Features:
1. Compact size: Standard packaging (0402/0603/0805/1206, etc.), suitable for high-density PCBs.
2. Fast response: nanosecond (ns) level conductivity, sensitive protection.
3. Non polarity: bidirectional protection, easy to weld.
4. Small parasitic inductance: good suppression of high-frequency interference.
Applications：
1. Consumer Electronics and Interface Protection
Interface protection: ESD electrostatic protection for USB, HDMI, RJ45, audio port, and SIM card slot.
Onboard power supply: DC-DC power input terminals for mobile phones, computers, and set-top boxes to suppress surges.
Button/touch screen: prevent human static electricity or switch spikes from damaging the driver IC.
2. Automotive Electronics
In car circuit: load drop and surge protection for ECU, BCM, sensors, headlights, and wiper control.
New energy vehicles: BMS (Battery Management System), OBC (On Board Charger), EV charging station.
3. Industry and Communication
Industrial control: I/O ports and power surge suppression for PLCs, frequency converters, and instruments.
5G/Communication: Signal and power lightning protection for base stations, optical switches, and switches.
Relay/solenoid valve: Absorbs the reverse induced electromotive force generated when the coil is de energized.
4. New energy and household appliances
Photovoltaic/wind power: lightning surge protection for inverters and combiner boxes.
Smart home appliances: control boards and motor drive protection for air conditioners, refrigerators, and washing machines.
