Product details
Overview
SMB10J11AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 11 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR at 1 mA), 18.2 V clamping voltage (VC) at 54.9 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J11AHM3/H datasheet, SMB10J11AHM3/H pinout, SMB10J11AHM3/H application, or SMB10J11AHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), junction temperature limit (TJ = 150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
The device is rated for non-repetitive 100 A forward surge current (IFSM, 8.3 ms half-sine) and derates linearly above 25 °C ambient per Figure 2. Mounting on 0.2" × 0.2" copper pads ensures thermal performance aligns with specified RθJA = 72 °C/W and maximum junction temperature of 150 °C.
Key Specifications

|---|---|
| VWM | 11 V - Maximum continuous reverse operating voltage before leakage exceeds 5 μA; defines safe DC bias margin. |
| VBR (min/max) | 12.2 V / 13.5 V at 1 mA - Breakdown onset range; ensures reliable triggering within defined tolerance band. |
| VC @ IPPM | 18.2 V at 54.9 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 1000 W - Peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| IFSM | 100 A - Single half-sine surge current rating (8.3 ms); validates robustness against inductive switch-off transients. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design boundary for PCB pad area and airflow requirements. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance (on 0.2" × 0.2" Cu pads); used to calculate steady-state temperature rise under leakage power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A-E3/52 | Same VWM/VC/PPPM, but commercial-grade (non-AEC-Q101), RoHS-compliant only (not halogen-free). | Lacks automotive qualification; suitable for industrial/commercial designs without AEC-Q101 mandate. | Select when cost sensitivity outweighs automotive qualification and halogen-free requirement. |
| SMB10J11AHE3_B/H | Identical electrical specs and AEC-Q101 qualification, but uses standard RoHS-compliant (non-halogen-free) molding compound. | Same automotive use cases; differs only in material compliance (halogen content). | Choose if halogen-free certification is not required by OEM or regional regulation (e.g., China RoHS II). |
Compared with SMB10J11AHM3/H, SMBJ11A-E3/52 offers identical clamping performance at lower cost but excludes automotive qualification and halogen-free assurance, while SMB10J11AHE3_B/H matches all electrical and qualification criteria except halogen content - making it suitable for non-halogen-restricted automotive programs.

FAQ
What is the clamping voltage of SMB10J11AHM3/H and how is it measured?
The SMB10J11AHM3/H has a maximum clamping voltage (VC) of 18.2 V, measured at a peak pulse current (IPPM) of 54.9 A using a 10/1000 µs double-exponential waveform. This value reflects the actual voltage seen by downstream circuitry during worst-case surge events and is guaranteed per the Vishay datasheet revision 09-Jan-2024 (Document Number: 88422). The SMB10J11AHM3/H maintains this clamping performance across its full operating temperature range when mounted per recommended pad layout.
Is SMB10J11AHM3/H qualified for automotive applications?
Yes, SMB10J11AHM3/H is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88422, Revision: 09-Jan-2024). The "HM3" suffix denotes halogen-free, RoHS-compliant construction with full AEC-Q101 stress test validation including HTGB, HTRB, temperature cycling, and ESD. This makes SMB10J11AHM3/H suitable for under-hood and cabin electronics where automotive-grade reliability is mandatory.
What is the difference between SMB10J11AHM3/H and SMB10J11AHE3_B/H?
The SMB10J11AHM3/H and SMB10J11AHE3_B/H share identical electrical specifications, AEC-Q101 qualification, and packaging (SMB, DO-214AA), but differ in material composition: HM3 uses halogen-free molding compound compliant with JEDEC JS709E, whereas HE3 uses standard RoHS-compliant (but halogen-containing) material. Both meet JESD201 Class 2 whisker resistance, but SMB10J11AHM3/H satisfies stricter environmental mandates such as China RoHS II and certain OEM halogen bans.
What is the thermal resistance of SMB10J11AHM3/H and how does it affect layout?
The SMB10J11AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This value assumes minimal trace length and direct thermal coupling to internal/external copper planes. To maintain TJ ≤ 150 °C under sustained leakage or repeated surges, PCB layout must replicate this pad area and avoid narrow traces that increase thermal impedance. The SMB10J11AHM3/H datasheet provides exact mounting dimensions on page 5.
Does SMB10J11AHM3/H support automated SMT placement and reflow?
Yes, SMB10J11AHM3/H is optimized for automated surface-mount assembly: it features a low-profile SMB (DO-214AA) package with matte tin-plated leads solderable per J-STD-002 and JESD22-B102, and is rated MSL Level 1 with a maximum peak reflow temperature of 260 °C per J-STD-020. No pre-baking is required, and the device withstands standard lead-free reflow profiles without delamination or parametric shift - confirmed in the official Vishay documentation for SMB10J11AHM3/H.
