Electro Static Discharge (ESD) is a semiconductor device used for rapid discharge of static electricity and protection of sensitive electronic components. Its core features sub nanosecond response, low capacitance, and precise clamping to prevent interfaces/chips from being damaged by human or environmental static electricity.
Features:
1. Extremely fast response:<1ns (sub nanosecond), keeping up with human static electricity (8kV-15kV,<10ns).
2. Low junction capacitance: 0.05pF -2pF, high-speed signals (USB 3.0/4.0, HDMI 2.1, RF, 5G) are not distorted.
3. Low clamp voltage: When static electricity occurs, apply voltage to 5-24V without damaging the IC.
4. Low leakage current:<0.1 μ A, suitable for battery equipment.
5. Small packaging: DFN0603, 0402, SOD-523, saving PCB space.
6. Long lifespan: Stable performance after multiple ESD impacts.
7. Compliant with standards: Meets IEC 61000-4-2 (ESD immunity) testing.
Applications：
1. Consumer electronics (the widest)
Mobile phone/tablet: USB-C, Lightning, headphone jack, SIM card, antenna, camera, touch screen.
Computer/peripherals: HDMI, DP, Ethernet, Type-A/C, SD card SATA。
Wearable: Watch TWS headphone sensor, wireless charging interface.
2. Automotive Electronics
In car: CAN/LIN/FlexRay, Ethernet USB、 Central control screen, radar.
