Product details

70 V, 70 mA series Schottky pair in SOT-23-3

The BAS70-04FILM is a series-connected Schottky diode array from STMicroelectronics, rated for 70 V reverse voltage and 70 mA average rectified current per diode. Forward voltage is 1 V maximum at 15 mA, with reverse leakage of 10 µA at 70 V. It comes in a standard SOT-23-3 surface-mount package (TO-236-3 / SC-59), suited for automated assembly on low-profile boards.

Sourcing and cross-reference note

The closest functional second-source is the BAS70-04WFILM, which shares the same SOT-23-3 package, 70 V / 70 mA ratings, and series diode configuration — a drop-in alternative for BOM qualification.

Frequently asked questions

What is the closest functional second-source for BAS70-04FILM?

The BAS70-04WFILM is a drop-in functional equivalent — same SOT-23-3 package, same 70 V / 70 mA ratings, same series diode configuration. It can be qualified as a second source without a board spin.

Who supplies BAS70-04FILM and how is it quoted for volume purchases?

Pricing and lead time are confirmed at RFQ against the specific BOM quantity.
