Product details
Overview
SMB10J16AHM3_B/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features 16 V stand-off voltage (VWM), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs and industrial sensor interfaces to safeguard MOSFETs and microcontrollers against inductive switching transients.
For engineers reviewing the SMB10J16AHM3_B/I datasheet, SMB10J16AHM3_B/I pinout, SMB10J16AHM3_B/I application, or SMB10J16AHM3_B/I equivalent, key selection criteria include clamping performance under 100 A IFSM surge, AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging an avalanche breakdown mechanism to limit transient voltages before they damage downstream ICs. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, while the SMB package supports high thermal dissipation with RθJL = 20 °C/W.
The device is rated for -55 °C to +150 °C operating junction temperature and meets MSL level 1 per J-STD-020 with 260 °C reflow peak. It is halogen-free, RoHS-compliant, and AEC-Q101 qualified - confirming suitability for automotive-grade power rail and CAN/LIN bus line protection where reliability under repeated surge stress is critical.

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); commercial-grade (non-AEC-Q101), RoHS-compliant only | Lacks automotive qualification; suitable for industrial/commercial power supplies but not safety-critical automotive systems | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC16A | Same VWM and VC, but larger SMC (DO-214AB) package; higher RθJA (50 °C/W vs. 72 °C/W), lower mounting density | Requires larger PCB area and different pad layout; less suitable for high-density automotive modules | Choose only if legacy SMC footprint compatibility is mandatory and thermal derating allows |

FAQ
What is the clamping voltage of SMB10J16AHM3_B/I at its rated peak pulse current?
The SMB10J16AHM3_B/I has a maximum clamping voltage (VC) of 26.0 V when subjected to its specified peak pulse current (IPPM) of 38.5 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 3.3 V, 5 V, and 12 V ICs downstream of the SMB10J16AHM3_B/I.
Is SMB10J16AHM3_B/I qualified for automotive applications?
Yes, SMB10J16AHM3_B/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HM3_B/I", where "H" denotes AEC-Q101 qualification and "M3" indicates halogen-free, RoHS-compliant construction. This certification validates its reliability for use in automotive powertrain, chassis, and body electronics where sustained operation at 150 °C junction temperature and resistance to mechanical shock/vibration are required.
What does the "HM3_B/I" suffix mean in SMB10J16AHM3_B/I?
The "HM3_B/I" suffix in SMB10J16AHM3_B/I identifies the product variant: "H" confirms AEC-Q101 qualification; "M3" specifies halogen-free and RoHS-compliant materials; "B" denotes the revision level; and "I" indicates packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix ensures traceability to manufacturing lot, environmental compliance, and logistics configuration - essential for automotive Tier 1 procurement and PPAP documentation.
Can SMB10J16AHM3_B/I be used in bidirectional configurations?
No, SMB10J16AHM3_B/I is a unidirectional TVS diode, as indicated by its part number structure (no "C" in the base designation) and explicit listing in the unidirectional table of Vishay's datasheet 88422. Bidirectional variants carry "CA" suffixes (e.g., SMB8J16CA). Using SMB10J16AHM3_B/I in bidirectional circuits would result in unintended forward conduction during negative transients - select SMB8J16CAHM3_B/I instead for symmetrical protection.
What is the thermal resistance from junction to ambient for SMB10J16AHM3_B/I?
The typical thermal resistance from junction to ambient (RθJA) for SMB10J16AHM3_B/I is 72 °C/W, measured on a standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per terminal. This value assumes FR-4 PCB with no internal planes; actual thermal performance improves significantly with additional copper pour or thermal vias - important for sustaining repetitive surge duty cycles in high-temperature environments where SMB10J16AHM3_B/I operates.
