- DescriptionThe 1N400x series is foundational to modern electronics, and this component is its highest-rated surface-mount evolution. Designed for standard-frequency power routing and robust voltage blocking, the 1N4007 SMD Diode (M7) is the go-to choice for converting AC to DC and protecting sensitive components from catastrophic high-voltage reverse spikes.Unmatched 1000V Blocking PowerWhile small signal diodes are built for speed and Schottky diodes are built for low voltage drops, the 1N4007 SMD Diode (M7) is built for brute-force protection. It boasts a Maximum Repetitive Peak Reverse Voltage (VRRM) of 1000 Volts. This immense blocking capacity makes it perfect for directly rectifying AC mains voltage or serving as a highly resilient freewheeling diode across large, high-voltage mechanical relays and industrial solenoids.Robust SMA FootprintTo bring this heavy-duty performance to modern boards, this version is housed in an industry-standard SMA (DO-214AC) surface-mount package. The flat leads provide an excellent, large solderable surface area that easily dissipates heat during continuous 1A operation while remaining robust against physical vibration. Integrating the 1N4007 SMD Diode (M7) into your workflow is simple, as the cathode is clearly identified by the printed band, ensuring perfect alignment during automated pick-and-place assembly or manual board repairs.Key FeaturesExtreme High-Voltage Rating: Safely blocks up to 1000V, making it suitable for AC mains and heavy inductive applications.High Current Handling: Safely passes up to 1.0A of continuous forward current.Modern Footprint: The SMA surface-mount package optimizes PCB real estate while maintaining through-hole reliability.Technical SpecificationsComponent Type: General Purpose Rectifier DiodeMaximum Repetitive Peak Reverse Voltage (VRRM): 1000VMaximum RMS Voltage (VRMS): 700VMaximum Average Forward Current (IF(AV)): 1.0APeak Forward Surge Current (IFSM): 30A (for 8.3ms single half sine-wave)Maximum Forward Voltage Drop (VF): 1.1V at 1.0APackage Type: SMA / DO-214AC (Surface Mount)Top Marking Code: M7Ideal ApplicationsAC to DC Rectification: Building full-wave bridge rectifiers for power supplies and AC adapters.Heavy Inductive Load Protection: Serving as a freewheeling/flyback diode across large motors, contactors, and high-voltage solenoids.Reverse Polarity Protection: Providing a robust, high-voltage barrier against backward battery or power supply insertion.Electronics Repair: Replacing blown M7 diodes in commercial power adapters, white goods, and industrial control boards.
