TLP121(GRH-TP,F)

Overview

The TLP121(GRH-TP,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a phototransistor in a mini flat DIP-4 plastic package. The device provides high isolation voltage of 3750 Vrms minimum and supports a collector-emitter breakdown voltage of at least 80 V. It features a current transfer ratio of 100% for the GRH rank and operates within a temperature range of -25°C to 85°C.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for optical signal transmission
Provides high electrical isolation between input and output circuits
Designed for surface mount assembly in compact form factors

Applications

Office machines
Programmable controllers
AC/DC input modules
Telecommunication equipment

Procurement Notes

Verify the specific suffix (GRH-TP,F) against official Toshiba documentation to confirm exact binning, tape-and-reel packaging specifications, and RoHS compliance status. Ensure the component matches the required current transfer ratio rank and operating temperature range for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a small outline transistor-output optocoupler is required for digital signal isolation. Consider the 80 V collector-emitter voltage rating and the specific CTR rank for interface compatibility. Evaluate the DIP-4 package constraints against available PCB space and mounting requirements compared to alternative optocoupler families.

Part Context

This part belongs to the TLP121 series of mini flat couplers from Toshiba. The series is characterized by its small outline package suitable for automated surface mount assembly. It serves as a standard solution for isolating low-voltage control signals from higher-voltage loads in industrial and consumer electronics applications.

Replacement Considerations

Consult official Toshiba substitution guides for verified equivalents. Generic replacements may differ in isolation voltage, CTR, or package dimensions. Verify pinout compatibility and electrical characteristics before integrating substitute parts into existing designs.
