Introduction

AI Translation

The TLP291 consists of a phototransistor optically coupled with a GaAs infrared LED. Housed in an SO4 package, it is an extremely compact and low-profile coupler. The TLP291 guarantees a wide operating temperature range (Ta = -55 to 110°C) and high isolation voltage (3750Vrms), making it suitable for high-density SMT applications such as compact switching power supplies and programmable controllers.
