Overview
The OPIA4N33DTU is a single-channel optoisolator manufactured by TT Electronics/Optek Technology. It features a Darlington transistor output with an accessible base terminal, housed in a plastic DIP-6 package. The device provides 5000 Vrms electrical isolation between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 500% at a forward current of 10mA, a collector-emitter breakdown voltage of 60V, and a maximum dark current of 100nA. It supports a continuous forward current of 50mA and operates within a temperature range of -55°C to 125°C.
Feature Summary
- High current transfer efficiency utilizing a Darlington phototransistor configuration for amplified signal output.
- Robust electrical isolation capability rated at 5000 Vrms for safe circuit separation.
- Integrated base terminal on the output transistor allows for external biasing or speed adjustment.
- Compliant with UL and VDE safety standards for industrial and commercial applications.
Applications
- Industrial control systems requiring high-gain signal isolation
- Solid-state relay driver circuits
- Microcontroller interface modules with galvanic isolation needs
Procurement Notes
Verify the specific suffix 'DTU' corresponds to the tape-and-reel packaging variant when ordering, as bulk packaging may differ. Confirm RoHS3 compliance status for environmental regulations. Ensure the selected distributor sources directly from TT Electronics/Optek Technology to guarantee authenticity. Check lead times as availability may vary based on production schedules.
Selection Notes
Select this component when high current gain is required without external amplification. The Darlington output offers superior sensitivity compared to standard phototransistor variants. Consider the base pin utility for optimizing switching speeds in high-frequency digital isolation tasks. Verify that the 5000 Vrms isolation rating meets the specific safety requirements of the target application environment.
Part Context
This part belongs to the OPIA series of high-reliability optocouplers from TT Electronics/Optek Technology. The series includes various configurations such as phototransistor and photo-Darlington outputs in DIP packages. These components are designed for demanding environments, often supporting MIL-spec screening options for aerospace and defense sectors.
Replacement Considerations
Direct replacements include the OPIA4N33 (bulk package) or generic 4N33 equivalents if isolation ratings and CTR specifications align. Verify that substitute parts maintain the 5000 Vrms isolation and 500% minimum CTR. Ensure the replacement package matches the DIP-6 footprint and pinout configuration.
