Rated for 800 V off-state voltage. TO-220FPAB full-pack — the tab is fully isolated, no insulating washer needed. Mount with a single M3 screw and a dab of thermal compound. ROHS3 compliant with no exemptions; no REACH or conflict-minerals concern for EU shipments. The Snubberless series is a mature, stable product line; PCN frequency is low.","metaTitle":"ST T1635T-8FP Snubberless Triac, 16A 800V TO-220FPAB","metaDescription":"STMicroelectronics T1635T-8FP Snubberless Alternistor triac, 16A RMS, 800V off-state, TO-220FPAB.
