Product details
Overview
SMB10J7.0AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 7.0 V stand-off voltage, 12.0 V clamping voltage at 200 A peak pulse current, and 1000 W peak pulse power rating under 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and microcontroller I/O pins against inductive switching transients.
For engineers reviewing the SMB10J7.0AHM3_A/H datasheet, SMB10J7.0AHM3_A/H pinout, SMB10J7.0AHM3_A/H application, or SMB10J7.0AHM3_A/H equivalent, key selection criteria include clamping performance at rated surge current, AEC-Q101 qualification status, unidirectional polarity, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its breakdown voltage range (7.78–8.60 V at 10 mA) ensures reliable turn-on before sensitive downstream circuitry reaches damage thresholds.
The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine) and supports operation from –55 °C to +150 °C junction temperature. Its MSL Level 1 rating and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum reverse working voltage before leakage exceeds 100 μA; defines safe operating margin below breakdown. |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - Ensures consistent turn-on across production lot; guarantees clamping initiates within defined voltage band. |
| VC @ IPPM | 12.0 V at 200 A - Clamping voltage during full-rated 10/1000 µs surge; limits stress on protected ICs to safe levels. |
| PPPM | 1000 W - Peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a surges in automotive systems. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs board-level thermal design for sustained surge duty. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive deployment with minimal derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0AHE3_A/H | Same electrical specs, but uses E3 suffix (RoHS-compliant commercial grade, not AEC-Q101 qualified). | Lacks automotive qualification; unsuitable for safety-critical vehicle subsystems. | Select when cost-sensitive industrial or consumer designs do not require AEC-Q101 validation. |
| SMB10J7.0A-M3/5B | Identical TVS parameters, halogen-free RoHS compliance, but packaged in 13" tape (3200 pcs) and lacks AEC-Q101 certification. | No automotive qualification; different packaging format affects inventory planning and SMT feeder setup. | Choose for high-volume commercial production where halogen-free compliance is mandatory but automotive qualification is unnecessary. |
Compared with SMBJ7.0AHE3_A/H and SMB10J7.0A-M3/5B, the SMB10J7.0AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and 1000 W surge capability in SMB package-making it the only option qualified for under-hood automotive signal line protection without layout or BOM change.

FAQ
What is the clamping voltage of SMB10J7.0AHM3_A/H at its rated peak pulse current?
The SMB10J7.0AHM3_A/H has a maximum clamping voltage (VC) of 12.0 V at 200 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains below critical overvoltage thresholds during surge events. The SMB10J7.0AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is SMB10J7.0AHM3_A/H qualified for automotive applications?
Yes, SMB10J7.0AHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 88422 datasheet. It undergoes stress testing including high-temperature operating life, temperature cycling, and unbiased HAST to meet automotive reliability standards. The SMB10J7.0AHM3_A/H is approved for use in engine control units, body electronics, and ADAS sensor modules.
What is the standoff voltage rating for SMB10J7.0AHM3_A/H?
The standoff voltage (VWM) of SMB10J7.0AHM3_A/H is 7.0 V - the maximum DC or continuous reverse voltage the device can withstand without exceeding 100 μA leakage current. This rating ensures reliable blocking during normal operation while allowing fast avalanche turn-on when transients exceed the breakdown threshold. The SMB10J7.0AHM3_A/H's VWM aligns with 5 V and 3.3 V logic interface protection requirements.
Does SMB10J7.0AHM3_A/H have a bidirectional variant?
No, SMB10J7.0AHM3_A/H is strictly unidirectional. Bidirectional variants in the same family carry "C" in the part number (e.g., SMB8J7.0CA), but those use the SMB8J series and differ in peak pulse power (800 W vs. 1000 W) and surge current rating. The SMB10J7.0AHM3_A/H is optimized for ground-referenced clamping and must be oriented with cathode toward the protected line.
What package type does SMB10J7.0AHM3_A/H use, and what are its mounting requirements?
SMB10J7.0AHM3_A/H uses the SMB (DO-214AA) surface-mount package with standardized dimensions: 4.57 mm × 3.94 mm × 2.20 mm. It requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 1000 W pulse dissipation. The SMB10J7.0AHM3_A/H meets MSL Level 1 and supports lead-free reflow up to 260 °C peak temperature without preconditioning.
