The 35 mA hold current means the triac stays latched once triggered as long as the load current stays above that threshold. ## Package and mounting — what to check on the board The D²Pak (TO-263-3) is a surface-mount package with a large tab for thermal and electrical connection. The tab is internally connected to the MT2 terminal, so the PCB copper pour must be electrically isolated or at MT2 potential. Cut Tape is also available for prototype quantities.","metaTitle":"STMicroelectronics T1635-800G-TR Snubberless™ Triac, 800 V","metaDescription":"STMicroelectronics T1635-800G-TR Snubberless™ alternistor triac, 800 V off-state, 16 A RMS on-state, D2PAK surface mount.
