PS2505L-4-E3-A

Overview

The PS2505L-4-E3-A is a quad-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Current transfer ratio ranges from 80% to 600%. Typical switching times are 3 µs rise and 5 µs fall. It operates within a temperature range of -55°C to +100°C and is housed in a 16-SMD surface-mount package.

Feature Summary

• Quad-channel configuration for multi-signal isolation
• High insulation voltage rating for safety separation
• NPN phototransistor output stage
• Surface-mount packaging for automated assembly

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller input/output isolation
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix E3-A against official Renesas documentation to confirm compliance details and pinout compatibility. Confirm availability status as distribution data may vary. Ensure the selected variant matches the required channel count and package type for the target PCB design. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when four isolated channels are required in a compact surface-mount form factor. The 80 V collector-emitter voltage supports standard logic-level switching applications. Verify that the 50 mA collector current meets the load requirements. Consider the 5000 Vrms insulation rating for safety-critical interfaces between low-voltage control circuits and higher-voltage power stages.

Part Context

This part belongs to the PS2505L series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The quad-channel variant integrates four independent optocouplers into a single package, reducing board space compared to using individual single-channel devices. It complements other variants in the family offering different channel counts or package styles.

Replacement Considerations

Direct substitutes include the PS2505L-4-A. Verify pinout and electrical specifications match before substitution. Check for updated lifecycle status such as NRND designation which may affect long-term supply.
