Overview
The SFH615A-3G is a single-channel, through-hole optocoupler manufactured by Isocom Components 2004 Ltd. It features an NPN phototransistor output and utilizes a DIP package with four pins. The device supports DC input with a maximum forward voltage of 1.65V and a maximum input current of ±50 mA. Key electrical parameters include a minimum isolation voltage of 5300 Vrms, a typical rise time of 4µs, and a typical fall time of 3µs. The current transfer ratio ranges from a minimum of 100% to a maximum of 320%. This component is designed for robust signal isolation in electronic circuits.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared technology.
- Features an NPN phototransistor output stage for reliable digital signal transmission.
- Designed for through-hole mounting in standard DIP packages for easy integration into PCB layouts.
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver applications
- Programmable current level sensing
- Computer and peripheral device interfaces
Procurement Notes
Verify the specific suffix '3G' against official Isocom documentation to confirm pinout and compliance details. Ensure the supplier provides traceability to the manufacturer's original datasheet. Confirm RoHS and UL/VDE certifications are explicitly stated for this part number variant before finalizing procurement orders.
Selection Notes
Select this component when a single-channel DC-input optocoupler with an NPN output is required. Consider the 5300 Vrms isolation rating for safety-critical applications. Evaluate the 100% to 320% CTR range to ensure compatibility with downstream logic levels. Verify that the DIP-4 package fits the available board space and assembly constraints.
Part Context
Isocom Components specializes in optical isolators and acts as a source for industry-standard replacements. The SFH615A series falls under their portfolio of plastic commercial products, which replaced earlier ceramic military lines. This specific model serves as a functional equivalent to other widely used AC/DC input optocouplers in the market.
Replacement Considerations
Cross-reference with Vishay SFH615A variants or Isocom ISP817 equivalents. Verify pin compatibility and electrical parameter overlaps such as CTR and isolation voltage before substituting.
