TLP626XG is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is 4PIN AC INPUT, SINGLE OPTOCOUPLE. Review the specifications below when checking this part for your BOM.
The TLP626XG is a single-channel AC input optocoupler manufactured by Isocom Components. It integrates a gallium arsenide infrared emitting diode connected in inverse parallel with a photo-transistor, enabling direct interface with AC signals without external rectification. The device provides electrical isolation with a maximum insulation voltage of 5000 Vrms and a collector-emitter breakdown voltage of 55 V minimum. It operates within a temperature range of -55°C to 100°C and features a nominal current transfer ratio of 100%.
Verify the manufacturer designation on the component marking, as the 'TLP' prefix is historically associated with Toshiba Semiconductor. Confirm that the specific 'XG' suffix corresponds to the Isocom Components variant rather than a standard Toshiba part. Ensure the datasheet explicitly lists Isocom Components as the manufacturer to validate authenticity and parameter compliance.
Select this component when an AC-coupled input interface is required for isolated digital signaling. The integrated inverse-parallel LED structure simplifies circuit design by eliminating the need for external rectifying components. Verify that the required isolation voltage and operating temperature range align with the system's environmental specifications.
This component belongs to the family of AC-input transistor-output optocouplers designed for robust industrial applications. Similar devices include the TLP626-2 and TLP626-4, which offer two and four channels respectively in DIP packages. These parts are engineered for reliable signal transmission in noisy environments where galvanic isolation is critical.
Publicly confirmed substitute part numbers for this specific Isocom variant are not available in the provided documentation.
