Toshiba Launches Industry-leading 50Mbps Photocouplers for High-speed Communications

New line-up includes product with creepage and clearance distance of 8mm and isolation thickness of 0.4mm for reinforced isolation

TOKYO—Toshiba Corporation’s (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the launch of industry-leading[1] photocouplers for high-speed communications at data rates up to 50Mbps. Shipments of the two new products “TLP2767” and “TLP2367” start from today.

“TLP2767” is the first 50Mbps product in the industry[1] to achieve both a creepage and clearance distance of 8mm and isolation thickness of 0.4mm for reinforced isolation. It is housed in an SO6L package and guarantees isolation voltage of 5000 Vrms (min). “TLP2367” is housed in a 5pin small SO6 package, guaranteeing creepage and clearance distance of 5mm (min) and isolation voltage of 3750Vrms. Both products are 2.3mm (max) low-height packages and meet international safety standards including UL1577 and EN60747-5-5.

The new photocouplers guarantee a propagation delay time of 20ns (max), pulse width distortion of 8ns (max) and propagation delay skew of 10ns (max). They can be used to reduce the dead time of various interfaces including inverters, which can contribute to improving the power efficiency of systems. On the input side, incorporation of Toshiba's original high output infrared LEDs reduce the threshold input current by approximately 20%, compared with Toshiba existing products[2]. On the output side, a photo detector IC fabricated with a CMOS process reduces the supply current by approximately 50%, compared with Toshiba existing products[2], which can contribute to lower power consumption and cost reduction of systems. Furthermore, they 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.
