1.5SMC-Q Transient Voltage Suppressor Diode Series
General Information
Additional Information
Manufacturers 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 6.8 V up to 130 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.
