IL215AT

Transistor, Photovoltaic Output Optoisolators Overview

The IL215AT is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED coupled with an NPN phototransistor having a base terminal for enhanced switching performance. The device provides 4000Vrms isolation voltage and is housed in an 8-SOIC package. Key electrical parameters include a maximum collector-emitter voltage of 30V, a DC forward current of 60mA, and a typical forward voltage of 1.15V. The unit supports a collector current of 150mA with a saturation voltage of 400mV maximum. Operating temperature range spans from -40°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'AT' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 4000Vrms isolation rating meets the safety standards applicable to your target market, such as UL or VDE certifications. Ensure the 8-SOIC footprint matches the PCB layout constraints before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage combined with fast switching characteristics is required. The integrated base terminal allows for external biasing to optimize turn-off times compared to standard phototransistors. Consider the 8-SOIC package size if space is limited but higher pin count than SOIC-4 is acceptable. Evaluate thermal dissipation requirements within the specified operating temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

The IL215AT belongs to Vishay's IL21x series of optocouplers, which are designed for general-purpose isolation applications. This series typically includes variants like the IL216AT and IL217AT, differing primarily in isolation ratings or packaging options. These devices utilize standard GaAs LED technology paired with silicon photodetectors to ensure reliable signal transmission across isolated barriers.
