TLP184(GB,SE

Overview

The TLP184(GB,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared emitting diode optically coupled to a phototransistor within a compact 6-SOP surface-mount package. The device provides high isolation voltage of 3750Vrms between input and output circuits. Key electrical parameters include a collector-emitter saturation voltage of 300mV maximum, a forward current of 50mA maximum, and a collector output current of 50mA per channel. It operates reliably across a wide temperature range from -55°C to 110°C.

Feature Summary

• Provides galvanic isolation via optical coupling between input LED and output phototransistor
• Utilizes a compact 6-SOP surface-mount package for efficient PCB layout
• Ensures high dielectric strength with 3750Vrms isolation capability
• Supports AC or DC input signal transmission

Applications

• Signal isolation in industrial control systems
• Interface circuits for microprocessors and logic devices
• Power supply feedback loops requiring electrical isolation
• Communication interface isolation for data transmission

Procurement Notes

Verify the specific suffix (GB,SE) against the manufacturer's latest datasheet to confirm packaging type and compliance status. Ensure the ordering code matches the required tape and reel or tube configuration. Cross-reference RoHS and REACH compliance declarations with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel transistor output isolator is required with moderate speed characteristics. Consider the 6-SOP footprint constraints and the 3750Vrms isolation rating relative to system safety standards. Evaluate the CTR specifications at the intended operating current to ensure adequate signal transfer margins for the application load.

Part Context

This part belongs to the TLP184 family of transistor output optocouplers. Variants such as TLP184(TPL,SE and TLP184(V4GBTR,SE share similar core electrical characteristics but differ in packaging formats like tape and reel versus tube. The family is designed for general-purpose isolation applications requiring reliable performance in compact electronic designs.

Replacement Considerations

Direct substitutes include other TLP184 variants with matching pinouts and electrical ratings. Verify that alternative parts maintain the same 6-SOP package dimensions and isolation voltage levels. Ensure compatibility with existing PCB footprints and thermal management requirements during substitution.
