TLP124(BV,F)

Overview

The TLP124(BV,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a compact SOP-6 (MFSOP) surface-mount package with four leads. Key electrical specifications include a maximum isolation voltage of 3750 V ac, a typical rise time of 8 µs, and a typical fall time of 8 µs. The device supports a maximum forward input current of 50 mA with a maximum forward voltage of 1.3 V. The collector-emitter saturation voltage is typically low, ensuring efficient switching. The current transfer ratio ranges from 200% to 1200%, allowing for high gain in signal transmission applications.

Feature Summary

• Provides galvanic isolation between input and output circuits using a phototransistor configuration.
• Utilizes a mini-flat SOP-6 surface-mount package designed for automated assembly processes.
• Delivers fast switching performance with symmetric rise and fall times suitable for general-purpose digital signal isolation.

Applications

• General-purpose digital signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic gates
• Power supply feedback loops requiring basic isolation

Procurement Notes

Verify the specific suffix BV against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status as manufacturing standards may evolve. Check for obsolescence notices or end-of-life declarations prior to finalizing procurement plans. Ensure the selected packaging matches the required reel or tape specifications for the intended production line.

Selection Notes

Select this component when a standard transistor output optocoupler is required for basic isolation tasks. Consider the 3750 Vrms isolation rating for safety requirements. Evaluate the 8 µs switching speed against the system's data rate needs. Compare the SOP-6 footprint against available PCB space constraints relative to other packages like DIP-4.

Part Context

This part belongs to the TLP124 series of transistor output optocouplers from Toshiba. The series is characterized by its use in general-purpose isolation applications where moderate speed and high reliability are necessary. The BV suffix typically denotes specific packaging or environmental compliance variations within the broader product family.
