ILQ620

Transistor, Photovoltaic Output Optoisolators Overview

The ILQ620 is a quad-channel phototransistor optocoupler manufactured by Vishay Semiconductor Opto Division. It features four independent channels, each utilizing an inverse parallel GaAs infrared LED emitter coupled to a high-gain NPN phototransistor output. The device provides electrical isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a forward current rating of 60 mA. The typical rise time is 2.8 µs, while the fall time is 11 µs. The current transfer ratio ranges from 100% to 600%. The component operates within a temperature range of -55°C to +100°C and is available in a 16-pin DIP package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., GB, X009) against the required packaging and compliance standards. Confirm availability status as some variants may be discontinued or restricted. Ensure the selected part number matches the exact pin configuration and thermal characteristics required for the target PCB layout. Cross-reference the datasheet revision date to guarantee parameter accuracy.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed within a single package footprint. Consider the 5300 Vrms isolation rating for safety-critical applications. Evaluate the 100% to 600% CTR range to ensure sufficient drive capability for downstream logic. Verify that the 16-pin DIP package fits the assembly constraints and that the operating temperature range meets environmental requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILQ620 belongs to Vishay's ILQ series of multi-channel optocouplers. It shares architectural similarities with the ILD620 but differs in input/output configurations. This family is designed for applications requiring compact, high-density isolation solutions. The device complements Vishay's broader portfolio of discrete optoelectronic components used in industrial and consumer electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct substitutes within the ILQ series, such as the ILQ621GB, which offers similar quad-channel functionality. Verify pin compatibility and electrical parameter equivalence before substitution. Consult official Vishay documentation for approved replacement lists to ensure performance consistency.
