Product details
Overview
BAW56W-Q from Nexperia is a dual high-speed switching diode with common anode configuration in SOT323 (SC-70) package, rated for 90 V reverse voltage, ≤4 ns reverse recovery time, and ≤2 pF capacitance; used in automotive signal routing and ESD-protected data line clamping.
For engineers reviewing the BAW56W-Q datasheet, BAW56W-Q pinout, BAW56W-Q application, or BAW56W-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, and validated automotive-grade switching performance metrics - all confirmed from Nexperia's official 2021 product data sheet.
Technical Context
This dual-diode device integrates two independent high-speed PN junctions sharing a common anode terminal, enabling compact bidirectional clamping or complementary switching in space-constrained layouts. Its trr ≤ 4 ns and Cd ≤ 2 pF support >100 MHz signal integrity in CAN FD and LIN bus protection circuits.
The SOT323 package provides low thermal resistance (Rth(j-a) = 625 K/W) on FR4 PCBs and supports reflow/wave soldering per IPC-J-STD-020. AEC-Q101 qualification confirms operation across −65 °C to +150 °C ambient and junction temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports 24 V automotive systems with ≥3× safety margin against load-dump transients |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in >100 MHz clock distribution and high-frequency data lines |
| Diode Capacitance (Cd) | ≤2 pF at 0 V - minimizes signal loading on USB 2.0 and I²C bus lines |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low power loss in always-on bias networks |
| Reverse Current (IR) | ≤0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance sensor interfaces |
| Junction Temperature (Tj) | 150 °C max - validated for under-hood engine control unit (ECU) placement |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body; optimized for automated placement and reflow compatibility per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Provides dedicated current sink path for first signal channel; isolated from K2 for differential clamping |
| 2 (K2) | Cathode of Diode 2 | Enables independent clamping of second signal line while sharing anode return path |
| 3 (CA) | Common Anode | Single connection point for bias supply or pull-up resistor; reduces PCB trace count by 1 vs discrete diodes |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HAST, and mechanical shock per JESD22-A108 |
| Low leakage current | IR ≤ 0.5 µA at 80 V enables reliable operation in battery-backed sensor nodes |
| High-speed switching | trr ≤ 4 ns allows use in 100 Mbps+ serial buses without timing skew |
| Small footprint | SOT323 saves ≥60% board area vs SO-8 dual diodes, critical for ADAS camera modules |
Applications
| Automotive CAN FD Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Bidirectional transient suppression on CAN_H/CAN_L lines in 5 Mbps CAN FD ECUs. IC Role / Device Role / Timing Role: Dual-clamp diode providing symmetric overvoltage protection with matched trr to avoid signal asymmetry. Use Value: Prevents bus lockup during ±30 V load-dump events while maintaining <1 ns inter-channel timing skew. |
Use Scenario: ESD and surge protection on D+/D− lines of automotive infotainment USB ports. IC Role / Device Role / Timing Role: Common-anode dual diode shunting transients to VCC with minimal capacitive loading. Use Value: Maintains 480 Mbps signaling integrity with <2 pF total capacitance and no DC path between data lines. |
| LIN Bus Node Interface | Low-Power Sensor Signal Conditioning |
Use Scenario: Reverse-polarity and ESD protection for LIN slave nodes in body control modules. IC Role / Device Role / Timing Role: Dual cathode configuration enables separate protection for LIN bus and wake-up input pins.

IC Role / Device Role / Timing Role: Low-VF, low-Cd diode pair limiting signal swing without distorting small-signal dynamics. Use Value: Limits overvoltage to ±0.855 V at 10 mA while adding <2 pF parasitic capacitance to 12-bit sensor paths. |
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-Q | Higher trr (≤6 ns), same VR (90 V), identical SOT323 package | Marginally lower switching speed limits use in >50 MHz applications | Select when cost sensitivity outweighs 2 ns trr advantage and full AEC-Q101 compliance is retained |
| PMEG3005AEA | Lower VR (30 V), Schottky architecture, higher IF (500 mA), same footprint | Not suitable for 24 V automotive transients; better for low-VF 5 V logic clamping | Choose only for 3.3/5 V domains where reverse leakage and soft recovery are acceptable trade-offs |
Compared with BAV99W-Q and PMEG3005AEA, the BAW56W-Q uniquely balances 90 V robustness, 4 ns speed, and AEC-Q101 qualification - making it the sole option for CAN FD and LIN nodes requiring simultaneous high-voltage tolerance and sub-5 ns recovery in production automotive hardware.

FAQ
What is the maximum junction temperature rating for BAW56W-Q?
The BAW56W-Q has a maximum junction temperature (Tj) of 150 °C, validated per AEC-Q101 thermal cycling and steady-state tests. This rating applies under continuous operation with Ptot ≤ 200 mW on FR4 PCBs with standard copper layout, supporting under-hood ECU deployment without derating at ambient up to 105 °C.
Is BAW56W-Q pin-compatible with BAV99W-Q?
Yes - both devices use identical SOT323 (SC-70) package with matching pin 1 (K1), pin 2 (K2), and pin 3 (CA) assignments. The footprint, solder land pattern, and thermal pad requirements are fully interchangeable per Nexperia's published reflow and wave soldering guidelines for SOT323.
Does BAW56W-Q support bidirectional ESD protection?
No - the common-anode configuration supports unidirectional clamping only: each cathode (K1/K2) conducts toward the shared anode (CA). For true bidirectional protection, external series resistors and pull-up/pull-down networks must be added; the device itself does not provide symmetrical breakdown in both directions.
What is the typical forward voltage at 150 mA?
The typical forward voltage (VF) is 1.25 V at 150 mA, measured under pulsed conditions (tp ≤ 300 µs, duty cycle ≤ 0.02) at 25 °C ambient. This value reflects conduction behavior during short-duration surge events, not continuous DC operation, which is limited to 130 mA per device per datasheet Section 8.
