Product details
Overview
SMBD7000 E6433 from Infineon Technologies is a silicon dual-switching diode array in SOT-23 package, configured as two independent high-speed switching diodes with 100 V reverse voltage rating, 200 mA forward current capability, and 4 ns reverse recovery time - used in automotive signal routing, ESD-protected I/O clamping, and fast logic-level translation circuits.
For engineers reviewing the SMBD7000 E6433 datasheet, SMBD7000 E6433 pinout, SMBD7000 E6433 application, or SMBD7000 E6433 equivalent, key selection criteria include reverse recovery time under 5 ns, low forward voltage at 10–100 mA, thermal resistance ≤360 K/W, AEC-Q101 qualification for automotive use, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual-diode array integrates two independent epitaxial planar silicon junction diodes in a single SOT-23-3 package. Each diode exhibits a maximum reverse voltage of 100 V, reverse recovery time of 4 ns at IF = IR = 10 mA, and forward voltage of 700 mV at IF = 10 mA.
The device is qualified to AEC-Q101 for automotive applications and features RoHS-compliant Pb-free packaging. Thermal resistance from junction to soldering point is ≤360 K/W, enabling reliable operation up to 150 °C junction temperature under defined PCB copper area conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports clamping and switching in 24 V automotive supply rails and 48 V subsystems |
| Forward Current (IF) | 200 mA - sufficient for logic-level signal steering and low-power interface protection |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >10 MHz digital signal paths and pulse-width modulated control lines |
| Forward Voltage (VF) | 700 mV @ 10 mA - minimizes voltage drop and power loss in bidirectional signal clamping networks |
| Junction Temperature (Tj) | 150 °C - ensures operational stability in under-hood automotive environments and industrial enclosures |
| Thermal Resistance (RthJS) | ≤360 K/W - requires minimal copper pour for thermal management on standard FR-4 PCBs |
Pinout & Package
Package: SOT-23 (3-pin, surface-mount), JEDEC TO-236AB compliant, marked "s5C" per Infineon standard marking layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Primary input node for first diode; connects to signal source requiring unidirectional conduction or clamping |
| Pin 2 | Cathode of Diode 1 / Anode of Diode 2 | Common terminal enabling dual-diode configuration - used for series-connected or center-tapped clamp topologies |
| Pin 3 | Cathode of Diode 2 | Second output node; routes clamped or switched signal to ground-referenced or rail-referenced load |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| 4 ns Reverse Recovery | Enables use in high-frequency switching nodes without signal distortion or shoot-through risk |
| RoHS-Compliant Packaging | Pb-free SOT-23 construction meets EU Directive 2011/65/EU and IPC-J-STD-020 moisture sensitivity level 1 |
| Low Capacitance (2 pF) | Minimizes loading on high-impedance signal lines such as sensor interfaces and analog comparators |
Applications
| Automotive CAN Transceiver Protection | Industrial Digital I/O Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines against ESD transients and bus fault voltages in vehicle ECUs. IC Role / Device Role / Timing Role: Dual-diode array provides bidirectional transient voltage suppression while preserving signal integrity during 1 Mbps CAN communication. Use Value: 4 ns trr prevents data corruption during fast edge transitions; 100 V VR withstands load-dump surges up to ISO 7637-2 Pulse 5a. | Use Scenario: Clamping PLC digital input channels exposed to 24 V DC field wiring with inductive kickback. IC Role / Device Role / Timing Role: Acts as fast-acting shunt limiter between input line and 5 V logic rail, diverting surge energy before MCU GPIO damage. Use Value: 200 mA IF rating handles repetitive 100 ms pulses; low VF reduces steady-state power dissipation in always-on protection circuits. |
| USB 2.0 Data Line ESD Protection | High-Speed Logic-Level Translation |
Use Scenario: Adding secondary ESD protection on D+ and D− lines downstream of integrated USB transceivers. IC Role / Device Role / Timing Role: Low-capacitance (2 pF) dual diode routes ESD current to VBUS/GND without degrading 480 Mbps eye diagram. Use Value: Sub-1 nA IR at 50 V ensures negligible leakage across hot-plug detection resistors; SOT-23 footprint fits tight USB connector spacing. | Use Scenario: Level-shifting between 3.3 V microcontroller outputs and 5 V peripheral inputs using passive diode-resistor networks. IC Role / Device Role / Timing Role: Provides matched forward characteristics for bidirectional translation in open-drain bus configurations (e.g., I²C pull-up). Use Value: Tight VF matching (±30 mV typ.) across both diodes ensures symmetrical rise/fall times; 100 mA capability supports 10 mA bus loads. |
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 |
|---|---|---|---|
| BAT54C (Diodes Inc.) | Same SOT-23 package, 30 V VR, 200 mA IF, 5 ns trr, higher IR (1 µA @ 25 V) | Limited to 24 V systems; unsuitable for 48 V automotive or industrial bus clamping | Select when lower cost and 30 V rating suffice; verify IR impact on high-impedance bias networks |
| NSR0230HT1G (ON Semi) | 30 V VR, 200 mA IF, 4 ns trr, 1.2 pF CT, but not AEC-Q101 qualified | Not approved for automotive use; lacks stress-test validation for under-hood deployment | Prefer for consumer or industrial non-automotive designs where qualification is not mandated |
Compared with BAT54C and NSR0230HT1G, SMBD7000 E6433 uniquely combines 100 V rating, AEC-Q101 qualification, and 4 ns trr - making it the only option among the three suitable for 48 V automotive signal protection without derating or system-level redesign.

FAQ
Is SMBD7000 E6433 pin-compatible with MMBD7000?
Yes - SMBD7000 E6433 and MMBD7000 share identical SOT-23 pinout (Anode1–Common–Cathode2), same marking "s5C", and identical electrical specifications per Infineon's dual-part-number release. Both are functionally interchangeable in layout and schematic design.
What is the maximum allowable continuous forward current at 105 °C ambient?
At TA = 105 °C, the maximum continuous forward current is derated to 125 mA per diode, based on the IF vs. TS curve (Fig. 4, page 3 of datasheet) and Ptot = 330 mW limit with RthJS ≤ 360 K/W and assumed TS = 28 °C.
Does SMBD7000 E6433 support bidirectional ESD protection?
No - it is a dual unidirectional diode array (not a bidirectional TVS). For bidirectional protection, external configuration (e.g., back-to-back anodes or cathodes) is required; standalone use provides unidirectional clamping from signal to VCC or GND.
Can SMBD7000 E6433 replace BAT54A in existing designs?
Only with circuit review: BAT54A is single-diode SOT-23; SMBD7000 E6433 is dual-diode with shared pin 2. Direct replacement requires verifying whether the original design uses one or both diodes and confirming pin mapping compatibility in the PCB layout.
