Product details
Overview
SMB10J16AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection of DC power rails and signal lines. It features a 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 (10/1000 µs waveform), making it suitable for automotive power supply rail protection per AEC-Q101.
For engineers reviewing the SMB10J16AHM3/I datasheet, SMB10J16AHM3/I pinout, SMB10J16AHM3/I application, or SMB10J16AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS compliance (HM3 suffix), 150 °C max junction temperature, and verified clamping performance under 10/1000 µs transients - critical for robust ESD and load-dump immunity in automotive ECUs and industrial controllers.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for low incremental surge resistance and fast response (<1 ns), enabling effective suppression of fast-rising transients from inductive switching and ISO 7637-2 load dump events. Its unidirectional polarity and cathode-band marking align with standard PCB layout conventions for DC rail protection.
The device operates within -55 °C to +150 °C junction temperature range and exhibits 1.0 µA maximum reverse leakage at VWM, ensuring minimal standby power loss. Thermal resistance is specified at RθJA = 72 °C/W (on 0.2" × 0.2" copper pads), supporting reliable thermal management in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous DC operating voltage before conduction begins; sets upper limit for protected circuit's nominal rail voltage. |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - Breakdown threshold range ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamping voltage during 1000 W surge defines worst-case overvoltage seen by downstream ICs. |
| IPPM | 38.5 A (10/1000 µs) - Peak surge current handling capacity directly supports ISO 16750-2 Pulse 5a load-dump immunity up to 12 V systems. |
| PPPM | 1000 W - Peak pulse power rating confirms suitability for high-energy transients without thermal runaway under defined test conditions. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and sealed industrial enclosures without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including stress testing for temperature cycling, HTRB, and mechanical shock. |

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 | Same VWM (16 V), VC = 26.0 V, but rated for 600 W (not 1000 W); RoHS-compliant (E3), not halogen-free. | Lacks AEC-Q101 qualification and halogen-free construction; suitable only for commercial-grade non-automotive use. | Select when cost sensitivity outweighs automotive qualification and higher surge margin requirements. |
| 1.5SMC16A | Same VWM (16 V), VC = 26.0 V, 1000 W rating, but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm). | Requires larger PCB footprint and different pad layout; thermal resistance RθJA = 40 °C/W (vs. 72 °C/W for SMB). | Choose when higher thermal dissipation is needed and board space permits larger package. |

The SMB10J16AHM3/I has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPPM) of 38.5 A under the standardized 10/1000 µs waveform. This value is measured and guaranteed per Vishay's datasheet (Document Number: 88422, Revision: 09-Jan-2024), ensuring predictable overvoltage limiting for protected circuits during surge events.
Is SMB10J16AHM3/I qualified for automotive applications?
Yes, SMB10J16AHM3/I is AEC-Q101 qualified, as confirmed by Vishay's official documentation. The HM3 suffix denotes halogen-free, RoHS-compliant construction with automotive-grade reliability validation, including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock testing - making SMB10J16AHM3/I suitable for under-hood and chassis-mounted automotive electronics.
What does the "HM3/I" suffix mean in SMB10J16AHM3/I?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance; "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This configuration ensures compatibility with high-speed automated placement equipment and meets stringent environmental and manufacturing requirements for automotive production.
How does SMB10J16AHM3/I differ from SMBJ16A in terms of surge capability?
SMB10J16AHM3/I delivers 1000 W peak pulse power (10/1000 µs), whereas SMBJ16A is rated for 600 W. Both share identical VWM (16 V) and VC (26.0 V), but SMB10J16AHM3/I supports 38.5 A IPPM vs. 24.7 A for SMBJ16A - providing 56% higher surge current handling and superior resilience against severe load-dump events in 12 V automotive systems.
What is the maximum operating junction temperature for SMB10J16AHM3/I?
The SMB10J16AHM3/I has a maximum operating junction temperature (TJ) of +150 °C, as specified in Vishay's datasheet.
