Product details
Overview
SMB10J10AHM3/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 a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 5.0 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMB10J10AHM3/I datasheet, SMB10J10AHM3/I pinout, SMB10J10AHM3/I application, or SMB10J10AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, 11.1–12.3 V breakdown voltage range at 1 mA test current, and low 1.0 µA reverse leakage at VWM - critical for low-power automotive electronics requiring long-term reliability under thermal stress.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR over temperature and lifetime, while low incremental surge resistance enables rapid energy diversion during 8.3 ms half-sine surges up to 100 A (IFSM).
The SMB10J10AHM3/I is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its bidirectional counterpart (e.g., SMB8J10CA) offers higher IPPM but lower PPPM - confirming SMB10J10AHM3/I's design focus on unidirectional high-power surge handling in constrained PCB space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V automotive systems. |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - tight breakdown tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 17.0 V at 5.0 A - clamping voltage limits downstream IC stress during 10/1000 µs transients; supports 3.3 V/5 V logic protection. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 µs waveform; enables robust protection against ISO 7637-2 Pulse 1/2/5a events. |
| ID @ VWM | 1.0 µA - ultra-low reverse leakage preserves battery life in always-on automotive modules like body control units. |
| TJ max | +150 °C - extended junction temperature rating supports under-hood deployment without derating in engine control units. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to ground or low-side return; conducts during forward surge (e.g., reverse polarity protection). |
| Cathode | Clamping node | Connected to protected line; conducts avalanche current when transient exceeds VBR, shunting energy to ground. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J10AHE3/I | Same electrical specs; RoHS-compliant but not halogen-free; lacks JESD201 Class 2 whisker resistance. | Approved for commercial/industrial use only; not AEC-Q101 certified for automotive under-hood placement. | Select when halogen-free requirement is waived and cost sensitivity outweighs automotive qualification needs. |
| SMBJ10A-T | Identical VWM/VBR/VC/PPPM; same SMB package; manufactured by Diodes Inc.; no AEC-Q101 documentation publicly available. | Used in industrial power supplies and telecom equipment; not validated for automotive temperature cycling or humidity testing. | Choose for non-automotive designs where second-source availability and distributor stock depth are prioritized. |
Compared with SMB10J10AHM3/I, SMB10J10AHE3/I omits halogen-free compliance and automotive qualification, while SMBJ10A-T provides functional equivalence without documented AEC-Q101 validation - making SMB10J10AHM3/I the sole choice for safety-critical automotive deployments requiring full specification traceability.

FAQ
What is the breakdown voltage range of SMB10J10AHM3/I at 1 mA test current?
The SMB10J10AHM3/I has a guaranteed breakdown voltage (VBR) range of 11.1 V to 12.3 V when measured at IT = 1 mA, per Vishay Document Number 88422. This tight tolerance ensures consistent clamping behavior across temperature and production batches, directly supporting reliable protection of 12 V automotive subsystems. The SMB10J10AHM3/I maintains this specification under -55 °C to +150 °C operating conditions.
Is SMB10J10AHM3/I suitable for automotive applications?
Yes, SMB10J10AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance. It is explicitly rated for automotive use in engine control units, body electronics, and ADAS sensor modules. The SMB10J10AHM3/I meets MSL Level 1 and supports lead-free reflow up to 260 °C, fulfilling critical manufacturing and reliability requirements for automotive production.
What is the maximum clamping voltage of SMB10J10AHM3/I and at what current is it specified?
The SMB10J10AHM3/I has a maximum clamping voltage (VC) of 17.0 V, specified at a peak pulse current (IPPM) of 5.0 A using the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and confirms compatibility with 5 V and 3.3 V logic interfaces. The SMB10J10AHM3/I achieves this clamping performance while maintaining low incremental resistance for minimal overshoot.
Does SMB10J10AHM3/I have a bidirectional variant?
No - SMB10J10AHM3/I is strictly unidirectional. Its marking code "1AX" and data sheet designation confirm cathode-band polarity and single-direction avalanche conduction. For bidirectional protection at 10 V standoff, Vishay offers SMB8J10CA (800 W PPPM, 17.0 V VC at 10 A), which shares identical VWM and VC but differs in surge current capability and qualification status. The SMB10J10AHM3/I is not interchangeable with bidirectional variants due to fundamental polarity and test waveform differences.
What packaging and reel options are available for SMB10J10AHM3/I?
SMB10J10AHM3/I is supplied in 13-inch plastic tape and reel format with base quantity 3200 units per reel (package code "I"). The part uses embossed carrier tape compatible with automated SMT placement equipment. Lead finish is matte tin, qualified per J-STD-002, and the device meets JESD22-B102 for solderability. The SMB10J10AHM3/I reel configuration supports high-volume automotive manufacturing with full traceability and humidity-sensitive packaging per MSL Level 1.
