PS8502L3-E3-AX

Overview

The PS8502L3-E3-AX is a high-speed analog output optocoupler manufactured by Renesas Electronics. It features an 8-pin DIP or SMD package with 8 mm creepage distance and 5000 Vrms isolation voltage. The device supports a data rate of 1 Mb/s and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a forward current of 16 mA, forward voltage of 1.7 V, reverse voltage of 5 V, output current of 8 mA, and power dissipation of 100 mW. The current transfer ratio is specified at 15%.

Feature Summary

• Provides high-speed analog signal transmission capability for precision applications
• Ensures robust electrical isolation with 5000 Vrms insulation voltage rating
• Features wide operating temperature range suitable for industrial environments
• Utilizes compact 8-pin packaging with extended creepage distance

Applications

• Industrial automation control systems requiring analog isolation
• Medical equipment needing high-voltage isolation safety
• Power supply feedback loops for precise voltage regulation
• Test and measurement instruments demanding low noise isolation

Procurement Notes

Verify the specific suffix E3 confirms RoHS compliance status before procurement. Confirm the package variant matches design requirements as datasheets may list multiple physical configurations. Ensure the analog output type aligns with circuit design needs rather than digital switching. Check latest manufacturer notices for any packaging or labeling changes that do not affect function.

Selection Notes

Select this component when analog signal integrity is critical over standard digital optocouplers. The 1 Mb/s speed supports moderate bandwidth applications. Consider the 8 mA output current limit for load driving capabilities. The wide temperature range allows operation in harsh industrial conditions without derating concerns.

Part Context

This part belongs to the PS8502 series of high-speed photocouplers from Renesas. It shares family characteristics with variants like PS8502L1 and PS8502L2 but differs in output configuration and packaging options. The series is designed for applications requiring fast response times and high isolation reliability in compact form factors.
