Description
The RV1S2951A is an optically coupled transistor-output isolator featuring a high current transfer ratio at a sub-mA of the forward current. The RV1S2951A consists of an AlGaAs LED on the input side and an NPN silicon phototransistor on the output side in an ultra-small flat-lead package to reduce the mounting area by 30 % compared with the SSOP for the PS28xx series keeping a 4mm creepage distance.

- White PaperThere has been a growing demand for devices that reduce part count and size to achieve downsizing in building management, HVAC systems, power supplies, and industrial equipment. Furthermore, optimizing the design of the optocouplers’ input current and extending their lifespan in insulated parts of the equipment is desirable. This paper focuses on transistor output couplers that meet these market needs, featuring ultra-low input current and a high optical transmission coefficient, i.e. high current transfer ratio.

- White PaperIndustrial automation and solar inverter systems face demands for both size reduction and compliance with stricter safety standards. This paper explains how next-generation isolation devices enable smaller board layouts while meeting increased creepage and clearance requirements, helping engineers optimize designs without compromising safety or performance.
