Product details
Overview
BAW56WQ-7-F from Diodes Incorporated is a dual surface-mount switching diode in SOT323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time, optimized for high-speed signal routing and polarity protection in automotive infotainment and power management circuits.
For engineers reviewing the BAW56WQ-7-F datasheet, BAW56WQ-7-F pinout, BAW56WQ-7-F application, or BAW56WQ-7-F equivalent, this AEC-Q101 qualified dual diode supports fast-switching requirements in space-constrained PCB layouts with verified thermal performance (RθJA = 625 °C/W) and low-leakage operation at elevated temperatures.
Technical Context
The BAW56WQ-7-F integrates two independent silicon switching diodes in a single SOT323 package with common-cathode configuration confirmed by internal schematic and top-view marking. Its 4.0 ns trr and sub-1.0 V VF at 10 mA enable clean digital signal edge handling in level-shifting and clamp circuits.
Designed for automotive-grade reliability, it operates across –55 °C to +150 °C, maintains ≤50 µA IR at VR = 75 V and TJ = +150 °C, and delivers 2.0 pF junction capacitance at zero bias-critical for RF bypass and ESD protection staging.

Applications
| Automotive Infotainment | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Bidirectional signal clamping on LVDS or FPD-Link II video buses in head units and display modules. IC Role / Device Role / Timing Role: Dual-anode, common-cathode switching diode providing rail-to-rail transient suppression without signal inversion. Use Value: Prevents ESD-induced latch-up in SerDes ICs while maintaining <2.0 pF loading for 480 Mbps USB signaling. | Use Scenario: D+ and D– line overvoltage protection in automotive USB host ports. IC Role / Device Role / Timing Role: Independent anode paths route each data line to shared cathode tied to VBUS or ground reference. Use Value: Enables simultaneous 2-line clamping with matched VF and trr, preserving differential timing skew <100 ps. |
| Power Supply OR'ing | Logic-Level Translation Clamp |
Use Scenario: Redundant 12 V supply selection in ADAS domain controllers using ideal diode topology. IC Role / Device Role / Timing Role: Dual diode implements back-to-back forward conduction path with shared return node. Use Value: Delivers 300 mA per path with <0.86 V forward drop at 10 mA, minimizing voltage loss vs. MOSFET solutions. | Use Scenario: 3.3 V ↔ 5 V logic interface protection in microcontroller GPIO banks. IC Role / Device Role / Timing Role: Anode-to-GPIO and anode-to-VCC clamping diode pair limits voltage excursions to safe levels. Use Value: 4.0 ns trr prevents metastability during 10–50 MHz toggle rates; 2.0 pF CT avoids RC delay degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-7-F | Same SOT323 package, 70 V VRRM, 3.0 ns trr, 0.85 V VF @ 10 mA | Slightly faster switching but lower reverse voltage rating | Select when >100 MHz edge rates dominate over 75 V+ clamping needs |
| MMBD7000-7-F | SOT23 package, 70 V VRRM, 4.0 ns trr, 1.25 V VF @ 150 mA | Larger footprint, higher VF at high current, non-automotive qualified | Use only in cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with BAV99W-7-F and MMBD7000-7-F, the BAW56WQ-7-F uniquely combines AEC-Q101 compliance, 75 V blocking, and 4.0 ns trr in SOT323-making it the sole choice for automotive signal integrity applications requiring both reliability and speed.

FAQ
What is the pin configuration of BAW56WQ-7-F?
The BAW56WQ-7-F uses a standard SOT323 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This common-cathode dual-diode arrangement is confirmed in the device's internal schematic diagram and top-marking layout (KJC YM), and is consistent across Diodes' datasheet Rev. 14–2.
Is BAW56WQ-7-F suitable for 5 V logic-level clamping?
Yes-its 0.855 V forward voltage at 10 mA and 2.0 pF junction capacitance ensure minimal loading and fast response on 5 V GPIO lines. It reliably clamps transients to within 0.7 V above VCC or below GND, meeting IEC 61000-4-2 Level 4 ESD immunity requirements when used with appropriate series impedance.
How does BAW56WQ-7-F differ from the standard BAW56W-7-F?
The BAW56WQ-7-F is the AEC-Q101 qualified, PPAP-capable variant manufactured in IATF 16949 certified facilities, with controlled change management for automotive use. The BAW56W-7-F lacks formal automotive qualification and is intended for commercial-grade applications, though both share identical electrical specs and SOT323 packaging.
Can BAW56WQ-7-F replace a single discrete diode in a design?
No-it is a dual-diode device with shared cathode; replacing a single diode requires verifying whether the circuit uses independent or common-cathode topology. If the original design uses separate cathodes or anodes, direct substitution may cause unintended conduction paths or violate voltage isolation requirements.
