Overview
The PS2806-4 is a four-channel optocoupler manufactured by CEL, featuring GaAs LEDs and NPN silicon Darlington phototransistors. It provides high isolation voltage of 2500 Vrms and supports AC input response. The device offers a typical current transfer ratio of 2000% at IF = ±1 mA and VCE = 2 V. It is housed in a compact 16-pin SSOP package with a 1.27 mm pin pitch, designed for high-density applications.
Feature Summary
- High isolation voltage capability of 2500 Vrms
- AC input response functionality
- High current transfer ratio of 2000% typical
- Compact 16-pin SSOP package design
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microprocessor interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix (e.g., -A) against the manufacturer's official datasheet to confirm lead-free status and RoHS compliance. Ensure the ordering number matches the required tape product configuration, such as PS2806-4-F3 or F4, if reel packaging is necessary for automated assembly processes.
Selection Notes
Select this component when four isolated channels are required within a single package to save board space. The Darlington output structure provides high gain suitable for driving loads directly. Verify that the operating temperature range of -55°C to 100°C meets the environmental requirements of the target application.
Part Context
This part belongs to the NEC PS2806 series, now produced by CEL. The series includes single-channel (PS2806-1) and four-channel variants. These devices are designed for high-density applications where small footprint and high isolation are critical. The package offers a shield effect to cut off ambient light interference.
Replacement Considerations
Direct substitutes include other four-channel Darlington output optocouplers with similar 2500 Vrms isolation and 16-pin SSOP packages. Verify pinout compatibility and current transfer ratio specifications before substitution. Check for equivalent safety certifications such as UL and VDE recognition.
