Product details
Overview
BAW56W/DG/B2F from Nexperia is a dual high-speed switching diode in SOT23 package, configured as a common-anode pair for fast signal routing and polarity selection in digital logic interfaces. It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 2 pF junction capacitance, and VR = 90 V peak reverse voltage, enabling use in 50 MHz+ clock line steering and ESD-protected data bus clamping circuits.
For engineers reviewing the BAW56W/DG/B2F datasheet, BAW56W/DG/B2F pinout, BAW56W/DG/B2F application, or BAW56W/DG/B2F equivalent, key selection criteria include verified dual-diode common-anode topology, sub-4 ns trr under IF = 10 mA/IR = 10 mA test conditions, thermal resistance Rth(j-a) = 500 K/W on FR4 PCB, and compatibility with reflow soldering per IPC-J-STD-020.
Technical Context
The BAW56W/DG/B2F integrates two independent silicon switching diodes sharing a single anode terminal, forming a compact dual-diode configuration optimized for bidirectional transient suppression and high-frequency signal path control. Its epitaxial planar structure ensures consistent trr ≤ 4 ns and low forward voltage VF = 855 mV at IF = 10 mA.
This device operates within a junction temperature range of −65 °C to 150 °C and supports repetitive peak forward current IFRM = 500 mA per diode. Thermal performance is characterized by Rth(j-sp) = 360 K/W to solder point on standard FR4 PCB, enabling stable operation in space-constrained industrial control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports rail-to-rail signal clamping in 24 V industrial I/O circuits without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation up to 50 MHz digital switching without tail current distortion |
| Junction Capacitance (Cd) | 2 pF at 0 V - minimizes signal loading on high-impedance RF detector or clock distribution nodes |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low power loss in active-low enable paths and logic-level translation |
| Reverse Leakage (IR) | 0.5 µA at VR = 80 V - maintains signal integrity in battery-backed real-time clock backup circuits |
| Total Power Dissipation (Ptot) | 250 mW - allows continuous dual-diode operation at ambient temperatures up to +85 °C on standard PCB |
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, FR4-compatible footprint per Fig. 8 and Fig. 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Provides dedicated cathode connection for first diode in common-anode pair; routed to signal input or clamp node |
| 2 (K2) | Cathode of Diode 2 | Independent cathode for second diode; enables dual-path clamping or polarity-selective signal routing |
| 3 (CA) | Common Anode | Shared anode terminal tied to reference rail (e.g., VCC or bias voltage); defines dual-diode orientation |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns measured under IF = 10 mA / IR = 10 mA / RL = 100 Ω - eliminates timing skew in synchronous data lines |
| Low junction capacitance | Cd ≤ 2 pF at VR = 0 V / f = 1 MHz - preserves rise/fall times in >100 Mbps LVDS or USB 2.0 stubs |
| Thermal robustness | Rth(j-a) = 500 K/W on single-sided FR4 - sustains 125 mA continuous forward current at Tamb = 70 °C |
| Low leakage performance | IR ≤ 0.5 µA at VR = 80 V and 25 °C - prevents false triggering in high-impedance sensor interface inputs |
| Standardized SMT footprint | SOT23 outline per JEDEC TO-236AB - ensures drop-in replacement and compatibility with automated placement equipment |
Applications
| USB 2.0 Data Line Protection | Industrial Digital Input Conditioning |
|---|---|

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/B2F | trr = 4 ns (same), but VF = 1.25 V at IF = 150 mA - higher forward drop increases conduction loss | Higher Ptot = 300 mW supports heavier drive loads but less suitable for low-power sensor interfaces | Select when higher surge current handling (IFSM = 4 A) is required over ultra-low VF at light loads |
| MMBD7000LT1G | trr = 4 ns (same), Cd = 2.5 pF - 0.5 pF higher capacitance degrades >100 MHz signal fidelity | VR = 70 V - insufficient for 24 V industrial I/O with safety margin; not rated for 90 V systems | Prefer only in cost-sensitive consumer designs where 70 V VR and 2.5 pF Cd meet system margins |
Compared with BAV99W/DG/B2F and MMBD7000LT1G, the BAW56W/DG/B2F uniquely balances 90 V VR, 4 ns trr, and 2 pF Cd in a standardized SOT23 footprint-making it optimal for high-reliability industrial signal routing where voltage margin and bandwidth coexist.

FAQ
What is the maximum junction temperature for continuous operation of BAW56W/DG/B2F?
The BAW56W/DG/B2F has a maximum junction temperature (Tj) rating of 150 °C, validated per IEC 60134 Absolute Maximum Ratings. Continuous operation at this limit requires thermal design ensuring Rth(j-a) ≤ 500 K/W on FR4 PCB with single-sided copper, as specified in Table 6 of the official datasheet.
Does BAW56W/DG/B2F support wave soldering?
Yes, BAW56W/DG/B2F is qualified for wave soldering using the footprint defined in Figure 9 of the datasheet: 2.8 mm × 4.5 mm pad layout with 1.4 mm × 1.2 mm solder resist openings. Peak temperature must not exceed 260 °C for ≤ 10 seconds, consistent with IPC-J-STD-020 requirements for SOT23 packages.
Is BAW56W/DG/B2F automotive-qualified?
No, BAW56W/DG/B2F is explicitly designated as non-automotive qualified per Revision History section 14 of the datasheet. For automotive applications, Nexperia recommends the BAW56-Q series, which undergoes AEC-Q101 qualification and includes enhanced reliability testing for under-hood environments.
How is the common-anode configuration used in practical circuit design?
The CA (Pin 3) terminal connects to a fixed reference voltage (e.g., VCC or bias rail), while K1 and K2 independently route signals to ground or clamping nodes. This enables dual-path functions such as bidirectional ESD protection, OR-ing logic inputs, or polarity-selective signal steering without external bias components.
