Product details
Overview
SMA5J10AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to safeguard automotive ECUs, industrial sensor interfaces, and DC power rails against ESD and load dump.
For engineers reviewing the SMA5J10AHE3_A/I datasheet, SMA5J10AHE3_A/I pinout, SMA5J10AHE3_A/I application, or SMA5J10AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 10 V and rapidly transitions to low-impedance conduction above VBR (min 11.1 V) to limit transient voltages. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed for unidirectional protection only, SMA5J10AHE3_A/I exhibits VF = 3.5 V at IF = 25 A and supports IFSM = 40 A (8.3 ms half-sine), making it suitable for DC power line protection where reverse conduction must be blocked. Thermal resistance is RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), enabling effective heat dissipation in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC working range. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - precise breakdown threshold ensuring predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 29.4 A - clamped voltage level limiting downstream IC stress during 500 W surge events. |
| PPPM | 500 W (10/1000 µs) - peak surge energy handling capacity compatible with ISO 7637-2 Pulse 1/2a/5a requirements. |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and industrial enclosures without derating. |
| Polarity | Unidirectional - cathode-banded device; blocks reverse current while clamping positive transients to ground. |
| MSL Level | Level 1 (J-STD-020), 260 °C peak reflow - supports standard lead-free SMT assembly without moisture sensitivity concerns. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side terminal | Connected to protected line (e.g., battery rail or signal trace); conducts surge current toward cathode when overvoltage occurs. |
| Cathode | Ground/reference terminal | Connected to system ground or low-impedance return path; defines unidirectional clamping direction and polarity-sensitive mounting. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment power supplies. |
| Glass passivated junction | Ensures stable VBR over temperature and lifetime, minimizing parameter drift in harsh thermal cycling environments. |
| Low incremental surge resistance | Enables tighter VC-VBR margin (ΔV = 5.9 V), reducing voltage overshoot during fast-rising transients like EFT or ESD. |
| MSL Level 1 rating | Eliminates bake-out requirement prior to reflow, streamlining high-volume SMT manufacturing and reducing process risk. |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for compliance in automotive and industrial safety-critical assemblies. |
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 |
|---|---|---|---|
| SMA5J10AHM3_A/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected when halogen-free material compliance is required for end-product environmental certification. | Direct material substitution where halogen content restrictions apply (e.g., EU WEEE, Japan J-Moss). |
| SMA5J10A-E3/5A | Commercial-grade (non-AEC-Q101), same electrical parameters, packaged in 13" tape/reel (7500 pcs) with P/N-E3 suffix. | Lacks automotive qualification; suitable for consumer, computing, and non-safety-critical industrial use. | Cost-optimized alternative for non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMA5J10AHE3_A/I, SMA5J10AHM3_A/I offers identical surge performance with halogen-free construction, while SMA5J10A-E3/5A provides equivalent clamping and power ratings without automotive qualification - enabling trade-offs between compliance scope, material content, and cost.

FAQ
What is the clamping voltage of SMA5J10AHE3_A/I at its rated peak pulse current?
The SMA5J10AHE3_A/I has a maximum clamping voltage (VC) of 17.0 V when subjected to its peak pulse current (IPPM) of 29.4 A using a 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream circuitry. The SMA5J10AHE3_A/I maintains this clamping performance across its specified operating temperature range.
Is SMA5J10AHE3_A/I qualified for automotive applications?
Yes, SMA5J10AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88875. This qualification validates its reliability under automotive temperature cycling, humidity, mechanical shock, and surge stress conditions. The SMA5J10AHE3_A/I is routinely deployed in engine control units, ADAS camera modules, and body electronics where automotive-grade assurance is mandatory.
What is the meaning of the "_A/I" suffix in SMA5J10AHE3_A/I?
The "_A/I" suffix in SMA5J10AHE3_A/I denotes the revision code ("A") and packaging format ("I" = 13-inch tape and reel, 7500 pieces per reel). This matches Vishay's ordering convention shown in the "Ordering Information" section of datasheet 88875. The SMA5J10AHE3_A/I is supplied in moisture-sensitive packaging compliant with MSL Level 1 and rated for peak reflow of 260 °C.
Can SMA5J10AHE3_A/I be used in bidirectional protection circuits?
No, SMA5J10AHE3_A/I is a unidirectional TVS diode, as indicated by its "A" suffix (vs. "CA" for bidirectional variants). It conducts only in reverse bias above VBR and blocks forward current beyond VF ≈ 3.5 V at 25 A. For bidirectional protection, engineers must select an SMA5J10CA variant - the SMA5J10AHE3_A/I will not suppress negative-going transients on AC or differential lines.
What is the thermal resistance of SMA5J10AHE3_A/I from junction to ambient?
The typical thermal resistance from junction to ambient (RθJA) for SMA5J10AHE3_A/I is 80 °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 of datasheet 88875. This value assumes standard JEDEC test board conditions and informs thermal design margins for sustained surge duty cycles or elevated ambient temperatures.
