- Industrial Controls (PLC, communication interfaces)
- Telecommunications (network equipment, routers)
- Power Supply Protection (DC-DC converters, voltage regulators)
SMF12A Datasheet
How It Works?
When a voltage surge exceeds the diode's breakdown voltage, the device rapidly conducts, diverting excess current away from sensitive components. Once the transient event ends, it returns to a high-impedance state, allowing normal circuit operation.
