Overview
The PS2841-4A-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 supports a maximum forward current of 20 mA with a forward voltage of 1.2 V. Collector-emitter saturation voltage is specified at 300 mV, while the collector-emitter voltage reaches 70 V. The current transfer ratio ranges from 100% to 400%. Power dissipation is limited to 40 mW, and it operates within a temperature range of -40°C to +100°C.
Feature Summary
- Provides electrical isolation for four independent signal channels
- Utilizes NPN phototransistor output configuration
- Ensures high insulation voltage capability
Applications
- Industrial control systems requiring multi-channel isolation
- Signal transmission between microcontrollers and peripheral devices
- Power supply feedback circuits
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component matches the required insulation voltage and channel count for your design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status before procurement.
Selection Notes
Select this component when four isolated channels are required in a compact form factor. Consider the 1500 Vrms insulation rating for safety-critical applications. Evaluate the 100% to 400% current transfer ratio to ensure adequate signal coupling efficiency for the intended load conditions and input drive capabilities.
Part Context
This part belongs to the PS2841 series of optocouplers designed for general-purpose isolation. It serves as a solution for transferring digital signals across isolation barriers while protecting sensitive control circuitry from high-voltage transients common in industrial and power electronics environments.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before replacing existing components in established designs.
