ISOM8117DFHRQ1

Transistor, Photovoltaic Output Optoisolators Overview

The ISOM8117DFHRQ1 is an automotive-grade, single-channel transistor-output optocoupler from Texas Instruments. It features a DC-input configuration with a phototransistor output housed in a SOIC-4 surface-mount package. The device provides high isolation capability of 5000 Vrms and supports a maximum collector-emitter voltage of 80 V. Key electrical parameters include a forward current of 20 mA, a typical current transfer ratio of 300%, and propagation delays characterized by rise and fall times of 3.2 µs and 4 µs respectively. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'DFHR' to confirm the reel packaging format and tape width specifications required for automated assembly. Ensure the component matches the AEC-Q100 qualification status for automotive applications. Cross-reference the datasheet revision to confirm the exact current transfer ratio and isolation voltage ratings prior to integration into final designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this model when high isolation voltage (5000 Vrms) is required compared to standard 3750 Vrms alternatives. The 20 mA forward current specification differs from higher-current variants like the ISOM8117DFGR. Consider the SOIC-4 footprint and thermal dissipation limits of 290 mW for PCB layout planning. Verify compatibility with the target switching speed requirements given the 3.2 µs rise time.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the ISOM8117-Q1 series of isolated transceivers designed for robust automotive environments. It complements other devices in the family that may offer different channel counts or lower isolation ratings. The series focuses on providing reliable galvanic isolation for safety-critical systems in electrified vehicles and industrial machinery.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The ISOM8117DFGR offers similar functionality but lacks automotive qualification and has a lower 3750 Vrms isolation rating. The ISOM8110DFHRQ1 is a related automotive part but specifies only 3750 Vrms isolation. Direct substitution requires verifying that the reduced isolation voltage of alternatives meets the system safety requirements.
