Product details
Overview
BAV70DW-7 from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, integrating two independent BAV70 diodes with 80 V peak repetitive reverse voltage, 300 mA forward current rating, and 4.0 ns reverse recovery time. It serves as signal routing or polarity protection element in compact DC-DC converter feedback paths, USB data line ESD clamping, and low-voltage logic-level translation circuits.
For engineers reviewing the BAV70DW-7 datasheet, BAV70DW-7 pinout, BAV70DW-7 application, or BAV70DW-7 equivalent, key selection criteria include reverse recovery time under 5 ns, dual-diode integration for space-constrained PCB layouts, leakage current below 50 µA at 75 V, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
The BAV70DW-7 implements two independent silicon planar epitaxial switching diodes in a single 6-pin SOT363 package, sharing no internal connection between anodes or cathodes. Each diode exhibits low forward voltage (≤0.855 V @ 10 mA) and tightly controlled reverse breakdown (75–80 V), enabling precise voltage clamping in bidirectional signal lines.
Its 1.5 pF junction capacitance at 0 V and 4.0 ns reverse recovery time support operation up to ~100 MHz in high-frequency switching applications. Thermal resistance of 70 °C/W (junction-to-solder point) allows stable performance under pulsed 450 mA peak forward current without external heatsinking on standard FR-4 boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|
Use Scenario: Clamping transient overvoltage on D+ and D− lines during hot-plug events or ESD discharge. IC Role / Device Role / Timing Role: Dual-diode array provides bidirectional low-capacitance clamping without signal distortion. Use Value: 1.5 pF capacitance avoids signal rise-time degradation; 4.0 ns recovery prevents latch-up during fast transients. | Use Scenario: Isolating feedback voltage divider from optocoupler input in isolated flyback converters. IC Role / Device Role / Timing Role: High-speed switching diode blocks reverse current while passing regulated feedback pulses. Use Value: 80 V VR withstands reflected spikes; 300 mA IF supports robust startup sequencing. |
| Logic-Level Translation | Low-Voltage Sensor Interface |
Use Scenario: Bidirectional level shifting between 3.3 V microcontroller GPIO and 5 V peripheral I/O. IC Role / Device Role / Timing Role: Dual diode array enables passive translation using pull-up resistors on both sides. Use Value: Matched VF (≤0.855 V @ 10 mA) ensures consistent threshold across both channels. | Use Scenario: Protecting ADC inputs from overvoltage in industrial temperature or pressure sensors. IC Role / Device Role / Timing Role: Low-leakage diode limits fault current while preserving DC accuracy. Use Value: 2.5 µA IR at 75 V prevents offset drift in 1 MΩ input impedance front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7-F | Higher VR = 100 V, identical tRR = 4 ns, same SOT363 package | Better suited for 48 V systems with higher surge margin; slightly higher VF (0.88 V @ 10 mA) | Select when >80 V reverse standoff is required; verify VF impact on low-voltage logic thresholds |
| MMBD7000-7-F | Same VR = 80 V, but tRR = 6 ns, lower IF = 200 mA, SOT23-6 package | Larger footprint, slower switching - acceptable only where <10 MHz operation suffices | Choose only if SOT363 is unavailable; avoid in USB or high-frequency feedback paths |
Compared with BAV99DW-7-F and MMBD7000-7-F, the BAV70DW-7 offers optimal balance of 80 V standoff, 4 ns speed, and minimal 2.2 × 2.1 mm area-making it preferred for space-constrained 24–48 V industrial interfaces requiring sub-5 ns timing fidelity.

FAQ
What is the maximum operating temperature for BAV70DW-7?
The BAV70DW-7 has an operating junction temperature range of –55°C to +150°C. Its thermal resistance junction-to-solder point is 70°C/W, allowing reliable operation at full 300 mA forward current up to +125°C ambient when mounted per Diodes' recommended pad layout on FR-4 PCB.
Can BAV70DW-7 be used in automotive applications?
The BAV70DW-7 is not AEC-Q101 qualified. While it meets RoHS 3 and halogen-free requirements, Diodes specifies that automotive-grade versions require explicit qualification (e.g., PPAP, IATF 16949 manufacturing) - users must contact Diodes directly for AEC-compliant variants like BAV70DWQ-7-F.
How does the NC pins (3 and 6) affect PCB layout?
Pins 3 and 6 are unconnected internally and may be left floating, tied to ground, or routed as guard traces. Grounding them improves EMI immunity in noise-sensitive analog sections; leaving them unconnected simplifies routing in dense digital layouts - neither choice affects electrical performance.
Is BAV70DW-7 compatible with lead-free reflow soldering?
Yes - the BAV70DW-7 uses matte tin-plated alloy 42 leadframe and conforms to J-STD-020 moisture sensitivity Level 1. It supports standard Pb-free reflow profiles with peak temperatures up to 260°C and is rated for unlimited floor life when stored per JEDEC standards.
