50Mbps photocouplers boast reinforced isolation

November 04, 2016 // By Julien Happich
The TLP2767 photocoupler from Toshiba Electronics Europe supports data rates up to 50Mbps while enforcing a creepage and clearance distance of 8mm and boasting an isolation thickness of 0.4mm for reinforced isolation. It is housed in an SO6L package and guarantees isolation voltage of 5000Vrms (min).

The TLP2367 is housed in a 5-pin small SO6 package, guaranteeing creepage and clearance distance of 5mm (min) and isolation voltage of 3750V rms (min.). Both packages have a low profile of 2.3mm and meet international safety standards including UL1577 and EN60747-5-5.

The photocouplers guarantee a propagation delay time of 20ns, maximum, a maximum pulse width distortion of 8ns and a propagation delay skew under 10ns. They can be used to reduce the dead time of various interfaces including inverters, which can contribute to improving the power efficiency of systems.

Both devices use Toshiba's original high output infrared LEDs on the input side. Threshold input current is approximately 20% lower than Toshiba’s older TLP117 product. On the output side, a photo detector IC fabricated with a CMOS process reduces the supply current by approximately 50%, compared to the TLP117. Both photocouplers can contribute to lowering the operation voltage of systems with guaranteed supply voltage of 2.7V to 5.5V, at temperatures up to 125 degrees Celsius. Applications include programmable logic controllers (PLC), I/O interface, photovoltaic (PV) inverters and FA inverters.
