Introduction

AI Translation

The TLP291(SE consists of a phototransistor optically coupled to a GaAs infrared emitting diode. Housed in an SO4 package, it is an extremely small and thin coupler. The TLP291(SE 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.
