With a forward voltage of 370 mV typical at 1 mA, it keeps conduction losses minimal in battery-powered or low-voltage rails where every millivolt of headroom counts. Reverse leakage is 500 nA at 30 V — low enough for energy-harvesting or wake-up circuits that cannot tolerate bleed current draining the storage cap. ## SC-89 footprint — what it demands from the board Housed in the SC-89 (SOT-490) package with supplier device package designation EMD3F, this is a three-pin SMD footprint — the two diodes share a common cathode, with the anodes on pins 1 and 2. The junction temperature rating of 125 °C gives thermal margin for reflow soldering and moderate ambient heat, but the 30 mA average current means the self-heating is negligible in normal operation — the limiting factor is the ambient, not the die. Classified as Small Signal =< 200 mA (Io), Any Speed — the switching speed is not explicitly specified, but Schottky construction inherently recovers faster than a PN-junction at these current levels; expect sub-nanosecond reverse recovery. ## Active production, ROHS3 — straight-line procurement ROHS3 compliant per the manufacturer declaration, with no exemptions or transition-lot concerns for EU or California markets.","metaTitle":"ROHM RB706WM-40TL Schottky Diode, 40V, 30mA, SC-89","metaDescription":"RB706WM-40TL Schottky diode from ROHM: 40V Vr, 30mA Io, 370mV Vf at 1mA.
