Product details
Overview
SMB10J10AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 17.0 V clamping voltage at 58.8 A peak pulse current, and 10 V stand-off voltage - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMB10J10AHM3_A/I datasheet, SMB10J10AHM3_A/I pinout, SMB10J10AHM3_A/I application, or SMB10J10AHM3_A/I equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity, low clamping ratio (VC/VWM = 1.7), and halogen-free RoHS compliance per HM3 suffix - critical for automotive-grade ESD/surge resilience in harsh environments.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transients induced by inductive load switching or lightning surges. Its breakdown voltage is specified at 11.1–12.3 V (IT = 1 mA), with maximum reverse leakage of 5.0 µA at 10 V stand-off.
Thermal performance is defined by RθJA = 72 °C/W and RθJL = 20 °C/W, supporting operation from –55 °C to +150 °C junction temperature. It meets MSL level 1 (260 °C reflow peak) and is qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1000 W - sustains high-energy surges without failure in automotive 12 V systems |
| Clamping Voltage VC at IPPM | 17.0 V - limits downstream IC voltage during 58.8 A transient, protecting 12 V logic |
| Stand-off Voltage VWM | 10 V - blocks normal operating voltage while remaining transparent to circuit |
| Breakdown Voltage VBR (min/max) | 11.1 V / 12.3 V - ensures reliable avalanche conduction onset above system nominal voltage |
| Maximum Reverse Leakage ID | 5.0 µA at 10 V - negligible standby current draw, preserving low-power sensor node integrity |
| Junction Temperature Range | –55 °C to +150 °C - supports under-hood automotive deployment without derating |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements (HTOL, TC, HAST, etc.) |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to protected line (e.g., battery rail); enables low VF (~3.5 V @ 50 A) during surge |
| Cathode | Current exit terminal; marked with band | Connected to ground or low-impedance return path; defines unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated pellet chip junction | Ensures stable avalanche characteristics and long-term reliability under thermal cycling |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets automotive environmental mandates without compromising surge robustness |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking, reducing manufacturing overhead |
| Excellent clamping capability (VC/VWM = 1.7) | Delivers tighter voltage limiting than typical TVS diodes, enhancing system-level immunity |
Applications
| Automotive Power Line Protection | Engine Control Unit (ECU) Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHE3_A/H | Same VWM (10 V), same SMB package, but E3 suffix (non-halogen-free, commercial grade) | Lacks AEC-Q101 qualification and halogen-free certification; unsuitable for automotive production | Select only for cost-sensitive non-automotive industrial prototypes where HM3 compliance is not required |
| SMCJ10A-HM3 | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM and clamping | Requires PCB layout change due to 2.54 mm longer body and 0.25 mm wider width | Choose when higher surge margin is needed and board space allows larger footprint |
Compared with SMB10J10AHM3_A/I, SMBJ10AHE3_A/H offers identical electrical specs but lacks automotive qualification, while SMCJ10A-HM3 delivers 50 % more surge power at the cost of larger PCB area - making SMB10J10AHM3_A/I optimal for space-constrained AEC-Q101-compliant designs.

FAQ
What is the clamping voltage of SMB10J10AHM3_A/I at its rated peak pulse current?
The SMB10J10AHM3_A/I has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 58.8 A, measured under the standard 10/1000 µs waveform. This value ensures that downstream components see no more than 17.0 V during surge events, making SMB10J10AHM3_A/I suitable for protecting 12 V automotive electronics against ISO 7637-2 transients.
Is SMB10J10AHM3_A/I qualified for automotive use?
Yes, SMB10J10AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix, indicating halogen-free, RoHS-compliant construction with automotive-grade reliability testing. The "HM3" designation confirms it meets stress requirements for temperature cycling, humidity, and high-temperature operating life - essential for under-hood and chassis-mounted applications where SMB10J10AHM3_A/I is deployed.
What does the "_A/I" suffix mean in SMB10J10AHM3_A/I?
The "_A/I" suffix in SMB10J10AHM3_A/I denotes packaging configuration: "A" indicates the revision code (per Vishay's document 88422), and "I" specifies 13-inch diameter plastic tape and reel delivery with 3200 units per reel. This matches the ordering information shown in the Vishay datasheet for SMB10J10AHM3_B/I, confirming SMB10J10AHM3_A/I is a valid, ship-ready variant with full traceability and automotive compliance.
How does SMB10J10AHM3_A/I differ from bidirectional TVS diodes like SMB8J10CA?
SMB10J10AHM3_A/I is unidirectional with cathode marking and forward conduction capability (VF ≈ 3.5 V @ 50 A), whereas SMB8J10CA is bidirectional and symmetrical. SMB10J10AHM3_A/I provides superior surge handling (1000 W vs. 800 W) and lower clamping voltage in DC-biased applications - making SMB10J10AHM3_A/I preferred for power rail protection, while SMB8J10CA suits AC-coupled or differential signal lines.
What is the thermal resistance of SMB10J10AHM3_A/I, and how does it affect layout design?
SMB10J10AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation at full 1000 W surge rating, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - a requirement explicitly stated in the Vishay datasheet for SMB10J10AHM3_A/I and critical to avoid thermal runaway during repeated transients.
