Product Description
The SMF3.3A is a 3.3V Transient Voltage Suppression diode in a compact surface-mount SOD-123FL package,designed to protect sensitive electronics from ESD,lightning surges, and voltage transients. With a low clamping voltage and fast response time (<1ns), it ensures robust over-voltage protection for power supplies, data lines, and communication interface in industrial, automotive, and consumer applications.
Product Features
- Peak pulse power: 200W (10/1000μs)
- Standoff voltage: 3.3V
- Fast response time
- Low clamping voltage
- RoHS compliant and halogen-free
- Compact SOD-123FL package for high-density PCB layouts
Product Applications
- Consumer Electronics (USB ports, HDMI interfaces, mobile devices)
- Automotive Systems (CAN bus, infotainment, sensors)
- Industrial Controls (PLC, communication interfaces)
- Telecommunications (network equipment, routers)
- Power Supply Protection (DC-DC converters, voltage regulators)
SMF3.3A 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.
