1.5SMC-Q 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-214AB (SMC)
size format. The Transient Voltage Suppressor series offers a choice of Breakdown Voltages from 15 V up to 68 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 their flat configuration
minimizes roll away.
