That 30 ns trr is the interval the diode takes to sweep stored charge out of the junction and block reverse voltage — the shorter this window, the less overlap between current and voltage during turn-off, which directly cuts switching loss in a hard-switched converter or flyback clamp. Rated for 150 V reverse (Vr max) and 6 A average forward (Io), the part handles the blocking and conduction side of the switching cycle. The forward drop hits 1.76 V maximum at 18.8 A peak — that is the conduction loss floor at the surge current, not the steady-state 6 A level where Vf will be lower. ## Hermetic E-MELF — why the package matters for reliability The E-MELF (D-5B) is a hermetic ceramic barrel with metallized end caps — no plastic molding, no moisture absorption, no popcorn cracking during reflow. Surface-mount assembly on the D-5B footprint is straightforward: the barrel sits on solder pads at both ends, and the metallization wets reliably with standard SnPb or SAC solder profiles. No heat-sink tab — thermal management relies on the board copper area under each end cap. ## Active lifecycle — no LTB clock ticking The base product number is 1N6078; the US suffix denotes the D-5B surface-mount package variant. If your BOM calls the through-hole version (1N6078), the die is the same — only the package changes. Sourced to order against an RFQ through independent and authorized distribution channels.","metaTitle":"Microchip 1N6078US Fast Recovery Diode, 150V 6A D-5B","metaDescription":"1N6078US fast recovery diode, 150V 6A, 30ns trr, E-MELF package.
