Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BG' against official Isocom documentation to confirm lead form variations or tape-and-reel packaging options, as standard datasheets may list generic 'X' variants. Ensure compliance requirements such as UL recognition file E91231 are explicitly confirmed for the final assembly. Cross-reference pinout diagrams to match PCB footprint requirements before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a compact DIP-16 footprint. The four-element design reduces board space compared to discrete single-channel optocouplers. Consider the 5300 Vrms isolation rating for applications demanding high dielectric strength between input and output sides. Verify that the phototransistor output type aligns with the receiving circuit's logic levels and speed requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP847XBG belongs to the ISP817/ISP827/ISP847 series of high-density mounting phototransistor optically coupled isolators. This family is designed to replace older generation components while offering improved performance metrics. The 'X' designation typically indicates specific approval statuses or lead forms, while the base model number denotes the channel count and output type. These devices are widely used in applications requiring certified safety isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other quad-channel DIP-16 phototransistor optocouplers with comparable isolation voltages. Verify pin compatibility and current transfer ratio specifications when replacing with competitors' parts. Ensure the replacement device meets the same UL and VDE certification requirements if safety isolation is critical to the application.
