TLP184(GR,SE

Overview

The TLP184(GR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared emitting diode and an NPN phototransistor in a compact SO-6 package. The device provides an isolation voltage of 3750 Vrms. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 80 V and a continuous collector current (Ic) of 50 mA. The typical forward voltage (Vf) is 1.25 V with a maximum DC forward current (If) of 50 mA. The current transfer ratio ranges from 100% to 300% at If=5mA. Operating temperatures span from -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical transmission.
• Features a compact surface-mount SO-6 package designed for space-constrained applications.
• Supports both AC and DC input signal types for versatile interface compatibility.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits
• Electrical insulation between systems and subsystems

Procurement Notes

Verify the specific suffix 'GR' against official Toshiba documentation to confirm lead wire material or plating specifications, as suffixes often denote manufacturing variations rather than functional changes. Ensure the ordering code matches the required tape and reel or tube packaging format. Confirm RoHS compliance status through the latest product change notifications or datasheet revision history before finalizing procurement.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed capabilities. The 80V output voltage rating suits low-voltage digital interfaces. Consider the 3750 Vrms isolation rating for safety standards compliance. Evaluate the 50mA output current capability against load requirements. Verify that the SO-6 footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the TLP184 family of transistor output optocouplers. Variants within this series share similar core electrical characteristics but differ in packaging formats, such as standard tubes versus tape and reel options, and specific lead material compositions indicated by suffix codes like GB, GR, or TPR. The family is designed for general-purpose isolation tasks.

Replacement Considerations

Direct substitutes may include other single-channel transistor output optocouplers with comparable 3750 Vrms isolation and 80V Vceo ratings. Verify pinout compatibility and package dimensions (SO-6) to ensure mechanical fit. Check if alternative parts meet the same current transfer ratio and operating temperature range specifications.
