Package and board-fit — TO-263AB (D²PAK)
The VS-E5TH2106S2LHM3 ships in the TO-263AB (D²PAK) surface-mount package, a three-lead tabbed outline with the exposed copper tab on the bottom for thermal transfer to the PCB. The tab is the anode or cathode connection depending on the internal die orientation — the footprint copper area under the tab sets the junction-to-board thermal resistance, so the board layout directly determines the current derating at elevated ambient. Rated for a junction temperature range of -55°C to 175°C, this diode can sit in an engine-bay ECU or a high-side switch on a hot chassis rail without hitting the thermal ceiling, provided the PCB copper pours the tab heat into a thermal via array.
Switching speed — 47 ns reverse recovery
The headline recovery time is 47 ns (trr), placing it in the fast-recovery class (≤500 ns, >200 mA). That 47 ns figure means the diode clears stored charge quickly when the polarity reverses — a critical parameter in a continuous-conduction boost converter or a motor-drive freewheel leg where slow recovery adds switching loss and voltage overshoot across the FET. In a 100 kHz PFC stage, the 47 ns trr keeps the reverse-recovery charge low enough that the SiC competitor is not mandatory for the efficiency target.
Automotive-grade qualification and compliance
This part belongs to Vishay's FRED Pt® G5 series and carries AEC-Q101 qualification — the automotive discrete semiconductor stress test covering temperature cycling, high-temperature reverse bias, and ESD robustness. The AEC-Q101 stamp means the die and package survive the -55°C to 175°C swing and the vibration profile of a transmission-mounted or under-hood module.
