TLP184(GR-TPR,SE

Overview

The TLP184(GR-TPR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED coupled to a phototransistor within a compact 6-SOP surface-mount package. The device provides high isolation voltage of 3750Vrms and supports AC or DC input signals. 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. The unit operates across a wide temperature range from -55°C to 110°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission
• Accepts both alternating current and direct current input signal types
• Delivers high-speed switching performance with typical rise and fall times of 2µs and 3µs respectively

Applications

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

Procurement Notes

Verify the specific suffix GR-TPR,SE against official Toshiba documentation to confirm RoHS compliance status and tape-and-reel packaging configuration. Ensure the selected variant matches the required current transfer ratio specifications for the target application circuit design.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required in a small surface-mount footprint. Consider the CTR range and saturation voltage limits relative to the load requirements. Verify compatibility with standard SOP-6 footprints during PCB layout planning.

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 and compliance markings. The GR-TPR,SE designation indicates specific manufacturing and packaging attributes defined by Toshiba.

Replacement Considerations

Direct replacements must match the 6-SOP package, 3750Vrms isolation rating, and transistor output type. Verify pinout compatibility and ensure equivalent switching speed and current handling capabilities before substitution.
