Its 125 ns reverse recovery time (trr) is the headline number — fast enough to keep switching losses manageable in continuous-conduction-mode PFC stages and hard-switched SMPS output rectifiers running at 50–100 kHz. At 60 A average forward current and a 2.25 V forward drop at that current, the junction temperature rating of 175°C gives thermal headroom, but you will still need a proper heatsink — the DO-247 tab is designed for one. ## Mounting and field-service angle Through-hole DO-247 with straight leads — no hot-air station needed, just a soldering iron and a desoldering pump. If you are swapping this in a power supply on site, the orientation is obvious: the metal tab is the anode, the cathode is the centre lead. The package is standard enough that a replacement from the field kit will fit without bending leads. Just watch the heatsink — the mounting hole pattern is the same as TO-247, so the thermal interface is straightforward. ## Lifecycle — still an active line The base product number STTH6012 covers the whole family, so if you need a different package variant later, the design can migrate within the same silicon.","metaTitle":"STTH6012W Fast Recovery Diode, 1200V 60A DO-247","metaDescription":"STTH6012W 1200V 60A fast recovery diode, trr 125 ns, DO-247 through-hole.
