Overview
The DPC816L-B-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface-mount package and provides 5000 Vrms insulation voltage. The device utilizes a phototransistor output with a collector-emitter voltage rating of 80 V and a maximum collector current of 30 mA. 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 current transfer ratio ranges from 130% to 260%, with rise and fall times of 18 µs.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical coupling.
- Features a compact SLM-4 surface-mount package for automated assembly.
- Delivers high insulation voltage capability for safety-critical applications.
Applications
- Signal isolation in industrial control systems
- Interface between microcontrollers and power stages
- Noise immunity enhancement in communication lines
Procurement Notes
Verify the specific suffix B against the manufacturer's datasheet to confirm the current transfer ratio binning. Ensure the SLM-4 footprint matches the design layout. Confirm RoHS compliance status through official documentation before integration into regulated products.
Selection Notes
Select this component when a low-power, single-channel isolation solution is required with moderate speed characteristics. The 80 V collector-emitter voltage suits low-voltage logic interfacing. Compare CTR specifications against other variants like A or Y if tighter gain tolerances are needed.
Part Context
This part belongs to the DPC816L series of transistor output optocouplers. Variants within this family differ primarily in current transfer ratio bins (A, B, X, Y) while sharing identical pinouts, packages, and basic electrical ratings such as isolation voltage and switching speeds.
Replacement Considerations
Direct substitutes include DPC816L-A-TR-V, DPC816L-X-TR-V, and DPC816L-Y-TR-V. These share the same package and electrical limits but offer different current transfer ratio ranges. Verify CTR requirements before substitution.
