TLP121(GRH-TPR,F)

Overview

The TLP121(GRH-TPR,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 features a minimum collector-emitter breakdown voltage of 80 V and a maximum forward current of 50 mA. The GRH rank specifies a minimum current transfer ratio of 100%. It provides a minimum isolation voltage of 3750 Vrms and operates within a temperature range of -25 °C to 85 °C.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for electrical isolation
High current transfer ratio performance in the GRH rank configuration
Mini flat DIP-4 plastic package designed for surface mount assembly

Applications

Office machines
Programmable controllers
AC/DC input modules
Telecommunication equipment

Procurement Notes

Verify the specific suffix (GRH-TPR,F) against official Toshiba documentation to confirm the exact binning, packaging format, and compliance status. Ensure the component matches the required current transfer ratio rank and insulation voltage specifications for the target design. Confirm lead times and availability directly with authorized distributors as supply conditions vary.

Selection Notes

Select this component when high current transfer ratio accuracy is required for signal transmission applications. The GRH rank ensures a minimum CTR of 100%, suitable for precise switching tasks. The mini flat package facilitates automated surface mount placement. Verify that the 80 V collector-emitter voltage rating meets the load requirements of the isolated circuit.

Part Context

This part belongs to the TLP121 series of mini flat couplers from Toshiba. The series is characterized by small outline packages suitable for surface mount technology. The TLP121 family is widely used in industrial and consumer electronics requiring compact isolation solutions between control circuits and power stages.

Replacement Considerations

Check for direct substitutes such as other TLP121 variants with different suffixes or equivalent transistor output optocouplers from other manufacturers. Ensure pinout compatibility and matching electrical parameters like isolation voltage and CTR before substitution.
