TLP121(GRH-TPL,F)

Overview

The TLP121(GRH-TPL,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 compact DIP-4 plastic package. The device provides an isolation voltage of 3750 Vrms and a minimum collector-emitter breakdown voltage of 80 V. It supports a maximum forward current of 50 mA and operates within a temperature range of -25 °C to 85 °C.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for efficient optical coupling
Provides high electrical isolation capability suitable for signal transmission between circuits
Designed for surface mount assembly using a small outline DIP-4 package

Applications

Office machines
Programmable controllers
AC/DC input modules
Telecommunication equipment

Procurement Notes

Verify the specific suffix (GRH-TPL,F) against official Toshiba documentation to confirm lead-free status and RoHS compliance, as standard TLP121 variants may differ. Confirm UL recognition file numbers and insulation ratings match system requirements before procurement.

Selection Notes

Select this component when a low-profile surface mount transistor output optocoupler is required for general-purpose signal isolation. Ensure the 80 V collector-emitter voltage rating meets the load requirements and that the DIP-4 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the TLP121 series of mini flat couplers designed for space-constrained applications. The series is characterized by its small outline package and reliability in industrial and consumer electronics environments requiring galvanic isolation.

Replacement Considerations

Consult official Toshiba substitution guides for verified equivalents. Generic replacements must match the DIP-4 package, transistor output type, and isolation voltage specifications.
