ISP621-2X

Transistor, Photovoltaic Output Optoisolators Overview

The ISP621-2X is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features two channels within an 8-pin DIP package, providing electrical isolation between input and output circuits. The device supports a collector-emitter voltage of 55V and offers an isolation voltage rating of 5300Vrms. Key timing parameters include a turn-on time of 4µs and a turn-off delay time of 3µs. Designed for surface mount or through-hole applications, it ensures reliable signal transmission in isolated environments.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel transistor output configuration for simultaneous signal isolation
• High isolation voltage capability ensuring robust circuit separation
• Compact 8-pin DIP packaging suitable for high-density mounting

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated power domains
• Microcontroller interface circuits with noise immunity needs

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer part number matches exactly ISP621-2X from Isocom Components 2004 LTD. Confirm the package type is 8-DIP and the output is transistor-based. Check for RoHS compliance status if required by your assembly specifications. Ensure the supplier provides original documentation to validate authenticity and performance characteristics against the official datasheet.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required in a compact form factor. The 55V collector-emitter voltage suits low-voltage logic interfacing. Consider the 4µs turn-on and 3µs turn-off times for moderate-speed digital signals. Compare with single-channel variants like ISP621-1XSM if only one channel is needed, or quad-channel versions like ISP621-4X for higher density requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP621-2X belongs to the ISP621 series of phototransistor optocouplers from Isocom Components. This series includes single, dual, and quad-channel variants such as ISP621-1XSM and ISP621-4X. All share similar isolation technologies and packaging styles, differing primarily in channel count and pin configurations. The series is designed for general-purpose isolation in commercial and industrial electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other dual-channel transistor output optocouplers in 8-DIP packages with comparable isolation voltages and timing characteristics. Verify pinout compatibility and electrical ratings before substitution. Cross-reference with Isocom's own variants like ISP621-2X-SM if surface mount is preferred.
