The copper pad area under the cathode tab sets the thermal resistance — for 1 A continuous, a 0.5 in² pad on 1 oz copper keeps the junction below 125 °C. Polarity is clear from the band, and the part lifts cleanly with hot air at 300 °C for 10 seconds without cooking the board. This diode is in standard production and can be specified into a new BOM without obsolescence risk.","metaTitle":"STTH102A 200V 1A Fast Recovery Diode, 20 ns trr, SMA","metaDescription":"STTH102A: 200V 1A fast recovery rectifier, 20 ns trr, DO-214AC SMA.
