Product details

The 1.5 pF junction capacitance at 0 V keeps signal edges clean in high-speed switching or RF detector circuits, while the 0.1 µA reverse leakage at 50 V ensures minimal quiescent drain in always-on modules.

AEC-Q101 grade — qualification scope

Active lifecycle status confirms no end-of-life or last-time-buy notice is in effect, so the part is available for ongoing production builds without a forced redesign.

Supplied in the PG-SOT23-3-3 package (TO-236-3 / SC-59 / SOT-23-3 footprint). The three-pin SOT-23 lands on a standard 0.95 mm pitch layout shared across the BAS70 family, making it a drop-in for existing Schottky footprints on automotive PCBs.

Frequently asked questions

Is BAS70B5003 AEC-Q101 certified?

Yes, the series is listed as Automotive, AEC-Q101.

What is the closest pin-compatible alternative to BAS70B5003?

The BAS70 family shares the same SOT-23-3 footprint and similar 70 V / 70 mA ratings. The BAS70-04 and BAS70-05 are dual-diode variants in the same package, but for a single-diode pin-compatible drop-in, the standard BAS70 (non-automotive grade) is the closest functional match — though it lacks AEC-Q101 qualification.
