Overview
The TLP187(V4-TPR,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a phototransistor in a compact SOP-4 package. Key electrical parameters include a collector-emitter voltage of 300V, an isolation voltage of 3750Vrms, and a typical forward voltage of 1.25V. The device supports a maximum DC forward current of 50mA and delivers an output current of 150mA. It features a minimum current transfer ratio of 1000% at 1mA input and operates within a temperature range of -55°C to 110°C.
Feature Summary
- High collector-emitter breakdown voltage suitable for high-voltage switching applications
- Enhanced insulation thickness compliant with reinforced insulation safety standards
- Compact surface-mount packaging designed for reduced installation height
Applications
- Programmable logic controller (PLC) output modules
- Factory automation equipment interfaces
- Air conditioning systems and home appliances
Procurement Notes
Verify the specific suffix V4 against official Toshiba documentation to confirm compliance with relevant regional safety standards such as UL or VDE. Ensure the SOP-4 footprint matches the target PCB design, noting the specific pinout configuration. Confirm that the operating temperature range meets the environmental requirements of the final assembly before procurement.
Selection Notes
Select this component when reinforced insulation and high voltage isolation are required in a small form factor. The high current transfer ratio allows for efficient driving with low input current. Consider the rise and fall times if signal speed is critical, as the Darlington structure may limit high-frequency performance compared to standard phototransistors.
Part Context
This part belongs to the TLP187 series of general-purpose optocouplers. It serves as a successor to older models like the TLP127, offering improved thermal stability and smaller dimensions. The series is designed to meet global safety certifications, making it suitable for industrial and consumer electronics requiring reliable galvanic isolation between control and load circuits.
Replacement Considerations
Officially documented substitutes include the TLP187(E and TLP187(TPL,E. Verify pin compatibility and insulation ratings when replacing. Ensure the replacement variant meets the same safety certification requirements for the specific application environment.
