ACPL-214-56AE

Transistor, Photovoltaic Output Optoisolators Overview

The ACPL-214-56AE is a single-channel phototransistor output optocoupler manufactured by Broadcom Limited. It provides electrical isolation with a voltage rating of 3000Vrms. The device supports both AC and DC input signals. Key electrical parameters include a minimum current transfer ratio of 50% at 1mA input current, with a maximum CTR of 250%. The typical turn-on delay time is 3 microseconds, and the turn-off time is 2 microseconds. It features a maximum forward current of 50mA and can withstand a maximum output voltage of 80V.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage galvanic isolation between input and output circuits
• Capable of processing both alternating current and direct current input signals
• Features fast switching speeds suitable for digital signal transmission

Transistor, Photovoltaic Output Optoisolators Applications

• AC mains power supply monitoring
• Industrial control systems requiring isolated signal interfaces
• Microcontroller input interfacing for high-voltage environments

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '56AE' to ensure correct packaging and tape-and-reel configuration as defined by Broadcom. Confirm that the 3000Vrms isolation rating meets the safety requirements of the target application. Check for RoHS compliance status if required by local regulations. Ensure the SOIC-4 package footprint matches the PCB design constraints.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel of isolation is sufficient for the circuit design. The phototransistor output requires a pull-up resistor for proper logic level translation. Consider the 50mA forward current limit when designing the input series resistor. Verify that the 80V maximum output voltage exceeds the load voltage in the application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ACPL-214 family of half-pitch phototransistor optocouplers designed for AC input applications. The family offers compact SOIC-4 packaging to save board space. Broadcom utilizes proprietary LED and photodetector technology to achieve consistent current transfer ratios across temperature ranges.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements must match the 3000Vrms isolation voltage and SOIC-4 package. Verify pinout compatibility to avoid circuit damage. Check that substitute devices offer similar current transfer ratios and switching times.
