It targets high-speed switching, signal clamping, and low-loss rectification in circuits where junction capacitance and forward voltage matter more than raw current capacity. ## Forward voltage and capacitance — the design-relevant specs Forward voltage is 410 mV maximum at 1 mA forward current — low enough to keep conduction loss minimal in low-current signal paths and clamping networks. Junction capacitance is 2 pF at 0 V reverse bias and 1 MHz, which preserves signal integrity in RF and high-speed digital lines where capacitive loading would otherwise round edges or shift thresholds. ## Reverse leakage and temperature headroom Reverse leakage is 200 nA at 50 V reverse bias, a typical figure for a 70 V Schottky at room temperature. The junction is rated for a maximum operating temperature of 150°C, giving thermal margin in warm enclosures or near power components — though leakage doubles roughly every 10°C above 25°C, so derate the reverse voltage if the ambient runs hot.","metaTitle":"STMicroelectronics BAR18FILM Schottky Diode, 70V 70mA","metaDescription":"Small-signal Schottky diode, 70V reverse, 70mA forward, 410 mV Vf at 1 mA, 2 pF capacitance.
