Toshiba TLP165J Data Handbook
Summary
The TLP165J is a robust mini flat optocoupler phototriac designed for signal isolation and controlling AC output in solid state relays and modules. Utilizing a Gallium Arsenide infrared LED, this component efficiently transfers low-voltage control signals to high-power AC loads. This technical guide provides essential electrical specifications, maximum ratings (up to 2500 Vrms isolation), and recommended operating guidelines needed for system integration. It is ideal for professionals designing general consumer, domestic, or industrial electronic applications needing reliable signal separation.

Frequently Asked Questions
What is the primary function of the TLP165J?
It is a small outline coupler that functions as a photo triac, optically coupled to a gallium arsenide infrared emitting diode.
What are the specified electrical ratings for isolation voltage?
The minimum insulation voltage (BV) is 2500 Vrms. The peak nonrepetitive surge current (TSM) rating is 1.2 A.
What precautions must be taken regarding GaAs components?
GaAs dust and fumes are toxic; do not break, cut, or dissolve the product with chemicals, and dispose of it according to regulations.
Under what operating conditions should the TLP165J generally be used?
It is intended for general electronics applications (e.g., industrial robotics, domestic appliances) but is not warranted for equipment requiring extraordinarily high reliability or life-critical functions.
