P4SMA 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-214AC (SMA) size format. The Transient Voltage Suppressor
series offers a choice of Breakdown Voltages from 6.8 V 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.
