It is qualified to AEC-Q101, making it suitable for automotive under-hood and chassis-domain environments where reliability screening is required. Each diode is rated for 70 mA average rectified current with a 70 V maximum reverse voltage, placing it firmly in the small-signal switching class — not a power rectifier. The 70 V Vr(max) gives enough headroom for 12 V automotive rails (including load-dump transients up to 40 V) without avalanche stress. The 70 mA per-diode rating means this part is sized for signal-level clamping, logic-level translation, or low-current OR-ing — not for bulk supply rectification or high-side load switching. If your design needs more than 70 mA continuous per channel, you need a larger Schottky. ## Forward drop and leakage — the signal-path specs Forward voltage is 1 V maximum at 15 mA — typical for a small-signal Schottky, low enough for 3.3 V logic-level clamping but not as low as a 0.3 V power Schottky. Reverse leakage is 100 nA at 50 V, which is tight enough for high-impedance analog inputs or battery-powered wake-up circuits. Both specs matter when the diode sits on a sensor line or a CAN bus protection clamp. ## Package and footprint — SOT-23-3 common-anode layout The BAS70-06B5003 comes in a standard SOT-23-3 package (Infineon code PG-SOT23-3-3). The 150°C junction temperature rating supports under-hood ambient temperatures when derated appropriately.","metaTitle":"Infineon BAS70-06B5003 Schottky Diode, 70 V, 70 mA, AEC-Q101","metaDescription":"Infineon BAS70-06B5003 dual common-anode Schottky diode. 70 V reverse voltage, 70 mA per diode, 1 V Vf at 15 mA.
