Overview
The DPC817L-B-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an SLM-4 surface-mount package with a 5000 Vrms isolation voltage. The device operates with a forward current of 5 mA and a forward voltage of 1.25 V. Key electrical parameters include a collector-emitter voltage of 35 V, a maximum collector current of 30 mA, and a collector-emitter saturation voltage of 200 mV. The current transfer ratio ranges from 130% to 260% at the specified forward current.
Feature Summary
- Provides galvanic isolation between input and output circuits via an internal phototransistor.
- Designed for surface-mount assembly in compact SLM-4 packages.
- Supports high isolation voltage ratings for safety-critical signal transmission.
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix TR-V against official Diodes Incorporated documentation to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure the ordering part number matches the required CTR binning (B grade) as defined in the manufacturer's datasheet before finalizing procurement orders.
Selection Notes
Select this component when a single-channel transistor output isolator with moderate current transfer ratio is required. Compare the 130-260% CTR range against application requirements. Verify that the 30 mA collector current limit and 35 V collector-emitter voltage are sufficient for the target load conditions.
Part Context
This component belongs to the DPC817L series of transistor output optocouplers from Diodes Incorporated. The series offers various CTR grades (A, B, C, D) to accommodate different gain requirements while maintaining consistent physical dimensions and electrical characteristics such as isolation voltage and switching speeds.
Replacement Considerations
Check Diodes Incorporated documentation for direct substitutes within the DPC817L family, such as DPC817L-A-TR-V or DPC817L-C-TR-V, which share identical pinouts but differ in current transfer ratio specifications.
