## **Features** - Three quadrants with logic level gate - Benefits: - Super low holding current IH = 5 mA - Optimized thermal performance with low power dissipation - Optimized turn-off commutation for lighting loads ## **Application** - Lighting: - Universal light dimmers - LED light dimmers - Heating - Overvoltage crowbar protection ## **Description** The T1605G-6I Triac in TO-220AB insulated can be used for the on/off or phase angle control function in general purpose AC switching where high commutation capability is required. Its super low holding current IH enables deep dimming for LED light dimmers without flickering nor jittering. **Product status link** T1605G-6I |**Product summary**|**Product summary**| |---|---| |**Order code**|T1605G-6I| |**Package**|TO-220AB Ins.| |**VDRM/VRRM**|600 V| |**IGT**|5 mA| |**IH**|5 mA| Package environmentally friendly ECOPACK2, RoHS (2011/65/EU) and halogen free compliant.
