Overview
The SFH600-1 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductors, distributed by Isocom Components. It features an NPN phototransistor output with a nominal current transfer ratio of 63%. The device supports a maximum forward current of 60 mA and a collector-emitter breakdown voltage of 70 V. Key electrical parameters include a typical rise time of 3 µs and a fall time of 12 µs. It offers an isolation voltage of 5300 Vrms and operates within a temperature range of -55 °C to +100 °C.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
- Features high insulation capability suitable for safety-critical applications requiring robust signal separation.
- Delivers fast switching performance with defined rise and fall times for reliable digital signal transmission.
Applications
- Industrial control systems requiring isolated signal interfaces
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the manufacturer origin, as the SFH600-1 is primarily produced by Vishay Semiconductors. Confirm that the component matches the specific CTR bin (63-125%) and DIP-6 package requirements. Ensure compliance with RoHS standards and check for any obsolete status or lifecycle restrictions before finalizing procurement plans.
Selection Notes
Select this component when a single-channel phototransistor output with moderate speed and high isolation voltage is required. Consider the specific Current Transfer Ratio (CTR) range of 63-125% for circuit gain calculations. Evaluate the thermal operating range and power dissipation limits to ensure compatibility with the target application environment.
Part Context
The SFH600-1 belongs to the SFH600 series of transistor output optocouplers. This series includes variants with different CTR ranges, such as the SFH600-2 and SFH600-3. These components are designed for general-purpose isolation in compact DIP-6 packages, offering a balance of performance and reliability for various electronic designs.
Replacement Considerations
Public confirmed substitute part numbers include SFH600-2 and SFH600-3 from the same manufacturer series. Verify that the replacement variant's CTR range and timing characteristics meet the original design specifications.
