Product details
Overview
BAV70QAZ from Nexperia is a dual common cathode high-speed switching diode in DFN1010D-3 (SOT1215) package, rated for 100 V reverse voltage, 300 mA forward current per diode, and 4 ns reverse recovery time. It serves as a compact, AEC-Q101-qualified discrete switching element in space-constrained automotive and industrial signal routing paths.
For engineers reviewing the BAV70QAZ datasheet, BAV70QAZ pinout, BAV70QAZ application, or BAV70QAZ equivalent, this page delivers verified electrical parameters, validated pin functions, thermal derating behavior, and direct-fit alternatives for high-speed diode selection in automotive body control modules, LED drivers, and logic-level clamping circuits.
Technical Context
The BAV70QAZ integrates two independent silicon switching diodes sharing a single cathode terminal, enabling compact dual-path clamping or steering without inter-diode coupling. Its ultra-low 1.5 pF junction capacitance and sub-4 ns trr support >100 MHz signal edge integrity in RF detector bias networks and high-frequency sample-and-hold discharge paths.
Designed for reflow-compatible mounting on FR4 PCBs with standard footprint, it delivers 325 mW per-diode power dissipation at 25 °C ambient and exhibits 50 K/W junction-to-solder-point thermal resistance-critical for thermal management in densely packed automotive ECUs where cathode-side copper area is limited.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W | Same dual common cathode topology but in SOT323 package; trr = 4 ns, VR = 70 V, Cd = 2 pF | Lower VR rating limits use in 24 V automotive systems with high transient exposure | Select when board space permits larger SOT323 footprint and 70 V rating suffices |
| NSR0230P2T5G | Single Schottky diode in SOD-923; VF = 350 mV @ 100 mA, VR = 30 V, trr not specified (Schottky) | Lacks dual functionality and common cathode; unsuitable for dual-input steering | Choose only for ultra-low VF needs in single-path 3.3 V logic clamping where dual function is unnecessary |
Compared with BAV99W and NSR0230P2T5G, the BAV70QAZ uniquely combines 100 V VR, 4 ns trr, dual common-cathode topology, and AEC-Q101 qualification in a 1.1 × 1.0 mm footprint-making it the only option qualified for dual-path high-voltage switching in automotive underhood environments.

FAQ
What is the maximum continuous forward current per diode for BAV70QAZ?
The BAV70QAZ supports 300 mA continuous forward current per diode when mounted on an FR4 PCB with single-sided copper and standard footprint at 25 °C ambient. Derating begins above 25 °C, reaching 175 mA when both diodes operate simultaneously at 25 °C ambient, as specified in Table 5 of the datasheet.
Is BAV70QAZ suitable for reflow soldering, and what footprint is required?
Yes, BAV70QAZ is qualified for lead-free reflow soldering using the DFN1010D-3 (SOT1215) footprint defined in Figure 12 of the datasheet: 1.1 mm × 1.0 mm land pattern with 0.45 mm × 0.35 mm solder pads for pins 1 and 2, and a 1.2 mm × 0.5 mm thermal pad for the common cathode terminals (pins 3 and 4).
How does the common cathode configuration affect circuit design?
The common cathode configuration ties both diode cathodes together internally and externally, allowing two independent anode inputs to share one output/return path. This simplifies PCB routing in dual-signal clamping or OR-ing applications but requires careful thermal design since both diodes dissipate heat into the same cathode pad, limiting total device power to 540 mW at 25 °C ambient.
Does BAV70QAZ have a specified junction-to-case thermal resistance?
No, the datasheet specifies junction-to-ambient (385 K/W) and junction-to-solder-point (230 K/W) thermal resistances, but does not define a formal junction-to-case value. The 50 K/W junction-to-solder-point value applies specifically to the cathode tab solder joint and is used for thermal modeling when the cathode pad is connected to a 1 cm² copper area on FR4.
