Surface Mount SMA package
Standoff Voltage: 5.0 to 170 volts
Power Dissipation: 400 watts
CD214A 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-214AC (SMA)
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 ns for unidirectional devices and less than 5.0 ns 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.
