Features:
1. Extremely low junction capacitance: usually ≤ 2pF (some models ≤ 0.8pF), with almost no interference to high-frequency and high-speed signals (such as RF and Ethernet).

2. Extremely fast response speed: response time<1ns, no breakdown lag, can instantly suppress surges.

3. High insulation impedance: ≥ 100M Ω, minimal leakage current, low standby power consumption.

4. Strong flow capacity: Under 8/20 μ s waveform, the flow capacity can reach 300A~3000A.

5. Wide voltage range: DC breakdown voltage covers 140V~5000V.

6. Compact size: The minimum size can reach Φ 1.4mm × 3mm, suitable for high-density PCB layout.

7. Bidirectional symmetry, non-polar: easy to install, without distinguishing between positive and negative directions.

8. Strong environmental adaptability: working temperature of -40 ℃~+85 ℃, stable performance, long service life.

Applications：
1. Communication equipment: telephone lines RS485/232、 Surge protection for Ethernet ports, switches, and routers.

2. High frequency circuits: overvoltage protection for satellite antennas, RF receivers, and signal transmitters.

3. Consumer electronics: modems, fax machines, televisions, monitors.

4. Industry and Security: Security alarm systems, sensors, industrial control boards, relay switch spark elimination.
