SMLJ Transient Voltage Suppressor Diode Series
General Information
Additional Information
The markets of portable communications, computing and video equipment are challenging
the semiconductor industry to develop increasingly smaller electronic components.
Click these links for more information:
Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection
applications, in compact chip package DO-214AB (SMC) size format. The Transient Voltage
Suppressor series offers a choice of Working Peak Reverse Voltage from 5 V up to 170 V
and Breakdown Voltage up to 200 V. Typical fast response times are less than 1.0 ps for
unidirectional devices and less than 5.0 ps for bidirectional devices from 0 V to Minimum
Breakdown Voltage.
