Overview
The DPC817L-D-TR-V is a single-channel transistor output optocoupler manufactured by Diodes Incorporated. It features surface mount SLM-4 packaging with 5000 Vrms isolation voltage. Key electrical parameters include a collector-emitter voltage of 35 V, collector current of 30 mA, and forward voltage of 1.25 V at 5 mA forward current. The device exhibits a current transfer ratio ranging from 50% to 600%, with rise and fall times of 18 µs each. Maximum power dissipation is 200 mW, operating within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits via an internal phototransistor structure.
- Delivers fast switching performance with specified rise and fall times for signal integrity.
- Offers wide current transfer ratio tolerance to accommodate varying gain requirements in circuit designs.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic gates
- Power supply feedback loops requiring galvanic separation
Procurement Notes
Verify the specific suffix 'D' against the required Current Transfer Ratio bin, as it defines the minimum and maximum gain limits compared to other variants like 'A'. Confirm that the SLM-4 tape and reel packaging aligns with automated assembly equipment specifications. Ensure the component status is active for long-term production needs.
Selection Notes
Select this variant when a wider CTR spread (50% to 600%) is acceptable or beneficial for specific biasing conditions. Compare against the 'A' variant if tighter gain consistency is required. Ensure the 35 V collector voltage rating exceeds the load voltage in the target application circuit.
Part Context
This component belongs to the DPC817L series of transistor output optocouplers from Diodes Incorporated. It shares the same physical footprint and basic electrical ratings as other suffixes but differs in binning classification for current transfer ratio. The series targets general-purpose isolation applications requiring compact surface mount solutions.
Replacement Considerations
Direct substitutes may include other DPC817L variants such as DPC817L-A-TR-V or DPC817L-B-TR-V, provided the CTR bin differences are accounted for. Cross-brand replacements require matching isolation voltage, package type, and electrical characteristics.
