6. Ultra-fast response speed, typically less than 1.0ps from 0V to minimum breakdown voltage
7. Molded plastic encapsulation with UL 94V-0 flame retardant grade, fully RoHS compliant
8. MSL 1 moisture sensitivity level, no pre-baking required before SMT assembly
9. Solder-plated terminals compliant with MIL-STD-750 Method 2026 soldering standard
10. Wide temperature tolerance: junction temperature -55℃ ~ +125℃, storage temperature -55℃ ~ +150℃
11. Standard tape & reel packing compatible with automatic SMT mass production lines
12. Core electrical parameters measured at 25℃ ambient temperature:
    
    
    VRWM=36V, VBR Min=40.0V / VBR Max=44.2V, IR≤1μA, VC=58.1V, IPP=6.89A

Our advantages

1. Tiny SOD-123FL footprint greatly saves PCB layout space, suitable for slim and miniaturized portable electronics
2. Low-inductance packaging avoids signal distortion, ideal for high-speed signal interface protection
3. Single bidirectional TVS replaces two unidirectional TVS diodes, simplifying BOM and PCB routing design
4. Picosecond-level ultra-fast response instantly dissipates ESD energy to prevent chip burnout
5. 400W surge handling capacity meets the protection demands of consumer, communication and low-power industrial equipment
6. MSL 1 grade eliminates complex baking processes, cutting production costs and shortening manufacturing cycles
7. Microampere leakage current reduces power consumption, perfect for battery-powered wearable devices
8. RoHS green flame retardant material complies with global electronic safety and environmental regulations
9. Stable electrical performance under high and low extreme temperature working environments
10. Standard tape & reel packaging supports all mainstream high-speed pick-and-place machines for mass manufacturing
