P4SMA Transient Voltage Suppressors

Diotec Semiconductor P4SMA Transient Voltage Suppressors feature uni- and bi-directional versions, 400W of peak pulse power dissipation, and fast response time. These diodes are compliant with RoHS, REACH, and conflict materials, and P4SMA diodes with the -AQ suffix are AEC-Q101 qualified. Diotec Semiconductor P4SMA ESD suppressors are ideally used in over-voltage protection, ESD protection, free-wheeling diodes, commercial/industrial, and automotive-grade applications.
