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.

TVS Diodes, ESD, & Load Dump Protectors

Diotec Semiconductors TVS Diodes, ESD, and Load Dump Protectors cover almost every need of transient voltage protection. This comprehensive portfolio contains ESD protection arrays in tiny leadless packages to industry standard TVS diodes with a wide working voltage range and powerful automotive load dump protectors. These uni- or bidirectional components offer wide operating voltage ranges and low junction capacitances. Applications include consumer, industrial, automotive, and telecom.
