P6SMB Transient Voltage Suppressor Diode Series
Bourns P6SMB Transient Voltage Suppressor Diode Series offers 6.8V to 550V Breakdown Voltages with typical fast response times of less than 1.0 picoseconds for unidirectional devices and less than 5.0 picoseconds for bidirectional devices from 0V to Minimum Breakdown Voltage. The diodes are designed for surge and ESD protection applications in a compact chip package DO-214AA (SMB) size format.
TVS Diodes
Bourns surface mount TVS diodes are low capacitance devices that provide ESD, EFT, and surge protection for external ports of electronic devices such as cellular phones, handheld electronics and other portable electronic devices. Bourns TVS Diodes include smaller chip diodes that have the capability to provide a silicon diode with minimal packaging overhead. The chip diodes 0603, 1005, 1408, and 2010 are leadless, allowing for maximum space on PCB layouts. All Bourns diodes are RoHS compliant and meet many worldwide industry and government regulations on lead free components. TVS package diode design kits are also available from Bourns.
