A monolithic zero crossing triac driver is provided that includes a resistor network (21,22,21 min ,22 min ) coupled between two AC terminals (13,14) which provides a leakage current to the gate of a shunting field effect transistor (16), thereby ensuring the shunting transistor (16) is fully turned on when there is an AC voltage on the terminals (13,14), regardless of whether or not a light signal is applied to the circuit. The resistor network (21,22,21 min ,22 min ) is formed on the surface of the monolithic triac driver by depositing a high resistivity film over metal interconnections which are formed on the surface of the triac driver.
