Overview
The DPC816S-B-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SMD/SMT mounting style in an SL-4 package. The device provides 5000 Vrms insulation voltage and utilizes a phototransistor output. Key electrical parameters include a forward current of 5 mA, a forward voltage of 1.25 V, and a collector-emitter saturation voltage of 200 mV. The maximum collector-emitter voltage is 35 V with a maximum collector current of 30 mA. The current transfer ratio ranges from 130% to 260% at 5 mA input.
Feature Summary
- Provides high-voltage isolation between input and output circuits via optical coupling.
- Utilizes a phototransistor output for digital signal transmission.
- Designed for surface-mount assembly in compact SL-4 packages.
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor-based circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix B indicates the 130-260% CTR bin. Confirm the SL-4 package dimensions match the PCB footprint. Ensure the 35 V collector-emitter rating meets the circuit requirements. Check RoHS compliance status for environmental regulations. Validate supplier authenticity through authorized channels.
Selection Notes
Select this component when 35 V output voltage capability is sufficient. Compare against DPC816L-B-TR if higher voltage ratings are needed. Consider the SL-4 package size constraints during layout. Evaluate the 130-260% CTR range for logic level compatibility. Verify thermal dissipation limits within the enclosure.
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. The DPC816S variant specifically denotes the SL-4 package form factor. Other variants include DIP packages or different voltage ratings.
Replacement Considerations
DPC816L-B-TR offers similar functionality but with higher voltage ratings. DPC817S-B-TR-V is a related variant with different voltage specifications. Verify pinout compatibility before substitution. Check CTR bin differences for circuit performance impact.
