Overview
The VOT8121AG-V is a single-channel optoisolator featuring a phototriac output, manufactured by Vishay Semiconductor Opto Division. It provides an isolation voltage of 5300Vrms and supports a peak repetitive off-state voltage (VDRM) of 800V. The device operates with a maximum forward current (If) of 50mA and a typical forward voltage (Vf) of 1.2V. It handles a maximum RMS on-state current (It(RMS)) of 100mA with a minimum static dV/dt rating of 1kV/µs. Packaged in a 4-DIP configuration, it functions within a temperature range of -55°C to +110°C.
Feature Summary
- High-voltage insulation capability suitable for demanding industrial environments
- Robust noise immunity with high static dV/dt rejection
- Wide operating temperature range for extreme condition reliability
Applications
- Industrial motor control systems
- Solid-state relay interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'V' against the official Vishay datasheet to confirm package type and certification status. Ensure compatibility with existing PCB footprints for DIP-4 configurations. Cross-reference RoHS compliance requirements with project specifications before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and robust triac output are required. Compare the 5300Vrms rating against system safety standards. Evaluate the 100mA current capacity against load requirements. Consider the through-hole DIP-4 package for mechanical stability in high-vibration applications.
Part Context
This part belongs to the VOT8121 series of optocouplers designed for AC power switching applications. The series includes various packages such as SMD and DIP options. The AG-V designation specifically indicates the DIP-4 through-hole package variant with UL, cUL, and CQC certifications.
