Product details
Overview
BAW56S-Q 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 per AEC-Q101 for automotive signal routing and clamping.
For engineers reviewing the BAW56S-Q datasheet, BAW56S-Q pinout, BAW56S-Q application, or BAW56S-Q equivalent, this device supports high-frequency digital signal steering, ESD-protected I/O buffering, and low-capacitance voltage clamping in space-constrained automotive ECUs and ADAS sensor interfaces.
Technical Context
The BAW56S-Q integrates four discrete high-speed diodes in a single 6-pin TSSOP package, arranged as two electrically isolated dual-diode structures sharing common anodes-enabling bidirectional clamping or dual-channel level translation without cross-talk. Its trr ≤ 4 ns and Cd ≤ 2 pF at 1 MHz support operation up to ~100 MHz in fast-switching logic interfaces.
Designed for automotive-grade reliability, it sustains IF = 250 mA per diode at Ts = 60 °C, operates across –65 °C to +150 °C ambient, and meets AEC-Q101 stress test requirements including HTGB, HTRB, and temperature cycling-ensuring robustness in engine control and infotainment power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports 24 V automotive supply rail transient suppression with 2× safety margin. |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables clean switching in >100 MHz digital signal paths without tail current distortion. |
| Diode Capacitance (Cd) | ≤ 2 pF at 0 V, 1 MHz - minimizes signal loading on high-speed data lines (e.g., CAN FD, LIN, SPI). |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in active clamping and logic-level shifting circuits. |
| Reverse Current (IR) | ≤ 0.5 µA at VR = 80 V, 25 °C - maintains high impedance isolation in standby and sleep-mode signal paths. |
| Junction Temperature (Tj) | 150 °C max - allows continuous operation in under-hood environments without derating at full current. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm body, 0.65 mm lead pitch, surface-mount plastic package with exposed thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode of Diode 1 - connects to signal line requiring clamping toward common anode A1/A2. |
| 2 | K2 | Cathode of Diode 2 - forms second leg of first common-anode pair (A1/A2–K1/K2) for differential or redundant clamping. |
| 3 | A3/A4 | Common anode of Diodes 3 and 4 - provides shared positive reference for second independent dual-diode channel. |
| 4 | K3 | Cathode of Diode 3 - routes to secondary signal path (e.g., backup sensor input or alternate bus line). |
| 5 | K4 | Cathode of Diode 4 - completes second dual-diode structure, enabling independent bidirectional protection per channel. |
| 6 | A1/A2 | Common anode of Diodes 1 and 2 - ties to local VCC or bias rail for active clamping or level-shifting function. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in 100+ MHz clock distribution and high-data-rate serial interface protection. |

| AEC-Q101 qualification | Validated for automotive under-hood applications including engine management and ADAS camera modules. |
| Dual common-anode topology | Two independent 2-diode groups allow separate clamping of two signal pairs using one footprint. |

Applications
| Automotive CAN FD Transceiver Protection | High-Speed Digital I/O Clamping |
|---|---|
|
Use Scenario: Protecting CAN FD transceiver pins against ESD and load-dump transients in vehicle networking modules. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between TX/RX lines and VCC/GND rails to limit excursion beyond safe logic thresholds. Use Value: 4 ns trr prevents latch-up during fast edge transitions; 2 pF capacitance avoids signal rise-time degradation on 5 Mbit/s CAN FD buses. |
Use Scenario: Shielding FPGA or MCU GPIOs from overvoltage events in industrial HMI panels and sensor hubs. IC Role / Device Role / Timing Role: Dual-channel rail-to-rail clamping diode array providing simultaneous protection for complementary signal pairs. Use Value: Independent A1/A2 and A3/A4 anodes allow separate biasing for pull-up and pull-down domains without interference. |
| ADAS Camera Interface Level Shifting | Automotive LIN Bus Signal Conditioning |
|
Use Scenario: Translating 1.8 V MIPI CSI-2 signals from image sensors to 3.3 V processor inputs in surround-view systems. IC Role / Device Role / Timing Role: Active clamping diode used in series with resistive divider to enforce precise voltage thresholds at receiver inputs. Use Value: Low VF (855 mV @ 10 mA) ensures minimal offset error; 90 V VR rating accommodates worst-case surge coupling. |
Use Scenario: Improving noise immunity on LIN bus master/slave nodes in body control modules and door modules. IC Role / Device Role / Timing Role: Common-anode dual-diode configuration used for bus-line pull-up stabilization and transient suppression. Use Value: 0.5 µA IR at 80 V ensures negligible leakage current in always-on LIN standby mode, preserving battery life. |
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 |
|---|---|---|---|
| BAV99W-Q | Single common-cathode dual-diode (SOT323), trr = 4 ns, Cd = 2 pF, VR = 70 V, no AEC-Q101 qualification. | Limited to non-automotive consumer or industrial applications due to lower VR and lack of automotive qualification. | Select when cost sensitivity outweighs automotive compliance and 90 V VR headroom is unnecessary. |
| NSR0230P2T5G | Single Schottky diode (SOD-523), VF = 370 mV @ 200 mA, trr not specified (Schottky), VR = 30 V, AEC-Q101 qualified. | Not pin-compatible; lacks dual-diode topology and common-anode architecture required for paired signal protection. | Choose only for ultra-low VF requirements in low-voltage (<3.3 V) clamping where reverse recovery is irrelevant. |
Compared with BAV99W-Q and NSR0230P2T5G, the BAW56S-Q uniquely delivers AEC-Q101-compliant dual-channel common-anode switching in a compact 6-pin TSSOP, supporting higher VR, matched diode pairing, and true high-speed signal integrity-making it the sole fit for dual-rail automotive data interface protection.

FAQ
What is the maximum continuous forward current per diode in the BAW56S-Q?
The BAW56S-Q supports a continuous forward current of 250 mA per diode at a solder-point temperature (Ts) of 60 °C, as defined in its limiting values table. This rating assumes mounting on a standard FR4 PCB with single-sided copper and tin-plated finish. Derating applies above Ts = 60 °C, with total power dissipation limited to 350 mW per device.
Can the BAW56S-Q be used for bidirectional ESD protection on a differential pair?
Yes-the BAW56S-Q's dual common-anode configuration allows each diode pair (e.g., A1/A2–K1/K2) to clamp one side of a differential signal to VCC, while the second pair (A3/A4–K3/K4) clamps the other side. With trr ≤ 4 ns and Cd ≤ 2 pF, it preserves signal symmetry and timing margins in USB 2.0, LVDS, or MIPI D-PHY interfaces without introducing skew.
Is the BAW56S-Q pin-compatible with the legacy BAW56S?
No-the BAW56S-Q uses the SOT363-3 (TSSOP6) package with updated pinning and AEC-Q101 qualification, whereas the legacy BAW56S was packaged in SOT363 (non–"-3" variant) with different mechanical tolerances and no automotive qualification. Footprint dimensions differ slightly, and the pin 3 / pin 6 anode assignments are redefined; PCB layout revision is required.
What is the thermal resistance from junction to solder point (Rth(j-sp)) for the BAW56S-Q?
The BAW56S-Q has a typical thermal resistance of 255 K/W from junction to solder point (Rth(j-sp)), measured on an FR4 PCB with standard single-sided copper and tin-plated finish. This value enables direct thermal modeling for board-level reliability analysis and confirms suitability for operation up to 150 °C junction temperature under defined power dissipation limits.
