Overview
The PS2933-1-V-F3-AX is a transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a 4-pin SSOP package. The device provides an insulation voltage of 2500 Vrms. Key electrical parameters include a collector-emitter voltage of 350 V, a maximum collector current of 60 mA, and a forward voltage of 1.3 V at a forward current of 50 mA. The current transfer ratio ranges from 100% to 400%. Switching characteristics specify a rise time of 20 us and a fall time of 5 us.
Feature Summary
- Integrates a GaAs light emitting diode with an NPN silicon phototransistor for high-density mounting applications.
- Housed in an ultra-small flat-lead package that reduces mounting area compared to standard series.
- Provides high isolation voltage capability for signal transmission across isolated circuits.
Applications
- Hybrid ICs
- Telephone exchange equipment
- Fax machines
Procurement Notes
Verify the specific suffix -V-F3-AX against official documentation to confirm reel packaging and RoHS compliance status. Confirm availability as this variant may be subject to restricted supply or limited distribution channels depending on regional inventory constraints.
Selection Notes
Select this component when a compact form factor is required alongside high collector-emitter voltage ratings. Ensure the design accommodates the specified switching times and current transfer ratio variations. Verify thermal dissipation requirements within the SSOP package constraints for the intended operating environment.
Part Context
This part belongs to the PS2933-1 series of optically coupled isolators. It is designed for applications requiring electrical isolation between input and output circuits while maintaining a small footprint. The series utilizes a GaAs LED and NPN phototransistor configuration.
Replacement Considerations
Consult official substitution guides for equivalent parts. Cross-reference specifications such as isolation voltage, CTR, and package dimensions before implementing any alternative components.
