Overview
The VO4256D-X007T is a single-channel Triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero-crossing PhotoTriac output capable of blocking up to 600 V in the off-state and conducting a maximum continuous current of 300 mA. The device provides an isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.2 V, and a peak trigger current of 1.6 mA. It is housed in a 6-SMD gull-wing package.
Feature Summary
- Non-zero-crossing triac output for precise phase control applications
- High insulation voltage rating of 5300 Vrms for robust safety isolation
- High static dV/dt immunity of 5 kV/µs to prevent false triggering
Applications
- Solid state relays (SSRs)
- Motor control circuits
- Lighting dimmer switches
Procurement Notes
Verify the specific suffix X007T corresponds to the required tape and reel packaging configuration before ordering. Confirm that the non-zero-crossing characteristic aligns with the load requirements, as this variant does not switch at the AC voltage zero crossing point. Ensure the 6-SMD gull-wing footprint matches the PCB design constraints.
Selection Notes
Select this component when phase-angle control is required rather than zero-crossing switching. The high dV/dt rating makes it suitable for noisy environments or inductive loads. Verify that the 300 mA RMS output current meets the load specifications and that the 600 V blocking voltage is sufficient for the line voltage being controlled.
Part Context
This part belongs to the VO4256 series of Triac output optocouplers from Vishay. It is distinct from zero-crossing variants like the VO4156D due to its immediate response to input signals. The device is designed for general-purpose AC power switching where timing precision relative to the AC waveform is necessary.
Replacement Considerations
Direct replacements must match the non-zero-crossing triac output and 6-SMD package. Verify equivalent isolation voltage and current ratings. Cross-reference with other Vishay VO42xx series parts or comparable industry standard triac optocouplers ensuring identical pinout and thermal characteristics.
FAQ
Does the VO4256D-X007T include a zero-crossing detection circuit?
No, this specific model is a non-zero-crossing photo triac, meaning it triggers immediately upon receiving an input signal regardless of the AC line voltage phase.
What is the maximum blocking voltage of the output triac?
The device can block up to 600 V in the off-state (VDRM).
