TLP121(TA-TPR,F)

Overview

The TLP121(TA-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. Key electrical parameters include a minimum collector-emitter breakdown voltage of 80 V, a typical current transfer ratio of 100%, and a maximum forward current of 50 mA. The device supports an operating temperature range from -25 °C to 85 °C and features a maximum insulation voltage of 3750 Vrms.

Feature Summary

Integrates a GaAs infrared LED with a phototransistor for signal isolation
Provides high insulation voltage capability for safety separation
Designed for surface mount assembly in compact packages

Applications

Office machines such as copiers and printers
Programmable controllers and I/O interface boards
AC/DC input modules for industrial control systems
Telecommunication equipment signal isolation

Procurement Notes

Verify the specific suffix TA-TPR,F against official Toshiba documentation to confirm pin configuration and tape-and-reel specifications. Ensure compliance with UL recognition standards (File No. E67349) if required for end-product certification. Confirm RoHS status and material declarations prior to ordering.

Selection Notes

Select this component when a low-profile surface mount solution is required for general-purpose isolation. Consider the 80 V collector-emitter voltage limit and 50 mA forward current constraints. Evaluate thermal dissipation requirements within the specified operating temperature range during circuit design.

Part Context

This part belongs to the TLP121 series of mini flat couplers designed for space-constrained applications. The series offers various ranking options for current transfer ratio and utilizes standard DIP-4 packaging to facilitate automated surface mount production processes.
