APS2241SX

Overview

The Panasonic APS2241SX is a high-speed photodiode output optocoupler featuring an AlGaAs LED and integrated signal processor. It supports data transmission rates up to 20 Mbps with a single channel configuration. The device provides robust electrical isolation of 3750 Vrms and withstands common mode transients at 15 kV/µs. Key electrical parameters include a power dissipation of 40 mW, a reverse voltage of 5 V, and a maximum operating temperature of +105°C. It utilizes a compact SOP-5 package measuring 4.4 mm x 4.3 mm x 2.1 mm.

Feature Summary

• Integrates AlGaAs LED with smart photoIC for high-speed signal processing
• Provides high noise immunity against common mode transients
• Ensures reliable electrical insulation between input and output circuits

Applications

• High-speed communication in industrial equipment
• Signal transmission for programmable logic controllers (PLC)
• Motor control system interfaces

Procurement Notes

Verify the component status carefully before procurement. Official distributor information indicates the lifecycle status as NRND (Not Recommended for New Designs). This designation implies that while existing stock may be available, new design-in activities are discouraged. Confirm availability through authorized channels and ensure the specific package variant matches the required footprint for existing designs.

Selection Notes

Select this component when high-speed digital isolation is required within space-constrained environments. The 20 Mbps rate suits applications needing faster response than standard logic couplers. Ensure the circuit design accommodates the 3750 Vrms isolation rating and the 40 mW power dissipation limit. Verify compatibility with the 2.7V to 5.5V supply range and the specific SOP-5 pinout configuration.

Part Context

This part belongs to the Panasonic APS2 series of PhotoIC couplers. The series combines aluminum gallium arsenide LEDs with intelligent optical sensors and signal processors. These components are engineered for industrial automation, offering superior speed and noise resistance compared to conventional optocouplers, specifically targeting PLC and motor drive applications.

Replacement Considerations

Due to the NRND status, identify alternative high-speed photodiode output optocouplers from Panasonic or other manufacturers. Ensure substitutes match the 20 Mbps speed, 3750 Vrms isolation, and SOP-5 package dimensions. Cross-reference pinouts and electrical characteristics to maintain system integrity.
