What the 10 MBd data rate and open collector output mean for your design
The TLP2362(TPR,E is a 1-channel Toshiba optocoupler in a 5-lead 6-SOIC surface-mount package, rated for 10 MBd data rate with an open collector output. That data rate places it squarely in the range for industrial fieldbus isolation — Profibus, DeviceNet, and similar 5–20 MBd links — without the cost of a full digital isolator. The open collector output lets you wire-OR multiple outputs or pull up to a different supply voltage than the input side, which is handy when the receiving logic runs at a different rail than the transmitter. Propagation delay is 100 ns max (tpLH / tpHL), and rise/fall times are 30 ns typical — fast enough for 10 MBd signaling with reasonable timing margin for most industrial controllers.
Isolation and transient immunity for noisy environments
Isolation is rated at 3750 Vrms — enough for reinforced insulation in mains-connected equipment like motor drives, industrial power supplies, and PLC I/O modules. Common-mode transient immunity is specified at 20 kV/µs minimum, which means the part will hold its output state when a fast voltage transient slams across the isolation barrier. That spec is the one that separates a reliable fieldbus node from one that glitches during a motor start or inverter switching event. The full industrial range also covers factory-floor enclosures that see 85°C ambient plus self-heating from adjacent power components.
Current ratings and forward voltage
Output side can sink 25 mA per channel. These are standard figures for this class of optocoupler — no surprises for BOM budgeting. The DC input type means it handles steady-state logic levels, not AC-coupled signals.
