TLP121(TPL,F)

Overview

The TLP121(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 electrical isolation between input and output circuits, featuring a minimum collector-emitter breakdown voltage of 80 V and a maximum forward current of 50 mA. It supports an operating temperature range from -25 °C to 85 °C and offers a minimum isolation voltage of 3750 Vrms.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for signal transmission
Provides high-voltage electrical isolation between input and output sides
Designed for surface mount assembly in small outline packages

Applications

Office machines
Programmable controllers
AC/DC input modules
Telecommunication equipment

Procurement Notes

Verify the specific suffix (TPL,F) against official Toshiba documentation to confirm pinout configuration and lead material specifications. Ensure compliance with relevant safety standards such as UL recognition before integration into final designs.

Selection Notes

Select this component for applications requiring compact isolation with transistor-level output switching. Consider the 80 V collector-emitter voltage rating and 50 mA forward current limits when designing drive circuits.

Part Context

This part belongs to the TLP121 series of mini flat couplers designed for surface mount technology. It serves as a cost-effective solution for isolating low-power control signals in industrial and consumer electronics environments.
