Overview
The PS2841-4A-F3-AX is a four-channel transistor output optocoupler manufactured by Renesas Electronics. It features NPN phototransistor outputs and provides an insulation voltage of 1500 Vrms. The device operates with a maximum forward current of 20 mA and a forward voltage of 1.2 V. It supports a collector-emitter voltage of 70 V and a maximum collector current of 20 mA. The current transfer ratio ranges from 100% to 400%. Power dissipation is rated at 40 mW, with an operating temperature range from -40°C to +100°C.
Feature Summary
- Four independent channels for multi-signal isolation
- NPN phototransistor output configuration
- High insulation voltage capability
Applications
- Industrial control systems
- Power supply feedback loops
- Signal isolation in noisy environments
Procurement Notes
Verify the specific suffix F3-AX against the official Renesas datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before procurement.
Selection Notes
Select this component when four isolated channels are required within a single package. The 1500 Vrms insulation rating suits applications needing moderate isolation strength. Verify that the 20 mA collector current limit meets the load requirements of the receiving circuitry. Consider the -40°C to +100°C temperature range for environmental suitability.
Part Context
This part belongs to the PS2841-4A series of high-speed, four-channel optocouplers. It is designed for general-purpose isolation tasks where multiple signals need to be transmitted across an isolation barrier. The series offers a compact solution compared to using discrete single-channel devices.
Replacement Considerations
Check for direct pin-compatible replacements such as other PS2841 variants or equivalent quad-channel optocouplers from other manufacturers. Verify electrical parameters like CTR and isolation voltage match exactly.
