ILQ30

Transistor, Photovoltaic Output Optoisolators Overview

The ILQ30 is a quad-channel photodarlington output optocoupler manufactured by Vishay Semiconductor Opto Division. It features four independent channels within a single 16-pin DIP package, providing high isolation voltage of 5300 Vrms. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1.5 V. It offers a minimum current transfer ratio of 100% and handles up to 125 mA collector current at 30 V collector-emitter voltage. Power dissipation is rated at 250 mW, operating reliably between -55°C and +100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Quad-channel configuration for multi-signal isolation in a compact footprint
• High isolation voltage capability for robust circuit protection
• Photodarlington output structure ensures high current gain and sensitivity

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation control systems requiring multiple isolated signals
• Power supply feedback loops with galvanic isolation needs
• Data communication interfaces demanding signal integrity across noise barriers

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code if ordering variants, as standard ILQ30 denotes the base quad-channel part. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to procurement. Check for End-of-Life (EOL) notifications from Vishay, as availability may be restricted. Ensure packaging type matches production requirements, typically tubes for this component. Validate pinout compatibility with existing PCB layouts before finalizing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the ILQ30 when multiple isolated channels are required without increasing board space. Its photodarlington output provides higher current drive capability compared to standard transistor outputs. Consider the 5300 Vrms isolation rating for applications involving high-voltage separation. Evaluate the 10 µs rise time against system speed requirements. Ensure thermal management accommodates the 250 mW power dissipation in enclosed environments.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILQ30 belongs to Vishay's broader family of optocouplers, specifically designed for industrial and commercial applications. It complements single and dual-channel variants like the ILD30 series by offering integrated quad functionality. This consolidation reduces component count and assembly complexity in designs requiring multiple isolated paths. The device leverages Vishay's semiconductor expertise to deliver reliable performance in harsh electrical environments.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other quad-channel photodarlington optocouplers from Vishay such as the ILQ31 or ILQ55, which share similar channel counts and package types. Verify equivalent isolation voltages and current transfer ratios when cross-referencing. Other manufacturers' quad optocouplers may require pin-to-pin verification and parameter matching.
