Overview
The DPC1017S-TR is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features an LSOP-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 voltage of 1.25 V at 5 mA forward current, and a current transfer ratio ranging from 80% to 160%. Switching characteristics specify rise and fall times of 18 µs each. The component operates within a temperature range of -55°C to +110°C and has a power dissipation rating of 250 mW.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission.
- Features a compact LSOP-4 surface-mount package for automated assembly.
- Utilizes a phototransistor output stage for signal switching applications.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops
Procurement Notes
Verify the specific manufacturer part number against official Diodes Incorporated documentation to confirm pinout compatibility and electrical ratings. Ensure that the LSOP-4 package dimensions match the target PCB footprint. Confirm that the insulation voltage and operating temperature range meet the requirements of the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component when a single-channel isolation barrier is required with moderate speed capabilities. The 80 V collector-emitter voltage allows for versatile output interfacing. Consider the 80-160% current transfer ratio range for drive circuit design. Verify that the 18 µs switching time is sufficient for the target data rate or pulse width modulation frequency in the specific system architecture.
Part Context
This component belongs to the DPC series of transistor output optocouplers from Diodes Incorporated. The series offers various current transfer ratio grades to accommodate different sensitivity requirements while maintaining consistent packaging and basic electrical characteristics such as insulation voltage and switching speeds across the family.
Replacement Considerations
Compatible substitutes within the same family include DPC1012S-TR, DPC1013S-TR, and DPC1014S-TR. These alternatives share identical pinouts and packages but differ in current transfer ratio specifications. Verify that the CTR range of the substitute meets the minimum drive requirements of the receiving circuit.
