Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure that the selected component meets the required isolation voltage ratings for the intended circuit environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with transistor output characteristics. Consider the operating temperature range and isolation voltage requirements relative to the application's safety standards. Evaluate the current transfer ratio specifications to ensure adequate signal transmission efficiency for the load conditions.
Part Context
Isocom Components 2004 Ltd manufactures infrared optoelectronic components, including optocouplers and solid-state relays. The company has a history dating back to 1982, originally associated with Litronix and Siemens.
