SMBJ Transient Voltage Suppressor Diode Series
General Information
The markets of portable communications, computing and video equipment are challenging
the semiconductor industry to develop
increasingly smaller electronic components.
Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection
applications, in compact chip package DO-214AA (SMB) size format. The Transient Voltage
Suppressor series offers a choice of Working Peak Reverse Voltage from 5 V up to 495
V and Breakdown Voltage up to 550 V. Typical fast response times are less than 1.0
picosecond for unidirectional devices and less than 5.0 picoseconds for bidirectional devices
from 0 V to Minimum Breakdown Voltage.
Bourns® Chip Diodes conform to JEDEC standards, are easy to handle with standard pick
and place equipment and the flat configuration minimizes roll away.
