VO3023

Triac, SCR Output Optoisolators Overview

The VO3023 is a phototriac output optocoupler featuring a gallium arsenide infrared LED coupled to a zero-crossing triac detector. It provides electrical isolation with a rated insulation voltage of 5000 Vrms and a peak repetitive reverse voltage of 400 V for the output triac. The device is available in a 6-DIP package with a 7.62 mm pin spacing. Key electrical characteristics include a forward current of up to 50 mA and an operating temperature range from -40°C to 100°C. Trigger currents vary by suffix, such as 5 mA for the X017 variant.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix code (e.g., X001, X017) to confirm trigger current specifications and packaging type before ordering. Ensure the selected variant matches the required DIP-6 or SMD-6 form factor. Cross-reference the manufacturer datasheet revision date to confirm compliance with current regulatory standards such as UL and CQC certifications.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize noise in AC load control applications. Compare trigger current requirements against the driving circuit capabilities to ensure reliable activation. Consider the thermal management needs within the specified operating temperature range and verify that the isolation voltage meets the system's safety insulation requirements.

Triac, SCR Output Optoisolators Part Context

This part belongs to Vishay’s VO302x family of phototriac optocouplers, which includes variants like the VO3021 and VO3022. These devices share similar architectural features but differ in trigger sensitivity and package options.
