ILD621-X001

Transistor, Photovoltaic Output Optoisolators Overview

The ILD621-X001 is a dual-channel phototransistor optocoupler manufactured by Vishay Semiconductor Opto Division. It utilizes Gallium Arsenide (GaAs) infrared emitters paired with high-gain NPN silicon phototransistors to provide electrical isolation. The device offers an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a typical rise time of 2.8μs, a maximum input current of 60mA, and a maximum forward voltage of 1.3V. The component is housed in an 8-pin surface-mount package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'X001' against official Vishay documentation to confirm the exact pinout and reel specifications. Ensure compatibility with surface-mount assembly processes. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential parameter updates before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. Consider the 5300Vrms isolation rating for high-voltage safety compliance. Evaluate the 2.8μs rise time against system speed requirements. Compare CTR matching needs against single-channel alternatives to determine if the multi-channel configuration reduces overall bill of materials complexity.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD621 belongs to Vishay's family of multi-channel phototransistor optocouplers, which also includes quad-channel variants like the ILQ621. These devices share similar internal technologies using GaAs emitters and NPN phototransistors. The dual-channel design specifically targets applications where space savings and matched channel characteristics are prioritized over single-channel flexibility.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Official substitutes include the ILD621GB for lead-free compliance or the ILQ621 series for quad-channel requirements. Verify pinout compatibility and isolation voltage ratings before substitution. Check for package dimension differences between DIP and SMD variants if physical constraints apply.
