Product details
Overview
BAW56W from Nexperia is a dual high-speed switching diode in common-anode configuration, designed for fast signal routing and clamping in compact digital and RF interfaces. It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 2 pF junction capacitance, and VR = 90 V peak reverse voltage, enabling reliable operation in 5 V–24 V logic-level switching circuits such as USB data line protection and Ethernet PHY bias networks.
For engineers reviewing the BAW56W datasheet, BAW56W pinout, BAW56W application, or BAW56W equivalent, key selection criteria include verified dual-diode timing symmetry, SOT323 thermal resistance (Rth(j-a) = 625 K/W), low-leakage performance at 80 V bias (IR ≤ 0.5 µA), and compatibility with reflow-soldered high-density PCB layouts.
Technical Context
The BAW56W integrates two independent silicon switching diodes sharing a single anode terminal, forming a compact dual-cathode topology optimized for bidirectional transient suppression and level translation. Its epitaxial planar structure ensures consistent trr ≤ 4 ns under IF = 10 mA / IR = 10 mA test conditions and maintains Cd ≤ 2 pF at 0 V reverse bias and 1 MHz.
Thermal design relies on FR4 PCB mounting with single-sided copper, where Rth(j-sp) = 300 K/W enables stable operation up to Tj = 150 °C. The device operates within Tamb = −65 °C to +150 °C and supports pulsed forward currents up to 4 A (tp = 1 µs) without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Dual high-speed switching diode, common-anode configuration |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables >100 MHz signal switching without tail current distortion |
| Junction Capacitance (Cd) | ≤ 2 pF at VR = 0 V, f = 1 MHz - minimizes signal loading in RF and high-speed digital paths |
| Peak Reverse Voltage (VRRM) | 90 V - supports industrial I/O protection up to 24 V systems with safety margin |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in logic-level clamp applications |
| Reverse Leakage (IR) | ≤ 0.5 µA at VR = 80 V, Tamb = 25 °C - preserves signal integrity in high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 200 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 layout |
Pinout & Package
Encapsulated in SC-70 (SOT323) package: 3-terminal surface-mount plastic case measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and standardized reflow footprint per Figure 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Provides dedicated cathode connection for first diode; routed independently for asymmetric clamping |
| 2 | K2 (Cathode of Diode 2) | Enables dual-path signal conditioning - e.g., separate data line protection on D+ and D− |
| 3 | CA (Common Anode) | Shared anode node simplifies biasing in rail-to-rail clamp configurations and reduces trace count |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal propagation delay skew between dual channels in differential signal paths |
| Low-junction capacitance | Cd ≤ 2 pF prevents high-frequency attenuation in USB 2.0 and CAN FD signal lines |
| Low leakage current | IR ≤ 0.5 µA at 80 V supports accurate voltage threshold detection in battery-monitoring circuits |
| Thermally robust SOT323 | Rth(j-a) = 625 K/W allows sustained 130 mA DC operation on standard PCB without heatsinking |
Applications
| USB 2.0 Data Line Protection | Ethernet PHY Bias Clamping |
|---|---|
Use Scenario: Protecting D+ and D− lines from ESD transients and overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Dual-cathode clamping diode providing symmetric low-capacitance path to VBUS and GND rails. Use Value: 2 pF capacitance avoids signal integrity degradation at 480 Mbps; 4 ns trr prevents data eye closure. |

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,115 | Higher trr (≤ 6 ns), identical SOT323 package and CA/K1/K2 pinout | Slightly reduced timing margin in >100 MHz clock distribution networks | Select when cost sensitivity outweighs sub-nanosecond recovery needs |
| MMBD7000LT1G | Lower VRRM (100 V), higher Cd (4 pF), same dual-common-anode topology | Increased capacitive loading limits use in >50 MHz signal paths | Prefer for higher-voltage industrial I/O where speed is secondary to breakdown margin |
Compared with BAV99W and MMBD7000LT1G, the BAW56W offers the lowest trr (4 ns) and Cd (2 pF) among SOT323 dual diodes, making it optimal for high-frequency signal integrity–critical roles like USB 2.0 and Ethernet PHY interface protection.

FAQ
Is the BAW56W suitable for automotive applications?
No. The BAW56W is explicitly marked as non-automotive qualified in its revision history (v.7, July 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and temperature cycling validation required for vehicle environments. For automotive alternatives, consult Nexperia's -Q qualified BAW56W-Q series or BAV99W-Q variants.
What is the maximum continuous forward current rating for the BAW56W?
The absolute maximum continuous forward current per diode is 130 mA at Tamb ≤ 25 °C on a standard FR4 PCB with single-sided copper. This rating assumes no derating and drops linearly above 25 °C ambient, reaching zero at Tamb = 150 °C per the thermal resistance curve (Rth(j-a) = 625 K/W).
Can the BAW56W be used in place of a single-diode package like the BAV99?
Yes, but only if the circuit requires dual-diode functionality with shared anode. The BAW56W is not a drop-in replacement for single-diode packages due to its 3-pin common-anode topology. Using it as a single diode wastes one cathode terminal and may introduce unintended coupling; verify layout isolation and thermal impact before substitution.
Does the BAW56W support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint dimensions (Figure 9) for the SOT323 package, specifying 3.65 mm × 2.1 mm board area with 1.425 mm × 0.9 mm solder lands. Recommended transport direction aligns with pin 1–3 axis to ensure uniform wetting and avoid shadowing of pin 2 during conveyor passage.
