ISP621-4XBL

Transistor, Photovoltaic Output Optoisolators Overview

The ISP621-4XBL is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features four independent channels within a single DIP-16 plastic package, providing electrical isolation between input and output circuits. The device utilizes an infrared LED emitter paired with NPN phototransistor receivers to transmit digital signals across the isolation barrier. Key electrical specifications include a maximum forward current of 50 mA, a collector-emitter breakdown voltage of 35 V, and a minimum isolation voltage rating of 5300 Vrms. The unit operates within a temperature range of -55°C to 100°C and complies with UL and VDE safety standards for industrial applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BL' against official Isocom documentation to confirm lead frame material and plating specifications. Ensure the DIP-16 package dimensions match your PCB footprint requirements. Confirm that the 5300 Vrms isolation rating meets your system's safety clearance needs. Check for RoHS compliance status if required by your manufacturing regulations. Validate operating temperature ranges against your environmental conditions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a confined space. The four-channel design reduces assembly complexity compared to using discrete single-channel optocouplers. Consider the 50 mA forward current limit for driver circuit design. Ensure the 35 V collector-emitter voltage is sufficient for the load side application. Verify that the DIP-16 package is compatible with your automated placement equipment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP621 series of phototransistor optocouplers from Isocom Components. The series offers various channel counts and packaging options to suit different density requirements. The ISP621-4XBL specifically provides a quad-channel solution in a standard dual-in-line package. It serves as an alternative to legacy components in industrial and commercial electronics where reliable signal transmission across isolation barriers is critical.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include other quad-channel DIP-16 optocouplers with similar isolation ratings and pin configurations.
