TLP124(BV-TPR,F)

Overview

The TLP124(BV-TPR,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED input coupled to a phototransistor output within a 6-SOP (MFSOP-4) surface-mount package. Key electrical specifications include a collector-emitter voltage of 80V, a maximum forward current of 50mA, and an isolation voltage of 3750Vrms. The device exhibits a typical rise/fall time of 8µs and a current transfer ratio ranging from 100% to 1200%. It operates within a temperature range of -55°C to 100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using an infrared LED and phototransistor configuration.
• Features low input current requirements suitable for direct interface with microcontrollers or logic gates.
• Offers robust insulation performance with a specified isolation voltage rating for safety-critical applications.

Applications

• AC/DC input modules in industrial control systems
• Programmable Logic Controllers (PLC) signal isolation
• Telecommunications equipment interface circuits

Procurement Notes

Verify the specific suffix BV-TPR against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Confirm RoHS compliance status and check for any obsolescence notices, as this component series may have limited availability or be designated for non-new designs. Ensure the ordering code matches the required packaging format for automated assembly processes.

Selection Notes

Select this component when a compact surface-mount solution is required for general-purpose signal isolation with moderate speed requirements. The 8µs switching speed is adequate for standard communication interfaces but may not suit high-frequency data transmission. Consider the 80V collector-emitter voltage limit when designing output stages to ensure operation within safe absolute maximum ratings under all expected load conditions.
