Product overview
The S1F is an SMD diode marking used by multiple semiconductor manufacturers, so the exact electrical specification depends on the manufacturer and full part number. One verified S1F-marked device is the Central Semiconductor CMDSH-3F, a silicon Schottky diode in an SOD-323F package. Its ratings are 30V reverse voltage and 100mA average forward current. :contentReference[oaicite:0]{index=0}
Other manufacturers also use S1F within different diode families. For example, Vishay uses S1F as the base marking for several S1FL-series rectifiers, while marking databases also show S1F associated with other 1A rectifier devices. :contentReference[oaicite:1]{index=1}
- Marking: S1F
- Component Type: SMD diode / rectifier diode
- Technology: Manufacturer-dependent; may be Schottky or standard rectifier
- Mounting: Surface Mount (SMD/SMT)
- Package: Manufacturer-dependent
- Voltage / Current Rating: Must be verified from the complete part number
Because S1F is not a unique universal part number, the marking alone should not be used to specify an exact voltage or current rating.
