Rated for 3750Vrms isolation with a minimum common-mode transient immunity of 15kV/µs, this part maintains signal integrity across the galvanic barrier in high-noise automotive environments like traction inverter gate drives. ## Output drive and timing budget The open collector output sinks up to 25 mA per channel from a 4.5V to 5.5V supply — enough to drive a downstream logic input or a small relay coil directly without a buffer. Typical rise/fall times are 90ns and 30ns respectively, so the 100ns propagation delay is the dominant term in the loop timing budget. Input-side forward voltage is 1.75V max at 25 mA forward current — standard 3.3V or 5V logic can drive it through a series resistor. The 1/0 input-side/side-2 count confirms this is a unidirectional isolator. Housed in a 6-SOIC package with 5 leads (0.179\" body width, 4.55mm), the TLX9378(TPL,F uses a surface-mount footprint compatible with standard SOIC-6 land patterns. The supplier device package is listed as 6-SO, 5 Lead — the missing pin is the no-connect on position 6. ## Active lifecycle — no LTB pressure The AEC-Q101 qualification means it has passed automotive-grade reliability testing including high-temperature operating life, temperature cycling, and ESD sensitivity screening per AEC-Q101-006.","metaTitle":"Toshiba TLX9378(TPL,F Photocoupler, 10MBd, 3750Vrms","metaDescription":"Toshiba TLX9378(TPL,F automotive photocoupler, 10MBd data rate, 3750Vrms isolation, open collector output, -40°C to 125°C.

The key difference is propagation delay: TLX9304 is 400ns/550ns vs TLX9378's 100ns/100ns, so the TLX9304 is slower and may not meet timing in high-speed links. The output drive is also lower at 15 mA vs 25 mA. They are footprint-compatible but not drop-in replacements without checking the timing budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLX9378~1TPL~6F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLX9378~1TPL~6F when reusing this data.
