PS2562L1-1-K-A

Overview

The PS2562L1-1-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN photodarlington output and operates with a maximum forward current of 80 mA and a forward voltage of 1.4 V. The device provides high isolation capability with an insulation voltage of 5000 Vrms. Electrical performance includes a typical current transfer ratio of 2000%, a maximum collector-emitter voltage of 40 V, and a maximum collector current of 200 mA. Switching characteristics are defined by rise and fall times of 100 µs each. The component supports a power dissipation of 150 mW and functions within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage rating of 5000 Vrms for reliable signal transmission across electrical barriers
• NPN photodarlington output structure providing high current transfer ratio for efficient switching
• Surface mount gull-wing package design suitable for automated assembly processes

Applications

• Power supply circuits requiring galvanic isolation
• Programmable logic controller (PLC) input/output interfaces
• Industrial automation and factory automation equipment
• Office automation devices such as fax machines

Procurement Notes

Verify the specific suffix K-A against official Renesas documentation to confirm lead bending type and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet or product release notes. Check current availability status as distribution channels may indicate limited stock or special order requirements. Ensure the selected variant matches the required surface mount package style for PCB layout compatibility.

Selection Notes

Select this component when a high current transfer ratio is required for driving loads directly from low-current control signals. The 5000 Vrms isolation rating makes it suitable for applications demanding strict safety separation between primary and secondary circuits. Consider the 100 µs switching speed limitations if high-frequency operation is necessary, as faster alternatives exist in other series. Verify that the 40 V collector-emitter voltage meets the load requirements of the target circuit design.

Part Context

This part belongs to the PS2562L series of high isolation voltage darlington transistor type multi photocouplers. The series includes variants with different packages and ratings, such as the PS2562L2-1-V-F3-A which shares similar electrical characteristics but may differ in packaging or specific approval certifications. The PS2562L1-1-K-A specifically denotes the single-channel configuration with surface mount gull-wing leads.

Replacement Considerations

Cross-reference with PS2562L2-1-V-F3-A for similar electrical specifications. Verify pinout compatibility and package dimensions before substitution. Confirm that any alternative part meets the same 5000 Vrms isolation and 2000% CTR requirements.
