PS2513-1-A

Overview

The PS2513-1-A is a high-speed switching optocoupler featuring a GaAs infrared LED and an NPN silicon phototransistor. It provides a high isolation voltage of 5,000 Vrms and a collector-to-emitter voltage of 120 V. The device operates with a typical propagation delay of 3 µs and a rise/fall time of 3 µs. It supports a collector current of 50 mA and offers a current transfer ratio of 100% to 600%. Packaged in a 4-pin DIP, it ensures reliable signal transmission across isolated circuits.

Feature Summary

• High-speed switching capability for rapid signal transmission
• High isolation voltage rating for robust circuit protection
• Integrated GaAs LED and NPN phototransistor design

Applications

• Industrial automation control systems

• Microcomputer input/output interface circuits

Procurement Notes

Verify the suffix -A indicates the specific packaging variant, typically standard tube packaging, as per Renesas documentation. Confirm the datasheet revision matches your design requirements. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the part number with official Renesas distributors to avoid counterfeit components. Check for any specific handling or storage instructions provided in the product specifications.

Selection Notes

Select this component when high-speed digital isolation is required between low-voltage logic and higher-voltage power stages. The 120 V collector-emitter voltage allows for driving moderate loads directly. Consider the 5,000 Vrms isolation barrier for safety-critical applications. Evaluate the current transfer ratio range to ensure sufficient noise margin in noisy environments. Compare propagation delays against system timing constraints.

Part Context

This part belongs to the PS2513 series of high-speed optocouplers from Renesas Electronics. The series is designed for applications requiring fast response times and high reliability. The PS2513-1-A variant specifically denotes the standard package configuration within this family, maintaining consistent electrical characteristics across the model line.

Replacement Considerations

Direct substitutes include the PS2513L-1 for leaded variants. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage before substitution. Consult Renesas documentation for approved alternative part numbers.
