Overview
The OPIA4N33ATR is a single-channel optoisolator manufactured by TT Electronics/Optek Technology. It features a Darlington transistor output with a base terminal for enhanced control and sensitivity. The device provides an isolation voltage of 5000Vrms, ensuring robust separation between input and output circuits. It is housed in a compact 6-SMD surface-mount package, suitable for space-constrained designs. The component is currently classified as obsolete.
Feature Summary
- Darlington output configuration with integrated base terminal
- High isolation voltage rating of 5000Vrms
- Single-channel design for signal transmission
- Surface-mount 6-SMD package format
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing between microcontrollers and high-voltage loads
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify current availability status as the part is listed as obsolete. Confirm compatibility with existing PCB footprints if substituting. Check for alternative packages or newer series replacements from the manufacturer. Ensure sourcing channels provide genuine components to avoid counterfeit risks associated with end-of-life parts.
Selection Notes
Select this component when high isolation voltage and Darlington gain are required in a small footprint. The base pin allows for adjustable sensitivity or faster switching compared to standard Darlington outputs without base access. Consider thermal management and isolation creepage distances during layout. Evaluate lifetime requirements against the obsolete status before finalizing the design.
Part Context
This device belongs to the Optek Technology optoisolator family, designed for reliable electrical isolation. It utilizes LED-to-phototransistor technology with a Darlington pair for high current transfer ratio. The 6-SMD package facilitates automated assembly. The product line emphasizes durability in noisy electrical environments.
Replacement Considerations
Check manufacturer documentation for direct pin-compatible substitutes. Verify that replacement devices maintain the 5000Vrms isolation rating and Darlington output characteristics. Ensure the alternative part supports the same 6-SMD package dimensions.
