Dual Schottky in a thermally efficient package
The RB088T-30NZC9 is a 30V, 10A per diode Schottky rectifier configured as a common cathode pair in the TO-220FN Full Pack package. The isolated tab eliminates the need for a mica insulator or thermal pad against the heatsink, simplifying assembly and improving thermal transfer to the case.
Forward drop and leakage trade-off
Maximum forward voltage is 720 mV at 5 A per diode, which keeps conduction losses manageable in a 10 A average rectified load. Reverse leakage is specified at 3 µA at 30 V — the 'super low IR' designation in the description means this diode suits circuits where standby power or leakage at elevated temperature is a concern. The fast recovery speed (≤500 ns, >200 mA) qualifies it for switching frequencies above line frequency, though as a Schottky the recovery is majority-carrier and inherently fast — the spec confirms it for applications like output rectification in switch-mode supplies up to a few hundred kHz.
