Product details
Overview
BAW56S-QF from Nexperia is a dual-common-anode high-speed switching diode array in SOT363-3 (TSSOP6) package, comprising four diodes configured as two independent common-anode pairs (A1/A2–K1/K2 and A3/A4–K3/K4), with trr ≤ 4 ns, Cd ≤ 2 pF, VR = 90 V, and qualified to AEC-Q101 for automotive signal routing and ESD protection in CAN/LIN bus interfaces.
For engineers reviewing the BAW56S-QF datasheet, BAW56S-QF pinout, BAW56S-QF application, or BAW56S-QF equivalent, this device supports high-frequency signal steering, low-capacitance transient suppression, and space-constrained dual-channel switching where fast recovery and automotive-grade reliability are required.
Technical Context
The BAW56S-QF integrates four discrete high-speed diodes in a single 6-pin TSSOP package, arranged as two electrically isolated common-anode dual-diode structures - enabling bidirectional clamping or dual-path signal conditioning without cross-talk. Its 4 ns reverse recovery time and 2 pF junction capacitance support operation up to ~100 MHz in digital signal paths.
Designed for automotive environments, it meets AEC-Q101 stress test requirements including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV), with guaranteed operation from −65 °C to +150 °C junction temperature and 90 V repetitive peak reverse voltage per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports 24 V automotive supply rail transients and ISO 7637-2 pulse 1/2a suppression. |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables clean switching in >50 MHz clock distribution and data line steering. |
| Junction Capacitance (Cd) | ≤ 2 pF at 0 V - minimizes signal loading on high-speed digital lines (e.g., LIN, CAN FD stubs). |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in active clamping and level-shifting circuits. |
| Reverse Leakage (IR) | ≤ 0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance sensor interface nodes. |
| Thermal Resistance (Rth(j-sp)) | 255 K/W - enables 350 mW total power dissipation on standard FR4 PCB with single-sided copper. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm body, 0.65 mm lead pitch, gull-wing leads, JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Output node for first common-anode pair; connects to signal path requiring clamping or rectification. |
| 2 | Cathode (Diode 2) | Independent cathode for Diode 1's counterpart; enables dual-signal routing from shared anode (Pin 6). |
| 3 | Common Anode (Diodes 3 & 4) | Shared anode terminal for second dual-diode section; used for bidirectional transient absorption or dual-rail referencing. |
| 4 | Cathode (Diode 3) | Cathode of second diode pair; routed to secondary signal line (e.g., backup CAN_H or LIN bus). |
| 5 | Cathode (Diode 4) | Complementary cathode to Pin 4; allows independent control or monitoring of second channel. |
| 6 | Common Anode (Diodes 1 & 2) | Primary shared anode node; ties to VCC or reference rail for active clamping or level translation. |
Key Features
| Feature | Design Value |
|---|---|

| Dual common-anode topology | Two independent 2-diode sections reduce board area by 40% vs. discrete SOD-323 solutions in dual-bus protection. |
| 4 ns trr with low Qrr | Minimizes switching loss and ringing in 10–100 MHz signal paths, critical for CAN FD and Ethernet PHY front-end protection. |
| 2 pF capacitance at 0 V | Preserves signal edge rate (tr < 1 ns degradation) on 50 Ω transmission lines up to 200 Mbps. |
| −65 °C to +150 °C operation | Supports extended-temperature deployment in engine control units (ECUs) and ADAS domain controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAW56,115 (Nexperia) | Same die, but in SOT363 (non–SOT363-3) package; no AEC-Q101 qualification; trr = 4 ns, Cd = 2 pF. | Not approved for automotive use; suitable only for industrial or consumer-grade designs with relaxed qualification needs. | Select when AEC-Q101 is unnecessary and cost sensitivity outweighs automotive compliance requirements. |
| DMN2016LFG-7 (Diodes Inc.) | Single dual-diode in SOT-363; trr = 3.5 ns, Cd = 1.8 pF, VR = 80 V, AEC-Q101 qualified, but lacks dual-common-anode pinout. | Requires external anode tie for dual-cathode operation; less flexible for independent dual-channel clamping. | Choose when lower trr/Cd is prioritized over pinout flexibility and 90 V VR margin is not required. |
Compared with BAW56,115, the BAW56S-QF adds automotive qualification and tighter package dimensional control; versus DMN2016LFG-7, it provides native dual-common-anode routing for simplified PCB layout in multi-rail protection schemes.

FAQ
What is the maximum junction temperature and thermal resistance of the BAW56S-QF?
The BAW56S-QF has a maximum junction temperature (Tj) of 150 °C and a thermal resistance from junction to solder point (Rth(j-sp)) of 255 K/W when mounted on a standard FR4 PCB with single-sided copper and tin-plated finish. This allows continuous operation at 350 mW total power dissipation under defined board conditions.
How does the dual-common-anode configuration benefit circuit design?
The dual-common-anode structure (Pins 6 and 3) enables two independent, isolated dual-diode sections - allowing simultaneous clamping of two signal lines to separate reference rails without internal coupling. This simplifies layout for differential bus protection (e.g., CAN_H/CAN_L) and eliminates need for external anode traces or discrete components.
Is the BAW56S-QF suitable for 5 V or 3.3 V logic-level ESD protection?
Yes - its 2 pF capacitance at 0 V and ≤ 0.5 µA leakage at 80 V ensure minimal signal distortion on 5 V and 3.3 V digital lines. It is widely deployed in USB 2.0, LIN, and SPI interfaces where IEC 61000-4-2 Level 4 ESD immunity and sub-1 ns edge preservation are required.
Does the BAW56S-QF require external biasing or drive circuitry?
No - the BAW56S-QF is a passive high-speed switching diode array with no control inputs or bias requirements. It operates solely based on applied voltage polarity and magnitude relative to its anode/cathode terminals, making it compatible with all standard clamping, steering, and level-shifting topologies without additional drivers or power rails.
