Overview
The DPC817W-A-TU-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features a phototransistor output and operates with a maximum forward current of 5 mA and a forward voltage of 1.25 V. The device provides an isolation voltage of 5000 Vrms and supports a collector-emitter voltage of 35 V with a maximum collector current of 30 mA. Key electrical parameters include a current transfer ratio ranging from 80% to 160%, a collector-emitter saturation voltage of 200 mV, and rise/fall times of 18 µs. It is housed in a DIP-4 package.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical coupling.
- Utilizes a phototransistor output configuration for signal transmission.
- Designed for through-hole mounting in standard DIP-4 packages.
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics circuit protection
- Communication equipment interface isolation
Procurement Notes
Verify the specific suffix TU-V against the manufacturer's official datasheet to confirm packaging and tape-and-reel specifications. Ensure the CTR grade matches application requirements. Confirm RoHS compliance status directly with Diodes Incorporated documentation before procurement.
Selection Notes
Select this component when a single-channel phototransistor output with 5000 Vrms isolation is required. Consider the 80-160% CTR range for logic interfacing. Verify that the 35 V collector-emitter voltage and 30 mA collector current meet the load requirements of the target circuit design.
Part Context
This part belongs to the DPC817 series of transistor output optocouplers from Diodes Incorporated. The series offers industry-standard pinouts and performance levels for general-purpose isolation applications. The W variant typically denotes a specific package style within the product family.
Replacement Considerations
Check for DPC817D-A-TU or DPC817W-B-TU-V as potential substitutes with different CTR grades. Verify pin compatibility and isolation voltage ratings before substitution.
