ILQ615-1

Transistor, Photovoltaic Output Optoisolators Overview

The ILQ615-1 is a quad-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features four independent NPN phototransistor outputs driven by GaAs infrared LEDs, providing electrical isolation in a 16-pin PDIP package. The device supports a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA per channel. Key electrical parameters include an isolation voltage of 5300 Vrms, a typical rise time of 2.8 µs, and a forward voltage of 1.3 V at a maximum forward current of 60 mA. The unit operates within a temperature range of -55°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code (e.g., X009) against the manufacturer datasheet to ensure correct Current Transfer Ratio (CTR) binning and packaging type. Confirm that the 16-pin DIP form factor matches the target PCB footprint. Check RoHS compliance status and lead-free soldering requirements prior to ordering. Ensure the selected variant meets the required operating temperature range for the intended application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed within a single package to reduce board space. Compare the CTR specifications of available suffixes to match the drive current requirements of the receiving circuitry. Consider the 5300 Vrms isolation rating for applications demanding high safety margins between input and output domains. Evaluate the thermal dissipation capabilities if multiple channels are operated simultaneously at high currents.

Transistor, Photovoltaic Output Optoisolators Part Context

The ILQ615 series belongs to Vishay's family of multi-channel phototransistor optocouplers. It shares architectural similarities with the ILD615 dual-channel variant but offers four isolated paths. This series is designed for general-purpose isolation tasks where compactness and high reliability are prioritized over ultra-high speed or logic-output compatibility.
