TLP121(GR,F)

Overview

The TLP121(GR,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 electrical isolation between input and output circuits, featuring a minimum collector-emitter breakdown voltage of 80 V and a nominal current transfer ratio of 100%. It supports a maximum forward current of 50 mA and offers an insulation voltage rating of 3750 Vrms. The component operates within a temperature range of -25 °C to 85 °C.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for signal transmission
Provides high-voltage electrical isolation via a compact DIP-4 package
Features UL recognition for safety compliance in industrial applications

Applications

Office machines such as copiers and printers
Programmable controllers and AC/DC input modules
Telecommunication equipment interfaces

Procurement Notes

Verify the specific suffix (GR,F) against official Toshiba documentation to confirm lead-free status and packaging configuration. Ensure compatibility with RoHS directives if required by the target application. Confirm that the DIP-4 package dimensions match the PCB layout requirements. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a small form factor is required for isolating low-speed digital signals. The 80 V collector-emitter voltage rating suits general-purpose switching tasks. Consider the 100% CTR rank for consistent gain performance. Verify that the 3750 Vrms isolation level meets the safety standards of the system design.

Part Context

This part belongs to the TLP121 series of mini flat couplers designed for surface mount assembly. The series is characterized by its small outline package, making it suitable for space-constrained designs in consumer electronics and industrial control systems where reliable optical isolation is necessary.
