Reinforced isolation in an 8-SMD gull-wing package
The PS8502L2-E3-AX: The Renesas NEPOC PS8502L2--AX is a single-channel optocoupler rated for 5000Vrms isolation, with a transistor output and DC input. It comes in an 8-SMD gull-wing package for surface-mount assembly, operating from -55°C to 100°C. This part is from the NEPOC series, Renesas's standard optocoupler family for industrial and power-conversion isolation.
The 5000Vrms isolation rating qualifies this optocoupler for reinforced insulation in mains-referenced circuits and industrial drives where the primary-secondary barrier must hold off transient overvoltages. The 8-SMD gull-wing package provides the surface-mount footprint with adequate pin spacing for the rated voltage.
Switching speed and drive margin for digital isolation
Typical turn-on time is 220ns and turn-off time is 350ns, which sets the practical data rate ceiling around a few hundred kilohertz — suitable for isolating digital status signals, fault flags, or slow PWM gate drives. The minimum current transfer ratio of 15% at 16mA forward current means the output transistor can sink 8mA per channel (the rated output current) with adequate base drive. If your load requires more than 8mA, plan on an external pull-up or a buffer stage.
