ACPL-227-50BE

Transistor, Photovoltaic Output Optoisolators Overview

The ACPL-227-50BE is a dual-channel transistor output optocoupler from Broadcom's ACPL series, housed in an SOIC-8 surface-mount package. It provides 3750 Vrms isolation voltage and supports DC input signals. The device features NPN phototransistor outputs with a minimum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. Key electrical parameters include a forward voltage of 1.4 V, a forward current rating of 50 mA, and a current transfer ratio ranging from 130% to 260%. Typical switching characteristics include a rise time of 2 μs and a fall time of 3 μs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High insulation voltage capability for safety-critical applications
• NPN phototransistor output structure for robust switching

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Solid-state relay driver circuits
• General-purpose digital signal isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '50BE' against the manufacturer's official datasheet to confirm exact binning and packaging specifications. Ensure that the SOIC-8 footprint matches the target PCB design constraints. Confirm compliance requirements such as RoHS status and specific safety certifications (UL, EN, IEC) required for the end application before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation within a compact SOIC-8 package is required. The 3750 Vrms isolation rating suits high-voltage separation needs. Consider the 130%-260% current transfer ratio range for logic interface compatibility. Verify that the 2 μs rise time meets the system's speed requirements, as it is slower than high-speed logic couplers.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the Broadcom ACPL series of optocouplers, designed for general-purpose isolation tasks. The ACPL-227 variant specifically offers dual channels, distinguishing it from single-channel models like the ACPL-217. It utilizes standard NPN phototransistor technology rather than high-speed or linear amplifier architectures found in other series members.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting the manufacturer's official replacement guide or equivalent parameter matching based on isolation voltage, CTR, and package type.
