PS2562L1-1-A

Overview

The PS2562L1-1-A is a single-channel NPN Photodarlington output optocoupler manufactured by Renesas Electronics. It features a 4-pin DIP package with through-hole mounting and provides 5000 Vrms isolation voltage. The device supports a maximum forward current of 80 mA and a collector current of 200 mA, with a collector-emitter saturation voltage of 1 V. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN photodarlington transistor for high current transfer capability
• Designed for surface mount or leaded applications in compact packages

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm lead-free status and exact packaging configuration. Ensure the selected variant matches the required insulation voltage and thermal performance specifications for the target application environment.

Selection Notes

Select this component when high current transfer ratios are needed in a small footprint. Compare the 200% to 2000% CTR range against load requirements. Verify that the 5000 Vrms isolation rating meets safety standards for the intended circuit separation needs.

Part Context

This part belongs to the PS2562L series of optocouplers from Renesas, formerly NEC Electronics. The series is known for combining LED inputs with photodarlington outputs to provide robust signal transmission across isolated boundaries in various electronic assemblies.

Replacement Considerations

Cross-reference with PS2562L1-1-V-F4 for surface mount equivalents. Check PS2562L2-1-V-A for similar performance in gull-wing packages. Confirm pinout compatibility before substitution.
