DPC816S-X-TR

Overview

The DPC816S-X-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SMD/SMT installation style in an SL-4 package. The device provides 5000 Vrms insulation voltage between input and output. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 30 mA, and a forward current of 5 mA. The forward voltage is 1.25 V, with a collector-emitter saturation voltage of 200 mV. The current transfer ratio ranges from 100% to 200%. Switching characteristics include a rise time of 18 µs and a fall time of 18 µs.

Feature Summary

• Provides high-voltage isolation capability for signal transmission between isolated circuits.
• Utilizes a phototransistor output configuration for digital switching applications.
• Designed for surface-mount assembly to facilitate automated PCB placement.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers requiring galvanic isolation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix 'X' against the manufacturer's latest datasheet to confirm the exact Current Transfer Ratio binning, as this character defines the CTR performance tier. Ensure the ordering code matches the required tape-and-reel quantity specifications for your production line. Cross-reference the package outline dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, single-channel solution with moderate speed (18 µs) is required. The 80 V collector-emitter voltage rating suits low-voltage logic interfacing. Compare the CTR range against load requirements to ensure sufficient drive capability. Consider thermal dissipation limits if operating near maximum current ratings. Evaluate alternative packages if higher isolation voltages or different pin configurations are needed for the specific application topology.

Part Context

This part belongs to the DPC816 series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR bins and packaging options, including tube and reel formats. The 'L' and 'S' variants typically denote slight differences in internal structure or testing criteria within the same functional family. This specific model targets cost-sensitive applications requiring reliable basic isolation without complex logic outputs.

Replacement Considerations

Direct substitutes may include other DPC816 series variants with matching CTR bins, such as DPC816L-X-TR-V or DPC816D-Y-TU-V, provided the package type (SLM-4 vs DIP-4) and CTR specifications align with design constraints. Verify pinout compatibility and insulation voltage ratings when cross-referencing with competitors like Vishay or Broadcom equivalents.
