Product details

40 V, 6 A common-cathode Schottky — what the ratings mean on the bench

The RB098BM-40TL: That 6 A figure is the continuous DC rating per side — in a typical OR-ing or freewheeling application, each diode handles its own load without sharing the other's current, so the total package can pass 12 A if the two channels are paralleled (with matching forward drops). The forward drop is 770 mV at 3 A — that's the conduction loss floor. At 6 A the drop will be higher, but the super-low reverse leakage of 1.5 µA at 40 V means it won't cook itself in a high-temperature standby circuit.

Active production and compliance

That means it's still a valid BOM line for new designs and doesn't carry a last-time-buy clock.

Frequently asked questions

What is the closest pin-compatible alternative to RB098BM-40TL?

The part is a standard TO-252 common-cathode Schottky — several manufacturers offer similar 40 V, 6 A dual diodes in the same package, but pinout and thermal pad layout should be verified against the target board before substituting.
