Product details

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. If your load requires more than 8mA, plan on an external pull-up or a buffer stage.

Frequently asked questions

What is the current transfer ratio of PS8502L2--AX?

The minimum current transfer ratio is 15% at a forward current of 16mA. This is the guaranteed floor for the output transistor to saturate with the rated load.

What is the switching speed of PS8502L2--AX?

This sets a practical data rate ceiling in the hundreds of kilohertz range for digital isolation applications.
