|TO-220AB|600 V|2 to 5 mA| |TN1205H-6G|D2PAK||| These products fit all modes of control found in applications such as overvoltage crowbar protection, motor control circuits in power tools and kitchen aids, inrush current limiting circuits, capacitive discharge ignition and voltage regulation circuits. These products are particulary adapted for use in areas where the ambient temperature is high or the ventilation low, or where an increase of power density is required. Through-hole or surface-mount packages provide performance in a limited space area. 1/10 April 2012 Doc ID 018497 Rev 4 This is information on a product in full production. _www.st.com_ **Characteristics** **TN1205H** ## **1 Characteristics** ## **Table 2.
