Overview
The SFH618A-4X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductors. It features an NPN phototransistor output and utilizes a PDIP-4 through-hole package. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The device offers a high insulation voltage of 5300 Vrms and a current transfer ratio ranging from 160% to 320%. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage isolation with a rated insulation voltage of 5300 Vrms for safety compliance.
- Features a single-channel configuration with an NPN phototransistor output stage.
- Delivers a wide current transfer ratio range to accommodate varying signal transmission requirements.
Applications
- Industrial control systems requiring galvanic isolation
- Signal switching in low-power electronic circuits
- General-purpose isolation interfaces
Procurement Notes
Verify the specific suffix designation to ensure the correct Current Transfer Ratio (CTR) bin is selected, as variants exist within the SFH618A series. Confirm that the PDIP-4 through-hole package aligns with the target PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status or recommended soldering profiles prior to finalizing procurement orders.
Selection Notes
Select this component when a robust isolation barrier exceeding 5000 Vrms is required alongside moderate speed performance. The 100 mA collector current capability supports direct driving of certain loads without additional amplification. Ensure the forward current does not exceed 60 mA to maintain optimal CTR and thermal stability within the specified operating temperature range.
Part Context
This part belongs to the SFH618A family of transistor output optocouplers designed for general-purpose isolation applications. The series is characterized by its reliability and compliance with international safety standards. The specific model distinguishes itself through its defined CTR range and packaging style, serving as a standard solution for basic signal isolation tasks in consumer and industrial electronics.
Replacement Considerations
The VO618A-4X016 is a documented substitute within the same product family, offering similar functionality but with different electrical ratings such as an 80 V collector-emitter voltage and 50 mA collector current. Verify pinout compatibility and thermal characteristics before substitution.
