Overview
The SFH615A-4XSMT&R is a single-channel optocoupler manufactured by Isocom Components. It features an NPN phototransistor output and utilizes surface mount technology in a 4-pin SDIP package. The device provides high isolation voltage of 5000 Vrms and supports a maximum collector current of 50 mA. Key electrical parameters include a typical rise time of 6 µs, a fall time of 25 µs, and a minimum current transfer ratio of 160% at 10 mA input current. The maximum forward voltage is specified at 1.65 V, with an operating temperature range spanning from -30°C to 100°C.
Feature Summary
- Provides reliable galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
- Designed for surface mount assembly to facilitate automated PCB manufacturing processes.
- Ensures signal integrity through defined current transfer ratios and switching times.
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver applications
- Programmable current level sensors
- Digital control of motors and servo machines
Procurement Notes
Verify the specific suffix 'XSMT' against official Isocom documentation to confirm surface mount configuration and pinout alignment. Ensure that the required current transfer ratio meets the target circuit design specifications, as variations may exist between standard and selected parameter versions. Confirm compliance with RoHS directives if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed requirements is needed. The NPN phototransistor output is suitable for standard logic interfacing. Consider the thermal operating limits and isolation voltage ratings relative to the system's electrical environment. Compare performance metrics such as current transfer ratio and switching times against alternative industry-standard replacements to ensure compatibility.
