Its 85 ns reverse recovery time keeps turn-off losses low enough that the D²PAK package can handle 20 A without oversized heatsinking, provided the PCB tab is soldered to a copper island. ## 85 ns trr — switching loss and snubber budget At 85 ns trr, this diode recovers faster than standard 200–500 ns ultrafast parts. The recovery charge is low enough that a simple RC snubber across the diode usually contains the ringing. ## D²PAK tab-soldered thermal path The D²PAK (TO-263) package delivers the 20 A rating only when the exposed tab is soldered to a PCB copper area. Without that thermal mass, the junction climbs past 175 °C at full load. ST lists the STTH15L06G-TR as Active.","metaTitle":"ST STTH15L06G-TR Fast Recovery Diode, 20 A, 600 V, 85 ns trr","metaDescription":"STTH15L06G-TR: 20 A average, 600 V fast recovery diode, 85 ns trr, 175 °C Tj max, D²PAK.
