TLP3041F(S),TLP3042F(S),TLP3043F(S) are optical couplers produced by Toshiba. The product consists of a zero voltage crossing turn-on photo-triac and a gallium arsenide infrared emitting diode. The product has the characteristics of high peak off-state voltage, high trigger LED current, high on-state current and high insulation voltage.
The Toshiba TLP3041F(S), TLP3042F(S) and TLP3043F(S) are GaAs infrared LED phototriac optocouplers packaged in a six‑lead DIP. They provide zero‑voltage‑crossing turn‑on and include detailed electrical parameters such as peak off‑state voltage, trigger LED current, on‑state current and isolation voltage.
The devices are approved to several safety standards (UL1577, VDE DIN EN60747‑5‑2, EN60065, EN60950) and have mechanical ratings for creepage, clearance and insulation thickness. Usage restrictions are noted, advising against deployment in safety‑critical or high‑reliability applications such as aerospace, medical or traffic control equipment.
