Overview
The TLP124(BV-TPL,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an MFSOP-6 (4-pin surface mount) package with a gull-wing configuration. Key electrical parameters include a maximum 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 saturation voltage of 400mV max. The current transfer ratio ranges from 100% to 1200% at 1mA input. Operating temperature spans -55°C to 100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
- Designed for surface-mount assembly in compact electronic systems requiring reliable signal transmission across isolated domains.
- Offers low input current requirements suitable for direct interfacing with various logic families.
Applications
- AC/DC input modules in industrial control systems
- Programmable logic controllers (PLCs)
- Telecommunication equipment interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix BV-TPL,F matches design requirements. Check for end-of-life status or minimum order quantity restrictions that may impact supply chain continuity. Ensure RoHS compliance documentation is available for regulatory adherence.
Selection Notes
Select this component when a small footprint surface-mount optocoupler with moderate speed and high isolation voltage is required. Consider the 8μs switching speed limitations compared to faster logic outputs. Evaluate thermal management needs within the specified operating temperature range. Verify pin compatibility with existing PCB layouts designed for MFSOP-6 packages.
Part Context
This part belongs to the TLP124 series of transistor output optocouplers from Toshiba. The series includes variants with different packaging and tape/reel options. The TLP124 family is widely recognized for general-purpose isolation applications in consumer and industrial electronics. This specific variant includes tape and reel packaging for automated assembly.
Replacement Considerations
Direct substitutes include other Toshiba TLP124 variants such as TLP124(F) or TLP124(BV). Cross-manufacturer replacements require verification of pinout, isolation voltage, and CTR specifications. Ensure any alternative maintains the same MFSOP-6 footprint and electrical characteristics.
