Product details
Overview
SMB10J16AHM3_B/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 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) rating under 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gate drivers, and microcontroller I/O interfaces against inductive switching transients.
For engineers reviewing the SMB10J16AHM3_B/H datasheet, SMB10J16AHM3_B/H pinout, SMB10J16AHM3_B/H application, or SMB10J16AHM3_B/H equivalent, key selection criteria include clamping performance at rated surge current, AEC-Q101 qualification status, unidirectional polarity configuration, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltage before damage occurs. Its breakdown voltage (VBR) is specified at 17.8–19.7 V with 1.0 mA test current, ensuring precise triggering above system operating voltage while maintaining low leakage (<1.0 µA at 16 V).
The SMB10J16AHM3_B/H uses a unidirectional configuration with cathode band marking, supports 100 A non-repetitive forward surge current (IFSM), and is rated for junction temperatures from –55 °C to +150 °C. It meets MSL level 1 per J-STD-020 and is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown voltage range at 1.0 mA; ensures reliable turn-on margin above VWM with process tolerance. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamping voltage during 10/1000 µs surge; defines worst-case overvoltage seen by protected IC. |
| PPPM | 1000 W - Peak pulse power handling capability; determines survivability against standardized lightning/surge events. |
| ID @ VWM | <1.0 µA - Reverse leakage at stand-off voltage; critical for low-power sensor and battery-backed circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables use in high-ambient automotive engine compartments. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs board-level thermal design. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHE3_A/H | Same VWM (16 V), VC (26.0 V), and PPPM (1000 W); differs in packaging code (E3 vs HM3) and revision suffix (A/H vs B/H). | Commercial-grade variant without halogen-free certification; suitable for non-automotive industrial use where AEC-Q101 not required. | Select when halogen-free compliance is not mandated and cost optimization is prioritized over automotive qualification. |
| 1.5SMC16A | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs 72 °C/W; higher IFSM (200 A). | Better thermal performance and surge margin, but requires 30% larger PCB area; not drop-in compatible with SMB footprints. | Choose when board layout allows larger package and higher thermal robustness is needed for repeated surge exposure. |
Compared with SMBJ16AHE3_A/H and 1.5SMC16A, SMB10J16AHM3_B/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint-making it optimal for space-constrained automotive electronics where regulatory compliance and reliability are non-negotiable.

FAQ
What is the clamping voltage of SMB10J16AHM3_B/H at its rated peak pulse current?
The SMB10J16AHM3_B/H has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 38.5 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected downstream components will not experience voltages exceeding 26.0 V during defined surge events, making SMB10J16AHM3_B/H suitable for safeguarding 3.3 V and 5 V logic interfaces.
Is SMB10J16AHM3_B/H qualified for automotive applications?
Yes, SMB10J16AHM3_B/H is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88422 (Revision 09-Jan-2024). The "HM3" suffix denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock-ensuring reliability in under-hood automotive environments where SMB10J16AHM3_B/H is deployed for sensor and ECU protection.
What does the "B/H" suffix mean in SMB10J16AHM3_B/H?
The "B/H" suffix in SMB10J16AHM3_B/H indicates the packaging configuration: "B" denotes tape-and-reel delivery on a 7-inch diameter reel, and "H" specifies the preferred package code per Vishay's ordering nomenclature. This matches the documented preferred P/N SMB10J16AHM3_B/H in the Ordering Information table (page 3 of doc 88422), confirming 750-unit reel quantity and halogen-free AEC-Q101 compliance-critical for traceability and production planning.
How does SMB10J16AHM3_B/H differ from bidirectional variants like SMB8J16CA?
SMB10J16AHM3_B/H is unidirectional with cathode band marking and 100 A IFSM rating, whereas SMB8J16CA is bidirectional with no polarity marking and lower PPPM (800 W vs 1000 W). SMB10J16AHM3_B/H provides superior surge handling for DC-biased lines (e.g., power rails, sensor outputs), while SMB8J16CA suits AC-coupled or symmetrical signal paths. Their VWM and VC values differ slightly due to internal structure-SMB10J16AHM3_B/H clamps at 26.0 V, SMB8J16CA at same VC but with dual-quadrant conduction.
What is the thermal resistance of SMB10J16AHM3_B/H, and how does it affect PCB layout?
SMB10J16AHM3_B/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 Thermal Characteristics table. This value assumes minimum recommended pad layout; reducing pad size increases RθJA and risks thermal runaway during repeated surges. Designers must allocate adequate copper area and consider thermal vias if ambient temperature exceeds 85 °C or surge duty cycle is high-ensuring SMB10J16AHM3_B/H remains within its 150 °C TJ max rating.
