ILD74-X009T

Transistor, Photovoltaic Output Optoisolators Overview

The ILD74-X009T is a dual-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an infrared LED coupled to two NPN phototransistors in a surface-mount package. The device provides high isolation voltage of 5300Vrms between input and output channels. Key electrical parameters include a minimum current transfer ratio of 12.5% at 16mA forward current, maximum collector-emitter voltage of 20V, and typical turn-on/turn-off times of 3µs. It operates within a temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration with independent phototransistor outputs for simultaneous signal isolation
• High insulation voltage capability ensuring safe separation between input and output circuits
• Fast switching performance suitable for digital logic transmission applications

Transistor, Photovoltaic Output Optoisolators Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical isolation between circuit stages or system components

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix X009T corresponds to the required SMD-8 packaging and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the manufacturer designation matches Vishay Semiconductor Opto Division to avoid counterfeit or obsolete variants.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. Consider the 20V output voltage limit and 12.5% CTR minimum for compatibility with downstream logic levels. Evaluate thermal management needs given the 400mW power dissipation rating and wide operating temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILD74 belongs to Vishay's family of transistor-output optocouplers designed for general-purpose isolation. Unlike single-channel variants such as the CNY17 series, this part integrates two isolated channels in one package. It serves as a solution for multi-signal isolation where board space is constrained compared to through-hole DIP packages.
