Product details

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

The BAS 70-05 B5003: A dual Schottky diode with common-cathode configuration, rated for 70 V reverse voltage and 70 mA average rectified current per diode. Packaged in a standard SOT-23-3 surface-mount case. Reverse recovery time is specified at 100 ps, making this part suitable for RF detector circuits, mixer protection, and high-frequency rectification where switching losses must be minimised. Forward voltage drops to 1 V at 15 mA forward current, and reverse leakage is only 100 nA at 50 V, keeping power dissipation low in sensitive signal paths.

Obsolete — last-time-buy and surplus sourcing

Listed as obsolete by Infineon. Because production has ended, procurement relies on independent distribution and surplus inventory.

Package and reflow considerations

The SOT-23-3 package (Infineon code PG-SOT23) is a standard three-lead small-signal outline. It places cleanly with pick-and-place equipment and reflows on a standard lead-free profile without special handling. The common-cathode pair shares the centre pin as the cathode common, with the two anodes on the outer pins — a layout that simplifies PCB routing for dual-diode clamping networks.

Frequently asked questions

What is the difference between BAS70-05 and BAS70-04?

The BAS70-05 is a common-cathode dual Schottky diode pair, while the BAS70-04 is a series-connected pair. The pinout and internal configuration differ, so they are not direct replacements without board layout changes.

What is the replacement for BAS 70-05 B5003?

Infineon does not list a direct successor. The BAS70-05B5003 variant shares the same Schottky diode type, 70 V reverse rating, and SOT-23-3 package, but is offered in bulk packaging and carries AEC-Q101 qualification — a suitable alternative for production continuity.
