PS2506-1-A

Overview

The PS2506-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN Photodarlington output and utilizes a DIP-4 through-hole package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 200 mA, and a minimum current transfer ratio of 200%. The device supports a maximum forward current of 80 mA with a typical forward voltage of 1.4 V. It provides an insulation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high-speed isolation via NPN Photodarlington output configuration
• Ensures safety compliance with 5000 Vrms insulation voltage rating
• Delivers high current gain capability suitable for direct load driving

Applications

• Industrial control system signal isolation
• Power supply feedback loop monitoring
• Microcontroller interface protection circuits

Procurement Notes

Verify the specific suffix 'A' against the latest Renesas datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the DIP-4 through-hole package aligns with the PCB footprint constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a high current transfer ratio and robust isolation are required for single-channel applications. The NPN Photodarlington output offers higher sensitivity compared to standard phototransistors. Consider the thermal dissipation limits and operating temperature range during circuit design. Verify that the input forward current requirements fit within the specified 80 mA maximum limit for reliable operation.

Part Context

This component belongs to the PS2506 series of optically coupled isolators from Renesas Electronics. The series typically includes variants with different packaging options such as surface mount or leaded configurations. The PS2506-1-A specifically denotes the through-hole DIP version with standard electrical ratings. It serves as a fundamental building block for galvanic isolation in electronic systems requiring signal transmission across potential barriers.

Replacement Considerations

Consult official substitution lists for equivalent parts within the PS2506 family or compatible transistor output optocouplers. Verify pin compatibility and electrical parameter margins before swapping components. Ensure any replacement maintains the required 5000 Vrms insulation rating and NPN output type.
