High-speed digital isolator for industrial and automotive signal paths
The Toshiba TLP2710(TP4,E is a single-channel, high-speed logic-output optocoupler rated for 5MBd data rate and 5000Vrms isolation voltage. Propagation delay is 250ns max, and common-mode transient immunity is 25kV/µs minimum, which keeps the output clean during fast switching events on the high-voltage side.
The 5000Vrms isolation rating qualifies this optocoupler for reinforced insulation in mains-connected equipment, such as industrial drives and grid-tied power supplies. The 25kV/µs common-mode transient immunity (CMTI) is the spec that matters when the isolation barrier sees fast voltage slew from a switching power stage or an IGBT bridge. With 11ns rise and 13ns fall times, the output edges stay clean enough for 5MBd signalling without extra schmitt-trigger buffering on the receiving side.
Temperature range and supply compatibility
The 2.7V to 5.5V supply range means it can be powered from a 3.3V rail in a modern MCU interface or from a 5V rail in legacy PLC backplanes. The forward diode requires 1.9V typical and 8mA max input current, which is within the drive capability of most 3.3V CMOS outputs.
Package and mounting
Supplied in a 6-SOIC wide-body package (7.50mm body width) with a 6-SO supplier device code. Surface-mount only. The wide creepage distance supports the 5000Vrms rating.
