Dual 6 A Schottky in a TO-252 — low-leakage OR-ing or output rectifier
The RB098BM-30TL is a dual common-cathode Schottky rectifier rated 30 V reverse and 6 A average per diode. The TO-252 DPAK footprint mates with standard pad layouts and the tab carries the cathode — the common node for OR-ing or center-tap rectifier designs. ROHM markets this as a 'super low IR' part: reverse leakage is just 1.5 µA at 30 V. That matters in a battery-powered rail where the diode sits across the supply — the leakage current won't drain the cell during standby.
Forward drop and switching speed — the trade-off
Forward voltage is 720 mV at 3 A per diode — a moderate Vf for a 6 A Schottky. The speed is classified as fast recovery (≤ 500 ns, > 200 mA Io), which covers 50/60 Hz rectification and low-frequency switching. For a 100 kHz+ PFC stage you would look at a faster SiC or ultra-fast silicon diode; this part is at home in output rectification and OR-ing where the switching edges are soft. Junction temperature is rated to 150 °C, so the part has headroom in a cramped PSU or under-hood environment.
Active production, ROHS3 — no last-time-buy pressure
Sourced through independent distribution; availability and current pricing confirmed at RFQ. The TO-252 package is widely stocked, so lead times tend to be short for reasonable quantities.
