Product details
Overview
BAW56S from Nexperia is a dual-common-anode high-speed switching diode array in SOT363-3 (TSSOP6) package, rated for 90 V reverse voltage, ≤4 ns reverse recovery time, and ≤2 pF capacitance per diode, used in high-frequency signal routing and ESD-protected I/O interface circuits.
For engineers reviewing the BAW56S datasheet, BAW56S pinout, BAW56S application, or BAW56S equivalent, this page delivers verified electrical parameters, validated dual-diode topology, thermal resistance (255 K/W), junction temperature limit (150 °C), and real-world switching performance under pulsed IF = 10 mA conditions.
Technical Context
The BAW56S integrates four diodes in a single SOT363-3 package with two independent common-anode pairs: pins 1–2–6 form one pair (K1/K2/A1;A2), and pins 3–4–5 form another (A3;A4/K3/K4). It operates as a bidirectional clamping and fast-switching element in signal path protection.
Its ≤4 ns trr and ≤2 pF Cd enable operation up to ~100 MHz in RF detector, logic-level translation, and high-speed data line steering applications; leakage remains ≤0.5 µA at VR = 80 V and 25 °C, supporting low-power standby integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports rail-to-rail signal clamping in 3.3 V to 24 V digital interfaces without breakdown. |
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in >25 MHz clock distribution and pulse shaping circuits. |
| Diode Capacitance (Cd) | 2 pF - minimizes signal loading on high-impedance nodes such as ADC inputs or RF mixer ports. |
| Forward Voltage (VF) | 855 mV @ 10 mA - ensures low conduction loss in active bias networks and level-shifting paths. |
| Thermal Resistance (Rth(j-sp)) | 255 K/W - defines junction-to-solder-point thermal path for PCB layout thermal relief design. |
| Junction Temperature (Tj) | 150 °C - sets maximum allowable operating temperature for reliability in enclosed industrial enclosures. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 6-pin surface-mount plastic package with 0.65 mm lead pitch and exposed solder pad footprint per Fig. 7 and Fig. 8 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Provides dedicated cathode node for first common-anode diode pair (with Pin 6). |
| 2 | Cathode (Diode 2) | Second cathode in first common-anode pair; enables dual-path clamping from shared anode (Pin 6). |
| 3 | Common Anode (Diodes 3 & 4) | Shared anode terminal for second diode pair; allows independent cathode routing via Pins 4 and 5. |
| 4 | Cathode (Diode 3) | Cathode of second diode pair; used for bidirectional signal limiting on separate I/O lines. |
| 5 | Cathode (Diode 4) | Second cathode tied to Pin 3 anode; supports differential clamping or redundant protection paths. |
| 6 | Common Anode (Diodes 1 & 2) | Shared anode for first diode pair; simplifies PCB routing when both cathodes serve same reference rail. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-anode topology | Enables compact dual-channel clamping with only three external connections per pair (anode + two cathodes). |
| 4 ns reverse recovery time | Reduces switching-induced ringing and cross-talk in multi-GHz data lines and USB 2.0/3.0 signal paths. |
| 2 pF diode capacitance | Maintains signal integrity above 100 MHz by limiting capacitive loading on high-speed traces. |
| 0.5 µA max reverse leakage @ 80 V | Preserves battery life and logic threshold stability in always-on sensor interface and wake-up circuits. |
| 150 °C max junction temperature | Supports operation in sealed industrial controllers and automotive under-hood modules without derating. |
Applications
| USB 2.0 Data Line Protection | LVDS Receiver Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99S | Same SOT363-3 package but single common-cathode dual-diode configuration; trr = 4 ns, Cd = 2 pF, VR = 70 V. | Requires reversed PCB layout for cathode-referenced clamping; lower VR limits use in 24 V industrial buses. | Select when clamping to ground is preferred and 70 V rating suffices; not suitable for anode-referenced rail clamping. |
| MMBD7000 | SOT23-3 package; dual series diodes (not common-anode); trr = 4 ns, Cd = 2 pF, VR = 70 V, higher Rth(j-sp) = 350 K/W. | Requires two separate placements per channel; lacks integrated dual-anode flexibility for compact I/O routing. | Choose for cost-sensitive consumer designs where board space is less constrained and thermal margin is adequate. |
Compared with BAV99S and MMBD7000, the BAW56S uniquely provides two independent common-anode pairs in one footprint-enabling simultaneous clamping of two differential signal pairs to separate supply rails while minimizing trace inductance and layout complexity.

FAQ
What is the maximum continuous forward current per diode in the BAW56S?
The BAW56S supports 250 mA per diode at case temperature (Ts) = 60 °C, with derating above that temperature. At ambient conditions, the practical continuous rating is 100 mA per diode due to thermal coupling in the shared package. This value is defined in Table 5 (Limiting values) and confirmed by the 350 mW total power dissipation limit.
Can the BAW56S be used for bidirectional TVS-like clamping?
No-the BAW56S is a silicon switching diode, not a TVS device. It provides unidirectional clamping (anode-to-cathode conduction) and lacks the avalanche breakdown behavior required for symmetric transient suppression. For bidirectional protection, two BAW56S devices must be used back-to-back or paired with dedicated TVS arrays.
Is the BAW56S qualified for automotive applications?
No-the BAW56S is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 15 and does not list AEC-Q101 qualification. It is intended for industrial, computing, and consumer applications where extended temperature operation (−65 °C to +150 °C) is needed but automotive-grade reliability testing is not required.
How does the dual common-anode structure affect PCB layout?
The dual common-anode structure (Pins 3 and 6) allows two independent clamping paths sharing one anode node each-reducing net count and enabling compact routing. Layout must maintain equal trace length to Pins 1/2 and 4/5 respectively, and avoid thermal vias under Pin 3 or 6 to preserve thermal resistance specification (255 K/W).
