TLP3073(F

Triac, SCR Output Optoisolators Overview

The TLP3073(F) is a triac output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared LED with a photo-triac for electrical isolation. The device features an 800V blocking voltage and provides 5000Vrms insulation strength between input and output circuits. It operates with a minimum gate trigger current of 5mA and requires a holding current of 3V to maintain conduction. The component is available in tube packaging, specifically the SO-6L or DIP-6 configurations depending on the suffix variant.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation via integrated infrared LED and photo-triac architecture
