60A per leg, 105 ns trr — the switching-loss tradeoff in a bolted-down package
The STTH120L06TV1: The 105 ns reverse recovery time places it in the fast-recovery class (≤500 ns, >200 mA), which means the stored charge clears quickly enough for switching frequencies in the tens of kilohertz without excessive turn-off loss. The 600 V DC reverse voltage rating and 50 µA leakage at that voltage are typical for a 600 V class ultrafast diode.
Two independent diodes in one module — layout simplification vs schematic verification
The diode configuration is listed as 2 Independent, meaning the module contains two separate diode die with no internal common-cathode or common-anode connection. This simplifies the bill of materials and PCB layout compared to two discrete ISOTOP parts, but the buyer must verify the internal pinout against the circuit schematic — the evidence does not state whether the cathodes or anodes share a common terminal. The ISOTOP package (also branded ISOTOP®) is a standard chassis-mount footprint with screw terminals and a large metal tab. The same footprint is shared across the STTH120 family, so a board or panel designed for the 1000 V STTH12010TV1 accepts this 600 V variant mechanically without rewiring.
