사양
This component is an opto-isolated single-channel normally open solid-state relay produced by Vishay, adopting non-contact MOS switching structure with no mechanical bounce, used for isolated signal switching and small-current circuit control.
Part Number Definition
VO1400AEF stands for the core model of optocoupler solid relay with 1 Form A single-pole normally open output. TR indicates tape-and-reel packaging suitable for automated SMT placement on production lines.
Core Electrical Parameters
It features SPST-NO single pole single throw normally open circuit structure, maximum load voltage 60V, continuous load current 100mA, maximum on-resistance 5Ω. Input side forward voltage drop is 1.1V, rated forward driving current 50mA, compatible with TTL and CMOS logic level direct driving. Input and output isolation voltage reaches 3750Vrms to achieve reinforced electrical isolation between control terminal and load circuit. Typical turn-on time 52μs and turn-off time 36μs, off-state leakage current lower than 1μA with minimal signal interference. The whole device rated power dissipation is 120mW, capable of switching both AC and DC loads steadily.
Packaging and Assembly Specifications
Standard package is 4-pin SOP surface mount type with body width 4.4mm, gull wing pin soldering mode. It belongs to MSL3 moisture sensitive device, reflow soldering needs to be completed within 168 hours after vacuum packaging opening. Factory standard reel packaging contains 2000 pieces per reel to match automatic feeding equipment.
Environmental and Compliance Standards
Operating temperature range is -40℃ to +85℃, adapting to industrial control, security equipment and precision testing instruments. The product is lead-free and meets RoHS environmental requirements, and has obtained UL, VDE and CQC safety certification. Contactless switching structure delivers long service life and strong anti-vibration and anti-shock performance compared with traditional mechanical relays.
