Overview
The TLP185(TPR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a surface-mount SO-6 package with four pins. The device provides an isolation voltage of 3750Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.4V, and a current transfer ratio ranging from 50% to 600%. Operating temperatures span from -55°C to 110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using a phototransistor configuration.
- Offers wide current transfer ratio variation to accommodate diverse signal transmission requirements.
- Designed for surface-mount assembly in compact electronic layouts.
Applications
- Digital I/O isolation in programmable logic controllers
- Feedback control loops in switching power supplies
- Interface isolation between microcontrollers and high-voltage components
Procurement Notes
Verify the specific suffix designation against official Toshiba documentation to confirm performance characteristics such as current transfer ratio ranges and response times. Ensure that the selected variant matches the required isolation voltage and operating temperature specifications for the target application environment.
Selection Notes
Select this component when a single-channel transistor output is required for moderate-speed signal isolation. Consider the wide CTR range and 3750Vrms isolation capability. Evaluate thermal management needs given the 110°C maximum operating temperature limit and surface-mount form factor constraints.
Part Context
This part belongs to the TLP185 series of transistor output optocouplers. The series is designed for general-purpose isolation applications requiring robust electrical separation. Variants within the series differ primarily in packaging options and specific electrical parameter tolerances defined by their suffix codes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official Toshiba cross-reference guides or distributor databases for verified compatible alternatives.
