Overview
The PS2841-4B-F3-AX is a high-isolation, four-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output configuration housed in a 12-pin SSOP package. The device provides an insulation voltage of 1500 Vrms and supports a maximum forward current of 20 mA with a forward voltage of 1.2 V. The collector-emitter saturation voltage is typically 300 mV, and the unit operates within a temperature range of -40°C to +100°C.
Feature Summary
- Provides four independent channels for signal isolation in a compact surface-mount package
- Features high insulation voltage capability for robust noise immunity
- Utilizes NPN phototransistor outputs for standard logic interfacing
Applications
- Industrial automation control systems
- Power supply feedback loops
- Communication interface isolation
Procurement Notes
Verify the specific suffix 'F3' against the official Renesas datasheet to confirm tape-and-reel packaging specifications and pinout compatibility. Ensure the component matches the required RoHS compliance status for your target market regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when multi-channel isolation is required within space-constrained designs. The 12-SSOP package offers a balance between channel density and thermal performance. Consider the 1500 Vrms insulation rating for applications requiring significant potential difference between input and output circuits. Verify that the NPN output type aligns with the downstream logic requirements of the system design.
Part Context
This part belongs to the PS2841 series of high-isolation optocouplers from Renesas. The series is designed for applications demanding reliable electrical isolation between low-voltage control circuits and higher-voltage power stages. The four-channel variant allows for parallel signal transmission while maintaining galvanic separation across all channels simultaneously.
Replacement Considerations
Direct replacements must match the 12-SSOP footprint and 1500 Vrms insulation rating. Verify that substitute components offer comparable current transfer ratios and operating temperature ranges. Check for pin-to-pin compatibility to avoid PCB redesign efforts during component substitution.
