automated placement

Functional Diagram

●Glass passivated chip junction

●Available in uni-directional and bi-directional

●Excellent clamping capability

●Very fast response time

●Low incremental surge resistance

●Meets MSL level 1, per J-STD-020, LF maximum peak of

260 °C

●Case: DO-214AA (SMBJ)

● 1000 W peak pulse power capability with a10/1000 us

waveform, repetitive rate (duty cycle):0.01 %

● Polarity: For uni-directional types the color band denotes

cathode end, no marking on bi-directional types

Applications

Use in sensitive electronics protection against voltage

transients induced by inductive load switching and lighting

on ICs, MOSFET, signal lines of sensor units for consumer,

computer, industrial, and telecommunication
