5000Vrms isolation in a 6-SOIC — what this optocoupler is for
The Toshiba TLP2767(TP,E is a single-channel digital optocoupler with a push-pull output, designed for applications that require galvanic isolation between logic domains. Its 5000Vrms isolation rating targets industrial motor drives, servo controllers, PLC I/O modules, and medical power supplies where safety isolation is a regulatory requirement. The 50MBd data rate and 25kV/µs common-mode transient immunity make it suitable for high-speed digital interfaces such as fieldbus transceivers and isolated gate-drive signals, where fast switching edges must not corrupt the data stream.
Push-pull output and supply flexibility — BOM simplification
The push-pull output stage directly drives CMOS or TTL logic inputs without an external pull-up resistor, saving one component and one trace on the PCB. The 10 mA output current per channel is sufficient to drive a standard logic input or a small load resistor for signal termination.
Timing and transient immunity — the specs that matter in a noisy environment
In a motor-drive application where the PWM carrier runs at 10-20 kHz, the 20 ns skew is negligible relative to the switching period. The 25kV/µs minimum common-mode transient immunity is the spec to check against the inverter's dV/dt at the isolation barrier — if the IGBT or SiC FET switches at 50-100 V/ns, this part's CMTI margin is comfortable. The input is DC-coupled, so no AC-coupling capacitor is needed on the LED drive side.
Package and temperature grade — industrial and automotive environment fit
Housed in a 6-SOIC wide-body package (0.295", 7.50mm width), the TLP2767 provides the creepage and clearance distances required for reinforced isolation in 300VAC applications. Surface-mount assembly is standard for automated production lines. The 6-SO supplier device package is the same footprint used by many competing optocouplers, simplifying second-source qualification.
Lifecycle and compliance — active part, no LTB risk
RoHS compliance is confirmed, which keeps it eligible for EU-market equipment and most global environmental regulations. Cut Tape (CT) is also available for prototyping and low-volume builds.
