Product details

The Infineon BAS 70-04 B5003 is a dual Schottky diode in a series configuration, housed in a standard SOT-23-3 (PG-SOT23) surface-mount package. It is rated for a DC reverse voltage of 70 V and an average rectified current of 70 mA per diode, with a forward voltage drop of 1 V at 15 mA. The reverse recovery time is specified at 100 ps, making it suitable for high-speed switching and RF clamping applications where fast turn-off is needed. Typical uses include protection clamping in mixed-signal circuits, high-speed switching power supplies, and signal steering in telecom or instrumentation front ends.

Obsolete — sourcing reality for sustainment programs

The BAS 70-04 B5003 carries an obsolete lifecycle status.

The 100 ps reverse recovery time allows the diode to switch off faster than most standard Schottky diodes, which matters in high-frequency rectification or snubber circuits where stored charge causes losses.

Frequently asked questions

Is BAS 70-04 B5003 obsolete and what is its replacement?

Yes, the BAS 70-04 B5003 is listed as obsolete. No official replacement order code is provided in the product record. For a form-fit-function substitute, evaluate the standard BAS 70-04 (without the B5003 suffix) in the same SOT-23 package — it shares the same die and electrical ratings, though the tape-and-reel suffix may differ. Confirm pin compatibility and electrical specs against your design before substituting.

Where can I buy BAS 70-04 B5003 available via RFQ confirmation?

No stock count or price is published here.

What are the electrical specifications of BAS 70-04 B5003?

It is a dual series Schottky diode rated for 70 V DC reverse voltage, 70 mA average rectified current per diode, 1 V forward drop at 15 mA, 100 nA reverse leakage at 50 V, and a reverse recovery time of 100 ps. Operating junction temperature is 150 °C maximum.
