Product details
Overview
SMB10J17AHM3/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 17 V stand-off voltage (VWM), 1000 W peak pulse power (10/1000 µs), clamping voltage of 27.6 V at 36.2 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMB10J17AHM3/I datasheet, SMB10J17AHM3/I pinout, SMB10J17AHM3/I application, or SMB10J17AHM3/I equivalent, key selection criteria include clamping performance under 10/1000 µs transients, thermal resistance (RθJA = 72 °C/W), AEC-Q101 compliance status, and halogen-free RoHS-compliant construction per suffix HM3.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional polarity and cathode-band marking align with standard PCB layout conventions for DC-biased protection paths.
The device operates across -55 °C to +150 °C junction temperature range and is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine). Mounting on 5.0 mm × 5.0 mm copper pads ensures thermal derating compliance per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected line |
| VBR min/max | 18.9 V / 20.9 V at 1.0 mA - breakdown voltage tolerance band used to verify conformance during production test |
| VC @ IPPM | 27.6 V at 36.2 A - clamping voltage under 10/1000 µs surge; determines maximum stress imposed on downstream IC or MOSFET |
| PPPM | 1000 W - peak pulse power handling capability; defines energy absorption capacity for standardized surge waveforms |
| IFSM | 100 A - single half-sine surge current rating (8.3 ms); critical for protecting against motor or relay coil turn-off spikes |
| TJ max | +150 °C - maximum junction temperature; sets thermal design limits for board-level power dissipation and pad sizing |
| RθJA | 72 °C/W - junction-to-ambient thermal resistance; used to calculate temperature rise under repetitive surge conditions |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge conduction | Connected to lower-potential side (e.g., GND or return path) in unidirectional configuration |
| Cathode | Reverse-biased terminal during normal operation; clamps when VAK exceeds VBR | Connected to protected line (e.g., 12 V rail or sensor input); color band identifies this end |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability under thermal cycling and vibration |
| Halogen-free, RoHS-compliant (HM3 suffix) | Meets environmental compliance requirements for Tier-1 automotive suppliers and industrial equipment exported to EU/Asia markets |
| MSL Level 1 (260 °C peak reflow) | Enables compatibility with standard lead-free SMT assembly processes without moisture sensitivity concerns or baking requirements |
| Glass passivated junction | Provides stable leakage current (<1.0 µA at VWM) and consistent clamping behavior over lifetime and temperature extremes |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin for sensitive receivers |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J17AHE3/I | Same electrical specs, but RoHS-compliant commercial grade (E3) without halogen-free certification | Lacks halogen-free compliance; suitable for non-automotive industrial use where HM3 is not mandated | Select when AEC-Q101 is unnecessary and cost optimization is prioritized over material restrictions |
| SMBJ17A-M3/5B | Same SMB package and 17 V VWM, but rated for 600 W PPPM (vs. 1000 W) and 24.4 V clamping at 24.4 A | Lower surge capacity; insufficient for ISO 16750-2 load dump or high-energy motor snubbing | Use only in low-energy signal-line protection where 600 W suffices and footprint compatibility is required |
Compared with SMB10J17AHM3/I, SMB10J17AHE3/I offers identical surge performance but lacks halogen-free assurance, while SMBJ17A-M3/5B trades 40 % lower peak power for broader distributor availability-neither is pin-compatible drop-in replacement due to differing surge ratings and qualification scope.

FAQ
What is the clamping voltage of SMB10J17AHM3/I under a 10/1000 µs surge?
The SMB10J17AHM3/I clamps to a maximum of 27.6 V when subjected to its rated peak pulse current of 36.2 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMB10J17AHM3/I qualified for automotive applications?
Yes, SMB10J17AHM3/I is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88422, Revision 09-Jan-2024). The HM3 suffix denotes halogen-free, RoHS-compliant construction validated for automotive use, including under-hood and ADAS subsystems.
What does the "HM3" suffix mean in SMB10J17AHM3/I?
The "HM3" suffix in SMB10J17AHM3/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It replaces legacy "HE3" (RoHS + AEC-Q101) by adding halogen-free material compliance per IEC 61249-2-21, required by many Tier-1 automotive OEMs.
Can SMB10J17AHM3/I be used in bidirectional configurations?
No, SMB10J17AHM3/I is unidirectional only. Its cathode band marking and electrical specifications (e.g., VBR, VC) apply solely to reverse-biased operation. For bidirectional protection, Vishay offers the SMB8J17CA series, which has distinct marking codes and lower peak pulse power (800 W).
What is the maximum operating temperature for SMB10J17AHM3/I?
The SMB10J17AHM3/I has a maximum junction temperature (TJ) of +150 °C and an operating storage temperature range of -55 °C to +150 °C. This rating supports use in under-hood automotive environments and industrial enclosures with elevated ambient temperatures.
