The 100 ns trr (reverse recovery time) keeps the turn-off loss low enough to run switching frequencies in the 50–150 kHz range without thermally overrunning the junction. At 30 A forward current the forward voltage drop is 1.45 V max — that conduction loss at full load sets the heatsink requirement. ## D2PAK footprint — board-level thermal management The D2PAK (TO-263) surface-mount package has a large copper tab that is the cathode connection. The package ships in Tube form, not Tape & Reel, so if your pick-and-place line expects reel feed, confirm the tube-to-reel transfer or order a reel variant. The reverse leakage is 15 µA at 400 V — a low enough number to avoid standby-power penalties in off-line supplies.","metaTitle":"STTH30R04G 30 A 400 V Fast Recovery Diode, 100 ns trr, D2PAK","metaDescription":"STTH30R04G fast recovery diode: 30 A average, 400 V Vr, 100 ns trr, -40 to 175 °C junction.
