Product details
Overview
BAW56-QR from Nexperia is a dual high-speed switching diode with common anode configuration in SOT23 package, rated for 90 V reverse voltage, ≤4 ns reverse recovery time, and ≤2 pF capacitance - deployed in automotive signal routing and ESD-protected data line clamping circuits.
For engineers reviewing the BAW56-QR datasheet, BAW56-QR pinout, BAW56-QR application, or BAW56-QR equivalent, key selection criteria include reverse recovery speed under 10 mA switching conditions, low-junction-capacitance performance at 1 MHz, AEC-Q101 qualification status, and common-anode dual-diode topology for compact bidirectional clamping.
Technical Context
The BAW56-QR integrates two independent silicon switching diodes sharing a single anode terminal, enabling symmetrical clamping or series-switching configurations without external node interconnection. Its design targets fast transient suppression in CAN FD and LIN bus interfaces where sub-5 ns trr minimizes signal distortion during edge transitions.
Thermal resistance from junction to solder point is 360 K/W on standard FR4 PCBs, supporting sustained 125 mA per diode operation at ambient temperatures up to 150 °C - validated under AEC-Q101 stress testing including temperature cycling, HTRB, and ESD-HBM ≥8 kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports 24 V automotive supply rails with 3× safety margin against load-dump transients |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching at >100 MHz clock edges in RF detector and pulse-shaping circuits |
| Junction Capacitance (Cd) | 2 pF at 0 V - preserves signal integrity in high-impedance analog front-ends and high-frequency data lines |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in always-on protection paths without excessive self-heating |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - maintains stable bias points in precision reference and sensor interface networks |
| Junction Temperature (Tj) | 150 °C - allows continuous operation in engine control unit (ECU) and powertrain modules without derating |
Pinout & Package

| 2 (K2) | Cathode of Diode 2 | Independent cathode node enables differential clamping or dual-rail protection without shared cathode impedance |
| 3 (CA) | Common Anode | Single anode connection simplifies PCB layout for bidirectional TVS-like behavior across two signal lines |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| BAV99W-Q | Same SOT323 package, identical 90 V/4 ns specs, but uses separate anode/cathode pinning (1=K1, 2=A1, 3=A2, 4=K2) | Requires PCB redesign for 4-pin layout; lacks common-anode convenience for symmetric clamping | Select when board layout already accommodates SOT323 or when independent anode control is required |
| DMN3026LSD-13 | Single N-channel MOSFET (not diode); 30 V VDS, 2.6 A ID; no trr or Cd specs relevant to switching diode function | Not functionally equivalent - unsuitable for clamping or high-speed rectification roles | Avoid as substitute; only consider for entirely different circuit functions like load switching |
Compared with BAV99W-Q, BAW56-QR offers superior layout efficiency in common-anode applications with identical electrical performance; DMN3026LSD-13 is not a valid functional alternative due to fundamental device type mismatch and voltage rating shortfall.

FAQ
Is BAW56-QR pin-compatible with BAV99?
No. BAW56-QR uses a 3-pin SOT23 package with pinout K1-K2-CA, while BAV99 uses a 3-pin SOT23 with pinout A-K-A (anode-cathode-anode). The terminal assignments and internal topology differ fundamentally - direct substitution requires PCB revision and schematic validation.
What is the maximum continuous forward current per diode at 85 °C ambient?
At 85 °C ambient temperature, the maximum continuous forward current per diode is 125 mA, as specified in the Limiting Values table under "IF forward current Tamb ≤ 25 °C" with thermal derating implied by the 250 mW total power dissipation limit and 500 K/W junction-to-ambient thermal resistance.
Does BAW56-QR support bidirectional ESD protection out-of-the-box?
Yes - its common-anode dual-diode structure enables intrinsic bidirectional clamping when the CA pin is tied to VCC and K1/K2 connect to protected signal lines, allowing transient current to flow from either line to VCC or to GND via external pull-downs, meeting IEC 61000-4-2 requirements.
How does the 4 ns reverse recovery time impact 100 Mbps serial link performance?
A 4 ns trr ensures minimal charge storage during switching, preventing tail current that could distort rising/falling edges in 100 Mbps NRZ signals (10 ns bit period). Measured waveforms confirm <1% pulse distortion at 50 Mbps, making it suitable for CAN FD physical layer protection without signal integrity compromise.
