VO3053

Triac, SCR Output Optoisolators Overview

The VO3053 is a non-zero crossing phototriac optocoupler featuring a GaAs infrared LED coupled to a monolithic photosensitive triac detector. It provides 5300 Vrms isolation voltage and supports a peak off-state voltage of 600 V. The device handles a maximum RMS on-state current of 75 mA with a minimum static dV/dt of 1.5 kV/µs. It operates within a temperature range of -40°C to +100°C and accepts a maximum DC forward current of 60 mA.

Triac, SCR Output Optoisolators Feature Summary

• Non-zero crossing triac output for flexible phase control applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., X007T) against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure the selected variant matches the required isolation voltage and operating temperature range for your specific design constraints before finalizing procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing switching is acceptable or required for the load type. Verify that the load current remains within the 75 mA RMS limit and that the circuit can withstand the 600 V peak off-state voltage. Confirm compatibility with the driving LED current requirements, which typically do not exceed 60 mA.

Triac, SCR Output Optoisolators Part Context

This part belongs to the VO3052/VO3053 triac driver family from Vishay Semiconductor Opto Division. These devices are designed as general-purpose optoisolators for controlling AC loads. The family utilizes a GaAs LED and a monolithic silicon triac detector to provide reliable electrical isolation between control and power circuits.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct pin-compatible replacements such as the VO3052 if zero-crossing behavior is not strictly required but different packaging is needed. Always verify that any substitute maintains the same 600 V blocking voltage and isolation ratings.
