BRT22H-X017

Overview

The BRT22H-X017 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a six-pin surface-mount package (SMD-6) designed for high-voltage isolation applications. The device provides an isolation voltage of 5300 Vrms between the input LED and the output triac. Key electrical parameters include a forward trigger current (IfT) of 2 mA, an off-state voltage rating of 600 V, and a hold current (IH) of 500 µA. The component is RoHS compliant and lead-free, suitable for industrial control systems requiring reliable galvanic isolation.

Feature Summary

• Provides high-voltage electrical isolation with a 5300 Vrms dielectric strength between input and output circuits.
• Features a compact six-pin surface-mount design for automated assembly and space-constrained PCB layouts.
• Utilizes a sensitive gate trigger mechanism requiring only 2 mA forward current to activate the output triac.

Applications

• Industrial motor control systems
• Solid-state relay modules
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as -X017 indicate specific packaging configurations like tape-and-reel. Confirm that the required voltage ratings and current specifications align with the target circuit design before procurement. Ensure compliance with RoHS standards if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when high isolation voltage and low trigger current are critical requirements. Compare the 600 V off-state voltage against peak line voltages in the application. Consider the SMD-6 package dimensions for footprint compatibility. Evaluate thermal management needs based on the power dissipation characteristics of the integrated LED and triac structure.

Part Context

This part belongs to the BRT22 series of Triac output optocouplers from Vishay. It shares functional similarities with models like BRT21H but differs in voltage ratings and package type. The series is designed for general-purpose AC switching applications where electrical safety and noise immunity are paramount.

Replacement Considerations

Direct substitutes may include other Vishay Triac output optocouplers with matching 600 V ratings and 5300 Vrms isolation, such as variants within the same BRT family. Verify pinout compatibility and trigger current specifications when cross-referencing with competitor devices.
