Overview
The TLP184(GB-TPR,E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED coupled to a phototransistor within a 6-SOP surface-mount package. The device provides high isolation voltage of 3750Vrms, supporting AC or DC input signals. Key electrical parameters include a collector-emitter voltage of 80V, a maximum forward current of 50mA, and a typical forward voltage of 1.25V. The unit operates across a temperature range of -55°C to 110°C with a CTR range of 50% to 600% at 5mA input.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and phototransistor configuration.
- Supports both AC and DC input signal types for versatile interface applications.
- Offers high insulation voltage capability suitable for noise-immune signal transmission.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic gates
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'E' against official Toshiba documentation to confirm compliance status and lead time requirements. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance details directly from the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a single-channel isolation solution with a compact 6-SOP footprint is required. Consider the 80V output voltage rating and 50mA collector current limits for load compatibility. Evaluate the 3750Vrms isolation rating against system safety standards. Compare propagation delays if high-speed switching is necessary for the target application design.
Part Context
This device belongs to the TLP184 family of transistor output optocouplers from Toshiba. Variants within this series share similar core electrical characteristics but differ in packaging options such as tube or tape-and-reel configurations. The GB designation typically indicates specific internal material or processing variations compared to standard versions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Toshiba's official replacement guide or contact technical support for verified alternatives.
