PS2933-1-V-AX

Overview

The PS2933-1-V-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a compact surface-mount package designed for high-density mounting. The device provides electrical isolation with a rated insulation voltage of 2500 Vrms. Key electrical characteristics include a maximum collector-emitter voltage of 350 V, a forward current rating of 50 mA, and a minimum forward voltage of 1.3 V. The unit exhibits a current transfer ratio ranging from 100% to 400%, with typical rise and fall times of 20 µs and 5 µs respectively.

Feature Summary

• Integrates a GaAs light emitting diode and an NPN silicon phototransistor in a single package
• Provides high collector-to-emitter voltage capability for robust signal isolation
• Features high isolation voltage rating suitable for demanding industrial environments

Applications

• Industrial automation control systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix designation carefully during procurement, as variants such as PS2933-1-AX and PS2933-1-F3 exist with different packaging or tape-and-reel specifications. Confirm RoHS compliance status and lead-free certification directly with the manufacturer or authorized distributors prior to ordering. Ensure the selected variant matches the required mounting style and reel quantity for the intended production line setup.

Selection Notes

Select this component when a high voltage isolation rating of 350 V is required alongside standard transistor output characteristics. Consider the 2500 Vrms insulation rating for applications involving significant potential differences between input and output circuits. Evaluate the current transfer ratio range to ensure adequate gain for the specific load conditions. Verify that the surface-mount package dimensions fit the available PCB real estate constraints.
