Procurement Notes

Verify the specific suffix TU indicates tube packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the DIP-4 package dimensions match the target PCB footprint design. Check for any regional distribution restrictions or supply limitations that may affect procurement timelines. Validate that the CTR specifications meet the circuit requirements for reliable switching operation.

Selection Notes

Select this component when a single-channel transistor output optocoupler with 80 V collector-emitter voltage is required. Consider the 5000 Vrms isolation rating for applications demanding robust electrical separation. Evaluate the 18 µs switching speed against system timing constraints. Compare the 200 mW power dissipation limit with thermal management capabilities. Verify compatibility with standard DIP-4 mounting configurations during board layout.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. The series offers various Current Transfer Ratio (CTR) grades, with the 'C' suffix typically denoting a specific binning range. These devices are designed for general-purpose isolation tasks where cost-effectiveness and reliability are prioritized. The DIP-4 package allows for easy integration into through-hole assembly processes.

Replacement Considerations

Direct replacements must maintain identical pinout, isolation voltage, and package type. Verify that substitute parts offer comparable CTR ranges and switching speeds. Ensure alternative components support the same operating temperature range and voltage ratings. Cross-reference datasheets to confirm functional equivalence in the target application environment.
