Product details
Overview
BAW56DW-7 from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, featuring two independent BAW56 diodes with 75 V peak reverse voltage, 300 mA forward current rating, and 4.0 ns reverse recovery time. It serves as a compact signal routing or polarity protection element in low-voltage digital interface and RF front-end circuits.
For engineers reviewing the BAW56DW-7 datasheet, BAW56DW-7 pinout, BAW56DW-7 application, or BAW56DW-7 equivalent, key selection criteria include fast switching performance (trr ≤ 4.0 ns), dual-diode integration in ultra-small SOT363, low forward voltage (VF ≤ 0.855 V @ 10 mA), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual diode array integrates two independent, matched BAW56 switching diodes in a single 6-pin SOT363 package. Each diode exhibits low capacitance (CT = 2.0 pF @ 0 V), fast recovery (trr = 4.0 ns), and stable reverse leakage (IR ≤ 2.5 µA @ 75 V, 25°C).
The device operates across -65°C to +150°C, supports 200 mW total package power dissipation, and maintains specified electrical behavior under pulsed forward/reverse conditions per JEDEC standards, making it suitable for high-frequency signal clamping and logic-level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 75 V - Supports DC blocking and transient suppression up to 75 V in signal path applications |
| Reverse Recovery Time | 4.0 ns - Enables reliable operation in >100 MHz digital switching and RF detector circuits |
| Forward Voltage | 0.855 V @ 10 mA - Minimizes voltage drop and power loss in low-voltage logic interface paths |
| Total Capacitance | 2.0 pF @ 0 V - Preserves signal integrity in high-frequency routing without excessive loading |
| Thermal Resistance | 625 °C/W - Requires careful PCB layout (FR-4 pad design per AP02001) for thermal management at full load |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics use including infotainment and body control modules |
Pinout & Package
SOT363 is a 6-pin, ultra-small surface-mount plastic package (2.10 × 1.30 × 0.95 mm) with gull-wing leads, rated UL 94V-0, moisture sensitivity level 1, and matte tin-plated Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode's forward conduction path; connects to signal source or logic line |
| 2 | Cathode of Diode 1 | Output/return node for Diode 1; ties to reference rail or downstream circuit |
| 3 | Common Cathode | Shared cathode connection for both diodes; enables OR-ing or dual-anode configurations |
| 4 | Anode of Diode 2 | Independent input node for second diode; supports separate signal routing or redundancy |
| 5 | Cathode of Diode 2 | Output node for Diode 2; electrically isolated from Diode 1 except via shared cathode (Pin 3) |
| 6 | NC / Not Internally Connected | No internal bond; left unconnected per datasheet - must be floated or tied to ground only if required by layout EMI mitigation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent diodes in one package | Reduces board space by ~40% vs. two discrete SOT23 diodes; simplifies layout for dual-path protection |
| Ultra-fast reverse recovery | 4.0 ns trr ensures minimal switching distortion in 50–200 MHz clock/data lines and RF envelope detection |
| Low junction capacitance | 2.0 pF per diode minimizes signal attenuation and phase shift in high-speed analog and digital interfaces |

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 | Same SOT363 package; slightly higher VF (0.875 V @ 10 mA); identical trr (4.0 ns) and VRWM (75 V) | Identical functional role; marginally higher forward drop may affect low-voltage logic translation accuracy | Select when BAW56DW-7 is unavailable and VF tolerance allows ≤0.02 V increase |
| MMBD7000DW-7-F | Higher VRWM (100 V); lower CT (1.5 pF); same trr (4.0 ns); RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification; better suited for industrial/commercial RF where 100 V blocking is needed | Choose for non-automotive designs requiring enhanced reverse voltage margin and lower capacitance |
Compared with BAV99DW-7-F and MMBD7000DW-7-F, the BAW56DW-7 offers optimal balance of automotive qualification, low VF, and proven dual-diode matching - critical for safety-critical CAN and USB protection where consistency and reliability are prioritized over marginal parameter shifts.

FAQ
What is the maximum operating temperature for BAW56DW-7?
The BAW56DW-7 is rated for continuous operation from -65°C to +150°C junction temperature. Its thermal resistance (RθJA = 625°C/W) requires adherence to the recommended FR-4 pad layout (AP02001) to sustain 200 mW power dissipation at ambient temperatures up to +85°C without exceeding TJ(max).
Is Pin 6 internally connected?
No, Pin 6 is not internally connected per the official Diodes Incorporated datasheet DS30146 Rev. 11-2. It must remain unconnected unless used for mechanical anchoring or EMI shielding - in which case grounding is permissible but does not affect electrical function.
How does the shared cathode (Pin 3) affect circuit design?
Pin 3 serves as the common cathode for both diodes, enabling configurations like dual-anode clamping or OR-ing logic. This architecture reduces external component count but requires that both diodes share the same cathode reference - limiting independent biasing of the two elements.
Can BAW56DW-7 replace single-diode SOT23 packages in existing designs?
Yes, with layout adaptation: the SOT363 footprint differs from SOT23, requiring PCB redesign. Electrically, each diode matches BAW56 specifications, so functionality is preserved. However, the shared cathode (Pin 3) and NC Pin 6 demand schematic review to avoid unintended shorts or open nodes.
