1.5SMCx SMD Transient Voltage Suppressor Diodes

Diotec Semiconductor 1.5SMCx SMD Transient Voltage Suppressor (TVS) Diodes include both uni- and bi-directional versions with a breakdown voltage range (V_BR) of 220V to 550V. These SMD transient voltage suppressor diodes feature offer a peak pulse power of 1500W (10/1000µs waveform). The 1.5SMCx SMD TVS diodes feature swift response times. These devices are built with UL 94V-0 case materials and are compliant with RoHS, REACH, and conflict minerals. The 1.5SMCx SMD transient voltage suppressor diodes are suitable for applications such as commercial-grade, ESD protection, over-voltage protection, and free-wheeling diodes.
