ISP321-2X

Transistor, Photovoltaic Output Optoisolators Overview

The ISP321-2X is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features two independent channels within an 8-pin DIP package, providing electrical isolation with a voltage rating of 5300Vrms. The device utilizes infrared light emitting diodes paired with NPN silicon phototransistors to transmit signals across isolated barriers. Key electrical specifications include a minimum current transfer ratio of 50% at a forward current of 5mA and a turn-off time of 3µs. The maximum off-state voltage is rated at 6V. This component is designed for reliable signal transmission in applications requiring robust galvanic isolation between input and output circuits.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'X' against official manufacturer documentation to confirm pinout configuration and packaging type. Ensure compatibility with existing board footprints for 8-DIP packages. Cross-reference datasheet parameters such as current transfer ratio and isolation voltage with system requirements before procurement. Confirm active status and availability through authorized distributors only.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required in a compact form factor. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate the 3µs turn-off time against signal speed requirements. Compare with single-channel alternatives if only one isolated path is needed to optimize cost and board space.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP321-2X belongs to the ISP321 series of high-density mounting phototransistor optically coupled isolators from Isocom Components. This series includes variants like the ISP321-4XSM, which offers four channels in a 16-pin package. The components are designed for general-purpose isolation tasks where reliability and compact size are prioritized over high-speed switching capabilities.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct substitutes within the ISP321 family or other dual-channel DIP optocouplers with matching 5300Vrms isolation and similar CTR specifications. Verify pin-to-pin compatibility and package dimensions before substitution.
