Overview
The VOT8025AG is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an internal GaAs infrared LED optically coupled to a photosensitive zero-crossing TRIAC, housed in a 6-DIP package. Key electrical specifications include a maximum repetitive peak off-state voltage (VDRM) of 800 V and an isolation voltage rating of 5300 Vrms. The device supports a maximum continuous output current of 100 mA RMS and operates within a temperature range of -40°C to +110°C.
Feature Summary
- Integrates a GaAs infrared LED with a photosensitive zero-crossing TRIAC for precise switching control.
- Provides high-voltage isolation capability rated at 5300 Vrms between input and output circuits.
- Designed for noise-immune operation by triggering the TRIAC only when the AC line voltage is near zero.
Applications
- Solid-state relays requiring zero-crossing switching capabilities
- Motor control circuits for AC loads
- Industrial process control systems
Procurement Notes
Verify the specific suffix 'AG' against the manufacturer's latest datasheet to confirm pinout compatibility and exact electrical tolerances. Ensure the procurement source provides official documentation, as generic listings may not reflect the zero-crossing feature or specific insulation ratings required for safety compliance.
Selection Notes
Select this component when zero-crossing functionality is mandatory to minimize electromagnetic interference and inrush current. Compare the 800 V blocking voltage against the peak line voltage of the application. Confirm that the 100 mA RMS load current exceeds the maximum expected load, and verify that the 6-DIP package fits the available PCB footprint.
Part Context
This part belongs to the VOT8025A family of optocouplers from Vishay. The family typically includes variants such as VOT8025AB and VOT8025AD, which share the same core architecture but may differ in packaging options or specific mechanical dimensions. These devices are designed for general-purpose AC power switching applications where galvanic isolation is critical.
Replacement Considerations
Check for direct substitutes like the VOT8025AB or VOT8025AD if pinout and electrical parameters match exactly. Verify that any alternative zero-crossing triac optocoupler maintains the same 5300 Vrms isolation rating and 800 V blocking voltage to ensure circuit safety and performance integrity.
FAQ
Does the VOT8025AG include a zero-crossing detection circuit?
Yes, the datasheet describes the device as containing a photosensitive zero-crossing TRIAC, which ensures the output switches on only when the AC voltage is near zero.
What is the maximum isolation voltage for this component?
The VOT8025AG has a specified isolation voltage of 5300 Vrms.
