Nexperia USA Inc. BAS70-06,215

Overview

BAS70-06,215 from Nexperia is a general-purpose dual Schottky diode in SOT23 package with common-anode configuration, 70 V reverse voltage rating, 70 mA forward current capability, and 410 mV typical forward voltage at 1 mA - used for ultra high-speed switching and voltage clamping in compact DC-DC converter feedback paths and signal line protection circuits.

For engineers reviewing the BAS70-06,215 datasheet, BAS70-06,215 pinout, BAS70-06,215 application, or BAS70-06,215 equivalent, key selection criteria include common-anode dual topology, low 2 pF capacitance at 0 V, sub-1 µA leakage at 50 V, thermal resistance of 500 K/W, and compatibility with reflow soldering on FR4 PCBs.

Technical Context

The BAS70-06,215 integrates two independent Schottky diodes sharing a single anode terminal (Pin 3), enabling compact dual-path clamping or steering without discrete pairing. Its junction temperature rating of 150 °C and ambient operating range from −65 °C to 150 °C support industrial and extended-temperature designs.

With 100 nA typical reverse current at 50 V and only 10 µA at VR = 70 V, it delivers stable leakage performance across temperature. Its 2 pF capacitance at 0 V and 1 MHz ensures minimal signal distortion in RF detector and high-frequency clamp applications.

FAQ

Is BAS70-06,215 suitable for automotive applications?

No. The BAS70-06,215 is explicitly marked as non-automotive qualified in its revision history. It lacks AEC-Q101 qualification, has no automotive-grade screening, and Nexperia directs users to designated -Q variants for automotive use. Industrial and commercial applications within −65 °C to 150 °C ambient are supported.

What is the meaning of the '215' suffix in BAS70-06,215?

The '215' denotes Nexperia's internal package variant code indicating tape-and-reel packaging in 3,000-unit reels with standard SOT23 orientation and moisture sensitivity level (MSL) 1. It does not indicate parameter deviation - electrical specs match the base BAS70-06 type.

Can BAS70-06,215 replace BAT54C in a common-cathode design?

No - BAS70-06,215 uses a common-anode configuration (Pin 3 = anode), while BAT54C uses common-cathode (Pin 1 = cathode). Direct substitution would invert polarity and cause circuit malfunction. Layout and schematic must be revised to accommodate the opposite terminal arrangement.

How does thermal resistance affect real-world power dissipation?

With Rth(j-a) = 500 K/W, dissipating 100 mW raises junction temperature by 50 K above ambient. At Tamb = 85 °C, Tj reaches 135 °C - within the 150 °C limit but leaving 15 K margin. Derating is advised above 70 °C ambient for sustained operation.
