The Toshiba TLP2361(V4,E is a single-channel, high-speed digital optocoupler with a push-pull (totem-pole) output stage, delivering a data rate of 15 MBd across a 3750 Vrms galvanic isolation barrier.
The 15 MBd data rate supports common industrial fieldbus speeds: CAN at 1 Mbps, RS-485 at 10 Mbps+ with short cable runs, and isolated SPI clocks up to 10 MHz. The 80 ns max propagation delay (tpLH and tpHL) sets the timing budget for the loop — in a 10 MHz SPI link, that delay consumes roughly one clock period, so the master may need to insert a wait state or the designer should budget the propagation into the setup/hold margin. The 3 ns typical rise and fall times keep the signal edges sharp, minimising duty-cycle distortion when daisy-chaining multiple isolators.
In a motor drive or a switched-mode power supply, the primary-side ground can jump several hundred volts in a few nanoseconds. A CMTI of 20 kV/µs means the output stays in the correct logic state through that transient — no false edges, no corrupted data. For designs that already use a gate-drive optocoupler with similar CMTI, the TLP2361 is a natural companion for the feedback or communication channel.
Housed in a 6-SOIC package with 5 leads and a 4.55 mm body width, the TLP2361(V4,E shares the same footprint as many standard SO-6 optocouplers. It is a surface-mount device, shipped in Tube. The pinout is a single input LED (anode and cathode) on one side and a single push-pull output (VCC, GND, VO) on the other. The 5-lead variant omits the unused sixth pin, saving a trace on the board. No exposed pad — standard SOIC reflow profile applies.
It is ROHS3 compliant.
