TLP185(GRH-TR,SE

Overview

The TLP185(GRH-TR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a phototransistor output with a collector-emitter voltage of 80V and a maximum collector current of 50mA. The device provides an isolation voltage of 3750Vrms and operates within a temperature range of -55°C to +110°C. The current transfer ratio ranges from 150% to 300% at a forward current of 5mA. Typical switching times are 2µs for rise time and 3µs for fall time. It is housed in a compact 6-SOP surface-mount package.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Delivers fast switching response suitable for digital signal transmission
Ensures reliable operation across a wide industrial temperature range

Applications

Industrial control system I/O interface isolation
Feedback loop isolation in switch-mode power supplies
Microcontroller interface isolation for motor or relay control
Ground loop noise elimination in communication equipment

Procurement Notes

Verify the specific suffix TR against official Toshiba documentation to confirm tape-and-reel packaging configuration. Confirm RoHS compliance status through the manufacturer's latest environmental reports. Ensure the component matches the required current transfer ratio grade for the intended application circuit design.

Selection Notes

Select this component when high isolation voltage and moderate speed are required. Consider the 80V collector-emitter rating for load compatibility. Verify that the 50mA output current capability meets the downstream circuit requirements. Check thermal dissipation limits for high-temperature environments.

Part Context

This part belongs to the TLP185 series of transistor output optocouplers. The series is designed for general-purpose isolation applications. The GRH variant typically indicates a specific current transfer ratio bin. The TR suffix denotes reel packaging for automated assembly processes.
