LIGHT IGNITION CIRCUIT
PRELIMINARY DATASHEET
Application Specific Discretes A.S.D.TM
FEATURES AND BENEFITS HIGH VOLTAGE BREAKOVER DIODE: VBO MIN = 195 or 215 V HIGH HOLDING CURRENT STRUCTURE : IH > 50 mA HIGH PEAK CURRENT PULSE CAPABILITY: ITRM = 50 A DIRECT OPERATION ON 220/240 VAC MAINS CIRCUITS. DESCRIPTION The LIC01 is a high performance planar diffused technology device suitable for high surge current operationin rugged environmental conditions. When the voltage across the device reaches the break over voltage, it decreases from the off state to the low voltage on-state. When the current through the circuit drops below the holding current IH , the device comes back to the off state. LIC01 has been especially designed for high voltage pulse generation circuits such as light ignitors for : . High pressure sodium lamp . Lamp flashing circuit . Metal Halid lamp

TYPICAL APPLICATION
BALLAST
When the peak voltage across C1 reaches the break over voltage VBO of the LIC01, this device turns on and produces a pulse of current through the primary of the transformer. In turns, the transformer generates high voltage pulses across the lamp.
