Product details
Overview
BAW56W/DG/B3X from Nexperia is a dual high-speed switching diode in SOT23 package with common anode configuration, rated for 90 V reverse voltage, ≤4 ns reverse recovery time, and ≤2 pF capacitance. It enables fast signal routing and clamping in compact DC-DC converter feedback paths and RF detector circuits.
For engineers reviewing the BAW56W/DG/B3X datasheet, BAW56W/DG/B3X pinout, BAW56W/DG/B3X application, or BAW56W/DG/B3X equivalent, key selection criteria include trr ≤4 ns at IF=10 mA, VR=90 V, Cd≤2 pF at 1 MHz, and thermal resistance Rth(j-a)=500 K/W on FR4 PCB.
Technical Context
The BAW56W/DG/B3X integrates two independent silicon switching diodes sharing a common anode terminal, forming a dual-diode structure optimized for high-frequency signal steering and transient suppression. Its low-junction-capacitance (2 pF) and ultrafast recovery (4 ns) support operation up to ~100 MHz in small-signal switching roles.
It operates within -65 °C to 150 °C ambient range, with forward current limited to 125 mA per diode at 25 °C ambient and 215 mA peak under derated conditions. Thermal resistance from junction to solder point is 360 K/W, enabling reliable performance in thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports input rail clamping in 48 V industrial power supplies without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >25 MHz clock distribution and pulse shaping circuits |
| Diode Capacitance (Cd) | 2 pF at 0 V, 1 MHz - minimizes signal loading in RF detector and mixer bias networks |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in precision analog switch and level-shift applications |
| Reverse Current (IR) | 0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance sample-and-hold and sensor interface nodes |
| Junction Temperature (Tj) | 150 °C - allows sustained operation in sealed enclosures with limited airflow |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, standard footprint for reflow and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Provides dedicated cathode path for first diode; used in dual-path clamping or OR-ing configurations |
| 2 (K2) | Cathode of Diode 2 | Independent cathode node enabling separate signal routing or differential detection |
| 3 (CA) | Common Anode | Shared anode connection simplifies bias network design and reduces PCB trace count in dual-diode topologies |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal tail current during turn-off, critical for reducing cross-conduction in synchronous rectifier drivers |
| Low junction capacitance | Cd ≤ 2 pF limits capacitive feedthrough in RF envelope detectors and high-frequency logic-level translators |
| Low leakage current | IR ≤ 0.5 µA at 80 V preserves accuracy in high-impedance voltage divider and reference buffer circuits |
| Thermal robustness | Rth(j-sp) = 360 K/W enables stable operation at 125 mA continuous current on standard FR4 with tin-plated copper |
Applications
| DC-DC Converter Feedback Path | RF Signal Detector |
|---|---|
Use Scenario: Clamping and steering feedback signals in isolated flyback and forward converters operating at 100–500 kHz.

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/DG/B3X | trr = 4 ns (same), but VF = 1.25 V at 150 mA vs. BAW56W's 855 mV at 10 mA; higher IF rating (200 mA) | Better suited for higher-current switching; less optimal for low-VF precision analog paths | Select when forward current exceeds 100 mA or when higher surge tolerance is required |
| MMBD7000LT1G | trr = 4 ns (same), Cd = 2.5 pF (slightly higher), VR = 70 V (lower than 90 V) | Limited to ≤70 V systems; marginally higher capacitance affects RF bandwidth above 500 MHz | Choose only if 70 V VR suffices and cost sensitivity outweighs 20 V VR margin |
Compared with BAV99W/DG/B3X and MMBD7000LT1G, the BAW56W/DG/B3X delivers superior low-current forward voltage (855 mV @ 10 mA) and highest VR rating (90 V), making it optimal for precision feedback clamping and industrial 48 V system protection where leakage and voltage margin are critical.

FAQ
What is the maximum continuous forward current per diode at 25 °C ambient?
The BAW56W/DG/B3X supports 125 mA continuous forward current per diode at Tamb ≤ 25 °C when mounted on standard FR4 PCB with single-sided copper. This rating drops to 215 mA only under pulsed conditions (tp = 1 µs, δ ≤ 0.02) and requires strict thermal derating above 25 °C ambient.
Is the BAW56W/DG/B3X automotive qualified?
No. The BAW56W/DG/B3X is explicitly marked as non-automotive qualified in its revision history. Nexperia offers automotive alternatives such as the BAW56-Q series, which undergo AEC-Q101 qualification and include extended temperature testing, failure rate analysis, and PPAP documentation.
How does the common-anode configuration affect circuit layout?
The CA (Pin 3) serves as the shared anode node for both diodes, allowing simplified biasing with a single pull-up resistor or voltage source. This reduces component count and PCB area versus discrete diodes, but requires careful grounding of K1/K2 to avoid unintended conduction paths in bidirectional signal routing.
Can BAW56W/DG/B3X replace BAV99 in existing designs?
Yes, in most cases - both share identical SOT23 pinout (K1-K2-CA), 90 V VR, and 4 ns trr. However, BAW56W has lower VF (855 mV vs. 1.25 V at 150 mA) and tighter IR spec (0.5 µA vs. 2.5 µA), making it preferable for low-power analog signal paths where conduction loss and leakage matter.
