Its 70 A (50 Hz) and 73 A (60 Hz) non-repetitive surge current rating means it can handle the inrush from a cold filament or capacitive load without failing — a key spec for relay replacement or solid-state switching where the load starts at zero impedance. ## DPAK footprint and thermal management The package accepts Tape & Reel (TR) or Cut Tape (CT) options, so it fits both high-volume pick-and-place lines and small-batch bench builds. ## Gate drive and temperature range The hold current of 40 mA ensures the SCR latches on once triggered and stays conducting until the load current drops below that threshold — typical for AC phase control where the current crosses zero each half-cycle. ## Active lifecycle and compliance It is ROHS3 compliant, meeting the latest EU restriction on hazardous substances — no lead, mercury, cadmium, or phthalates in the package.","metaTitle":"STMicroelectronics TN815-600B-TR SCR, 600V 8A DPAK","metaDescription":"STMicroelectronics TN815-600B-TR standard recovery SCR, 600 V off-state, 8 A RMS on-state, 70/73 A surge, DPAK surface mount, -40°C to 125°C, ROHS3 compliant","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","SCR Type":"Standard Recovery","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","lifecycle_stage":"eol_hot","Voltage - Off State":"600 V","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"DPAK","Current - Hold (Ih) (Max)":"40 mA","Current - Off State (Max)":"5 µA","Voltage - On State (Vtm) (Max)":"1.6 V","Current - Gate Trigger (Igt) (Max)":"15 mA","Current - On State (It (AV)) (Max)":"5 A","Voltage - Gate Trigger (Vgt) (Max)":"1.3 V","Current - On State (It (RMS)) (Max)":"8 A","Current - Non Rep.
