The DO-214AA (SMB) package dissipates that through the copper pad on the PCB — the junction is rated to 175 °C, so a 2 W dissipation at 25 °C ambient requires a thermal resistance below 75 °C/W from junction to ambient. That means a generous cathode pad area and, for sustained high-current operation, a double-sided board with thermal vias. ## Reverse leakage and blocking voltage margin Maximum reverse leakage is 3 µA at the rated 200 V reverse voltage. For a 48 V bus rail the margin is 4×, so leakage stays below 1 µA at operating voltage — negligible for the bias budget. The 200 V rating also covers 100 V and 120 V bus rails with comfortable headroom. The base product number is STTH2, which covers the whole family; the 'U' suffix indicates the SMB package variant.","metaTitle":"STTH2R02U 200 V 2 A Fast Recovery Diode, 30 ns trr, SMB","metaDescription":"STMicroelectronics STTH2R02U: 200 V, 2 A fast recovery rectifier, 30 ns trr, 1 V Vf at 2 A, DO-214AA (SMB).
