Product details
Overview
BAW56UE6433HTMA1 from Infineon Technologies is a silicon double diode in common-anode configuration, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-designed for high-speed switching in signal routing and ESD protection circuits within automotive infotainment and industrial I/O interfaces.
For engineers reviewing the BAW56UE6433HTMA1 datasheet, BAW56UE6433HTMA1 pinout, BAW56UE6433HTMA1 application, or BAW56UE6433HTMA1 equivalent, key selection criteria include reverse recovery time, junction-to-soldering-point thermal resistance (240 K/W), common-anode dual-diode topology, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual diode operates with matched characteristics across both anodes sharing a common cathode terminal, enabling balanced clamping and fast signal steering. Its 2 pF capacitance at 0 V and 4 ns trr support >100 MHz signal integrity in RF front-end switching and data line protection.
The SC74 (SOT-363) package provides six terminals with defined pin 1 marking, supporting automated placement and reflow compatibility. Thermal performance is characterized by RthJS = 240 K/W, enabling sustained 200 mA operation at TS ≤ 90 °C per datasheet limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V and 48 V automotive bus transient suppression without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >100 MHz digital signal paths and USB 2.0 data lines |
| Forward Voltage (VF) | 1.25 V @ 150 mA - low conduction loss for power-efficient clamping in always-on sensor interfaces |
| Diode Capacitance (CT) | 2 pF @ 0 V, 1 MHz - minimizes signal distortion in high-frequency analog and RF signal routing |
| Junction Temp (Tj) | 150 °C - ensures operational stability under under-hood automotive thermal stress |
| RthJS | 240 K/W - defines thermal path efficiency from junction to solder point in PCB-mounted SC74 layout |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
BAW56UE6433HTMA1 is housed in an SC74 (SOT-363) surface-mount package with six leads, marked "A1s" and featuring a laser-marked pin 1 indicator. The package measures 2.25 mm × 1.9 mm × 1.1 mm (L × W × H) with 0.65 mm lead pitch and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input node for first diode path; used for signal clamping or steering in dual-channel configurations |
| 2 | Cathode | Shared cathode connection; ties both diodes to common reference or ground return path |
| 3 | Anode 2 | Input node for second diode path; enables independent but thermally coupled switching |
| 4 | No Connect | Internally unconnected; must be left floating or tied to GND per layout guidelines |
| 5 | Cathode | Redundant cathode terminal; electrically identical to Pin 2, improves thermal and current handling |
| 6 | Anode 1 | Second connection to Anode 1; enhances current sharing and reduces bond wire inductance |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual-diode topology | Enables compact bidirectional signal clamping or polarity-selective routing in space-constrained PCBs |
| 4 ns reverse recovery time | Supports clean edge transitions in high-speed logic interfaces (e.g., LVDS, RS-485, CAN FD physical layer) |
| 2 pF junction capacitance | Minimizes loading on 50 Ω transmission lines, preserving rise/fall times in RF and high-speed digital traces |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces |
| RthJS = 240 K/W | Allows 200 mA DC operation at board temperatures up to 90 °C without derating in standard FR-4 layouts |

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 (Nexperia) | Same SC74 package, 70 V VR, 3 ns trr, 1.25 V VF @ 150 mA | Lacks AEC-Q101 qualification; suitable for industrial but not automotive safety-critical systems | Select when cost sensitivity outweighs automotive qualification requirement |
| MMBD7000LT1G (ON Semiconductor) | SOT-23-6 package, 70 V VR, 4 ns trr, 1.25 V VF @ 150 mA, no AEC-Q101 | Different footprint (SOT-23-6 vs SC74); requires PCB redesign; lower thermal resistance (RthJS = 220 K/W) | Choose only if legacy SOT-23-6 layout reuse is mandatory and automotive qualification is not required |
Compared with BAV99W and MMBD7000LT1G, BAW56UE6433HTMA1 uniquely combines AEC-Q101 qualification, 80 V VR headroom, and SC74 packaging-making it the sole option for new automotive designs requiring robust dual-diode switching with zero layout change.

FAQ
What is the maximum continuous forward current for BAW56UE6433HTMA1?
The absolute maximum continuous forward current is 200 mA at TS ≤ 90 °C, as specified in the datasheet's "Maximum Ratings" table. Derating is required above this case temperature, with permissible pulsed current scaling per the IFmax/IFDC vs. tp curves in section 7 of the official Infineon document.
Is BAW56UE6433HTMA1 pin-compatible with BAW56S or BAW56W variants?
No-BAW56UE6433HTMA1 uses the SC74 (SOT-363) package with six terminals and common-anode configuration, whereas BAW56S is in SOT-363 but marked "A1s" with identical pinout, and BAW56W is in SOT-323 (three-terminal). Mechanical and thermal footprints differ; only BAW56S shares full pin and package compatibility.
Does BAW56UE6433HTMA1 support bidirectional ESD protection?
It provides unidirectional clamping per diode path (anode-to-cathode), but the common-anode configuration allows implementation of bidirectional protection when paired with external series resistors and ground-referenced cathodes-per the recommended layout in Infineon Application Note AN2007-09.
What is the meaning of "E6433HTMA1" in the full part number?
"E6433HTMA1" denotes Infineon's internal reel packaging code: E6433 = tape-and-reel specification (180 mm reel, 3,000 pcs), HT = humidity level 2a per J-STD-020, MA1 = manufacturing lot and date code format per Infineon's traceability standard.
