Its 40 ns reverse recovery time places it in the fast-recovery class for continuous-current switching above 200 mA, making it a fit for power-factor-correction boost stages, flyback snubbers, and output rectification in medium-power SMPS designs. ## Switching loss and thermal budget A 40 ns trr at 5 A forward current means the diode recovers before the MOSFET body diode in a hard-switching boost converter, reducing the reverse-recovery charge that the switch must absorb. The 2.9 V forward drop at 5 A is the conduction-loss floor — at 5 A average, expect about 14.5 W peak dissipation before derating for junction temperature. The 175°C maximum junction rating gives headroom for high ambient or tight thermal layouts, but the DPAK's thermal resistance demands a copper pour on the drain tab to keep Tj below the limit. ## Leakage and blocking margin Reverse leakage is specified at 20 µA at 600 V — a clean number that lets you budget standby loss in a PFC stage without over-allocating heatsink area. The 600 V blocking voltage gives margin for 400 VDC bus rails with ringing; for 800 V systems or high-line surges, you would step up to a 1 kV rated part. The DPAK (TO-252-3) surface-mount package has two leads plus the exposed tab.","metaTitle":"STTH5R06B 600V 5A Ultrafast Diode, 40 ns trr, DPAK","metaDescription":"STTH5R06B ultrafast high-voltage diode: 600V, 5A, 40 ns trr, DPAK surface-mount.
