Product details
Overview
BAW56 from Nexperia is a dual high-speed switching diode in SOT23 package with common anode configuration, 90 V reverse voltage rating, ≤4 ns reverse recovery time, ≤2 pF capacitance, and 215 mA continuous forward current per diode-used in compact DC-DC converter snubbers and high-frequency signal routing.
For engineers reviewing the BAW56 datasheet, BAW56 pinout, BAW56 application, or BAW56 equivalent, this page delivers verified electrical specs, validated dual-diode SOT23 terminal mapping, real-world switching use cases, and direct alternatives for fast-switching discrete selection in space-constrained designs.
Technical Context
The BAW56 integrates two independent silicon switching diodes sharing a common anode (Pin 3), enabling compact dual-path clamping or steering without external interconnects. Its ≤4 ns trr and ≤2 pF Cd support operation up to 100 MHz in RF detector and pulse shaping circuits.
Thermal resistance of 500 K/W (junction-to-ambient, free air) and 360 K/W (junction-to-solder point) confirms suitability for low-power SMT layouts on FR4 PCBs with standard copper thickness and tin plating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports input rail clamping in 24 V and 48 V industrial power supplies |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching at ≥100 MHz in RF envelope detectors |
| Diode Capacitance (Cd) | ≤2 pF at 0 V - minimizes signal loading in high-Z analog switch nodes |
| Forward Current (IF) | 215 mA per diode - sufficient for logic-level signal steering in microcontroller I/O protection |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in low-duty-cycle pulse applications |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance bias networks |
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, designed for reflow soldering on standard FR4 PCBs with single-sided copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode, Diode 1) | Output node for first diode path; connects to load or signal line requiring unidirectional conduction |
| 2 | K2 (Cathode, Diode 2) | Independent output node for second diode path; enables dual-rail clamping or polarity-select routing |
| 3 | CA (Common Anode) | Shared input node; ties both diodes to same supply or reference, simplifying layout in dual-cathode configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual diode with common anode | Reduces board area by 40% vs. two discrete SOT23 diodes; eliminates trace routing between anodes |
| ≤4 ns reverse recovery time | Enables reliable operation in 50–100 MHz clock distribution and RF sampling circuits |
| ≤2 pF junction capacitance | Preserves rise/fall times in <1 ns digital edge routing and high-frequency detector inputs |
| 90 V peak reverse voltage | Supports transient suppression in 24 V/48 V bus interfaces without derating |
Applications
| DC-DC Converter Snubber | RF Signal Detector |
|---|---|
Use Scenario: Suppresses voltage spikes across MOSFET drains in 500 kHz buck converters using ceramic output capacitors. IC Role / Device Role / Timing Role: Dual-cathode clamping diode absorbing inductive kickback during switch-off transitions. Use Value: 4 ns trr prevents snap-off oscillation; common anode simplifies connection to ground-referenced snubber RC network. |
Use Scenario: Demodulates AM signals in 868 MHz ISM-band receiver front-ends with minimal distortion. IC Role / Device Role / Timing Role: High-speed envelope detector diode operating in small-signal square-law region. Use Value: 2 pF Cd avoids detuning matching networks; low leakage preserves DC offset accuracy at µV-level inputs. |
| Microcontroller I/O Protection | Digital Logic-Level Steering |
Use Scenario: Clamps ESD transients on 3.3 V GPIO lines connected to external sensors in industrial PLC modules. IC Role / Device Role / Timing Role: Bidirectional transient suppressor using two cathodes tied to I/O pins and common anode to VCC. Use Value: 0.5 µA IR at 80 V prevents false triggering; SOT23 footprint fits tight 0.5 mm pitch routing. |
Use Scenario: Routes active-low reset signals from multiple sources to a single MCU reset input with isolation. IC Role / Device Role / Timing Role: OR-gate implementation via common-anode diode logic with pull-up resistor. Use Value: 855 mV VF at 10 mA ensures valid logic-low threshold under 10 kΩ pull-up; dual structure halves component count. |
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 |
|---|---|---|---|
| BAV99,215 | Same SOT23 package, but common cathode (not common anode); trr = 4 ns, VR = 70 V | Requires inverted PCB layout (anodes routed separately); lower VR limits use in 48 V systems | Select when existing design uses cathode-common topology or requires tighter VF spread (typ. 715 mV at 1 mA) |
| MMBD7000LT1G | Common anode, SOT23, VR = 70 V, trr = 6 ns, Cd = 2.5 pF | Higher capacitance and slower recovery reduce RF bandwidth margin; rated only to 70 V | Choose if cost sensitivity outweighs 20 V VR and 2 ns trr penalties in non-critical 24 V applications |
Compared with BAV99,215 and MMBD7000LT1G, the BAW56 uniquely combines 90 V VR, ≤4 ns trr, and common-anode SOT23 in one device-making it optimal for 48 V snubbers and dual-rail RF detectors where voltage headroom and timing precision are critical.

FAQ
Is the BAW56 suitable for automotive applications?
No. The BAW56 is explicitly marked as non-automotive qualified in its revision history and legal disclaimers. It lacks AEC-Q101 qualification, automotive-grade temperature cycling validation, and extended reliability testing. For automotive use, Nexperia offers the BAW56-Q series, which undergoes full AEC-Q101 stress testing and includes enhanced process controls.
What is the maximum pulsed forward current the BAW56 can handle?
The BAW56 supports 4 A non-repetitive peak forward current (IFSM) for 1 µs square-wave pulses at Tj(init) = 25 °C. This rating assumes proper thermal management on FR4 PCBs with standard copper; exceeding 1 µs pulse width reduces allowable current due to junction heating-e.g., 1 A at 1 ms.
How does the common-anode configuration affect PCB layout compared to common-cathode diodes?
The common-anode (Pin 3) forces both diode anodes to share one net-ideal for clamping to a positive rail or pull-up node. Unlike common-cathode parts (e.g., BAV99), no separate anode traces are needed, reducing layer count and parasitic inductance. Layout must route K1 and K2 (Pins 1 and 2) independently to their respective loads or signal paths.
Can the BAW56 replace a single discrete diode in a circuit?
Yes-but only if the circuit uses only one of the two diodes and leaves the other cathode unconnected. Pin 1 (K1) and Pin 2 (K2) operate independently; unused cathode must be left floating or tied to a benign potential (e.g., ground via high-value resistor). Do not short either cathode to CA, as that creates a shorted diode path.
