Product details
Overview
BAW56WE6433 from Nexperia is a silicon double diode in common-anode configuration housed in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time - optimized for high-speed switching in signal routing and ESD protection circuits in automotive infotainment and industrial I/O modules.
For engineers reviewing the BAW56WE6433 datasheet, BAW56WE6433 pinout, BAW56WE6433 application, or BAW56WE6433 equivalent, this dual switching diode supports fast transient response, low capacitance (2 pF), and AEC-Q101 qualification - critical for CAN bus interface protection, RF antenna switching, and logic-level clamping in space-constrained PCBs.
Technical Context
The BAW56WE6433 integrates two identical epitaxial planar diodes sharing a common anode terminal, enabling bidirectional clamping or dual-path switching without external interconnect. Its 2 pF junction capacitance at 0 V and 4 ns trr support >100 MHz signal integrity in RF front-end switching.
Thermal design is enabled by RthJS = 240 K/W (SC74 package), with maximum junction temperature of 150 °C and guaranteed operation up to 125 °C ambient - validated per AEC-Q101 stress testing including HTGB, HTRB, and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transients with 3× safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 100+ MHz digital clock distribution and RF antenna tuning |
| Junction Capacitance (CT) | 2 pF @ 0 V, 1 MHz - minimizes signal loading in high-impedance analog sensor interfaces |
| Forward Voltage (VF) | 1.25 V @ 150 mA - ensures low conduction loss in active clamping paths |
| Thermal Resistance (RthJS) | 240 K/W - allows 250 mW power dissipation with ≤60 °C junction-to-solder-point rise at 100% DC load |
| AEC-Q101 Qualified | Yes - qualified for automotive-grade reliability including HTGB, HTRB, and ESD (HBM ≥8 kV) |
Pinout & Package
BAW56WE6433 uses the SC74 (SOT-363) surface-mount package: 6-pin, 2.9 mm × 1.9 mm footprint, 1.1 mm max height, with pin 1 marked by dot or bevel. Common-anode topology places Anode (A) on Pin 5; Diode 1 cathode (K1) on Pin 1; Diode 2 cathode (K2) on Pin 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Diode 1 | Signal path output for first switching leg; routed to protected I/O line |
| Pin 2 | No Connection | Internally unconnected; must remain floating or grounded per layout guidelines |
| Pin 3 | Cathode of Diode 2 | Independent signal path output for second switching leg or redundancy path |
| Pin 4 | No Connection | Internally unconnected; no PCB trace required |
| Pin 5 | Common Anode | Shared input node for both diodes; connects to bias rail or pull-up source |
| Pin 6 | No Connection | Internally unconnected; leave unpopulated or tie to ground only if thermal relief needed |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 4 ns trr enables use in 100–500 MHz RF switch applications without signal distortion |
| Low junction capacitance | 2 pF at 0 V reduces insertion loss in 50 Ω transmission lines by <0.2 dB at 2.4 GHz |
| AEC-Q101 qualification | Validated for automotive under-hood environments: -40 °C to +125 °C continuous operation |
| Common-anode dual-diode topology | Eliminates need for external anode tie; saves 2.5 mm² board area vs. discrete SOT-23 pair |
Applications

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,115 | Same SC74 package, but 100 V VR and 6 ns trr; VF = 1.25 V @ 150 mA identical | Higher VR supports 48 V industrial buses; slower trr limits use to ≤50 MHz signals | Select when higher reverse standoff is prioritized over RF speed |
| PMEG3005AESF,115 | Lower VF (0.45 V @ 100 mA), Schottky architecture, 30 V VR, 1.5 pF CT | Not AEC-Q101 qualified; unsuitable for automotive; better for low-VF logic clamping | Select only for non-automotive, low-voltage (<5 V) clamping where leakage tolerance >1 µA |
Compared with BAV99W and PMEG3005AESF, BAW56WE6433 uniquely balances AEC-Q101 compliance, 4 ns speed, and 80 V robustness - making it the only choice for automotive CAN FD protection and 2.4 GHz antenna switching where all three attributes are simultaneously required.

FAQ
What is the pin 1 marking convention for BAW56WE6433?
Pin 1 is identified by a small dot or beveled edge located at the top-left corner of the SC74 package when viewed from the top with the marking side up and the tab oriented downward. The pin numbering follows standard SOT-363 sequence: Pin 1 (top-left), Pin 2 (top-center), Pin 3 (top-right), Pin 4 (bottom-right), Pin 5 (bottom-center), Pin 6 (bottom-left).
Is BAW56WE6433 suitable for bidirectional ESD protection?
Yes - its common-anode dual-diode structure supports symmetrical clamping when paired with external pull-down resistors on each cathode. With 8 kV HBM ESD rating and 4 ns response, it meets IEC 61000-4-2 Level 4 requirements for CAN and USB interface protection when implemented per Nexperia Application Note AN10782.
How does thermal performance differ between BAW56WE6433 and single-diode SOT-23 equivalents?
BAW56WE6433's SC74 package delivers RthJS = 240 K/W - 20% lower than typical SOT-23 dual-diode alternatives - due to larger copper paddle area and dual thermal paths. This allows 250 mW total dissipation at TS ≤ 90 °C, versus ≤180 mW for comparable SOT-23 duals under identical board conditions.
Can BAW56WE6433 replace BAW56S in existing designs?
Yes, with verification of thermal margin: both share identical electrical specs and SC74 footprint, but BAW56WE6433 has TS ≤ 90 °C derating (same as BAW56S), whereas BAW56S datasheet specifies TS ≤ 85 °C. Layout and soldering profile require no change; confirm junction temperature remains ≤150 °C using measured board temperatures.
