Product details
Overview
SMA5J9.0HE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR), 15.4 V clamping voltage (VC) at 5.0 A peak pulse current, and 500 W peak pulse power rating - deployed in automotive ECUs, industrial sensor interfaces, and DC power input stages.
For engineers reviewing the SMA5J9.0HE3/61 datasheet, SMA5J9.0HE3/61 pinout, SMA5J9.0HE3/61 application, or SMA5J9.0HE3/61 equivalent, key selection criteria include AEC-Q101 qualification, 150 °C maximum junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, responding to transients within picoseconds via avalanche breakdown. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable clamping performance under repetitive 10/1000 μs surges up to 500 W.
Thermal design relies on RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), requiring minimum pad layout per Vishay spec for rated IPPM derating above 25 °C. The HE3 suffix confirms AEC-Q101 qualification and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 10.0 V / 11.1 V at 1.0 mA - Ensures reliable turn-on margin above VWM without premature clamping |
| VC @ IPPM | 15.4 V at 5.0 A - Limits protected circuit voltage during worst-case 10/1000 μs surge |
| PPPM | 500 W - Sustains high-energy transients common in automotive load-dump and inductive switching |
| IR @ VWM | ≤1.0 μA - Minimizes standby power loss and avoids false triggering in low-current sensor rails |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and enclosed industrial enclosures |
| Package | DO-214AC (SMA) - Standardized surface-mount footprint compatible with IPC-7351B land patterns |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with matte tin-plated leads, cathode band marking on anode-side terminal; meets UL 94 V-0, MSL Level 1 (260 °C reflow peak), and J-STD-002/JESD22-B102 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction | Connected to ground or low-impedance return path in unidirectional clamp configuration |
| Cathode (banded end) | Current exit during reverse-biased clamping | Connected to protected line (e.g., 12 V rail or CAN-H); defines polarity-sensitive placement |
Key Features
| Feature | Design Value |
|---|---|

| Glass-passivated junction | Ensures long-term parameter stability and low leakage drift over 15-year service life in harsh environments |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
| MSL Level 1 rating | Enables single-reflow assembly without baking; supports high-volume SMT production with standard reflow profiles |
| RoHS-compliant HE3 suffix | Meets JESD201 Class 2 whisker resistance and EU RoHS Directive 2011/65/EU without exemptions |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V supply inputs of body control modules against load-dump transients (ISO 16750-2) and alternator ripple.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J9.0A-E3/61 | Commercial-grade variant; lacks AEC-Q101 qualification and JESD201 Class 2 whisker resistance | Suitable for non-automotive industrial or consumer applications where qualification is not mandated | Select when cost sensitivity outweighs automotive reliability requirements |
| SMC5J9.0AHE3/61 | Same electrical specs but in larger DO-214AB (SMC) package; higher thermal mass (RθJA = 35 °C/W) | Better suited for high-repetition-rate surges or elevated ambient temperatures (>85 °C) | Choose when PCB layout allows larger footprint and thermal performance exceeds SMA5J9.0HE3/61 limits |
Compared with SMA5J9.0A-E3/61, the SMA5J9.0HE3/61 adds automotive qualification and enhanced whisker resistance without altering clamping behavior; versus SMC5J9.0AHE3/61, it trades thermal robustness for space-constrained layouts while retaining identical electrical protection thresholds.

FAQ
What is the clamping voltage of the SMA5J9.0HE3/61 under a 10/1000 µs surge?
The SMA5J9.0HE3/61 clamps to a maximum of 15.4 V at 5.0 A peak pulse current under a standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects worst-case voltage seen by downstream circuitry during surge events - critical for ensuring protected ICs remain within absolute maximum ratings.
Is the SMA5J9.0HE3/61 suitable for automotive applications?
Yes, the SMA5J9.0HE3/61 is AEC-Q101 qualified and specifically designed for automotive use. Its HE3 suffix denotes compliance with AEC-Q101 stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for engine control units, infotainment power supplies, and ADAS sensor interfaces.
What does the "HE3" suffix mean in SMA5J9.0HE3/61?
The "HE3" suffix in SMA5J9.0HE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. Unlike the "E3" commercial variant, HE3 ensures enhanced reliability for automotive and industrial applications where long-term solder joint integrity and environmental stress resistance are mandatory.
How does the SMA5J9.0HE3/61 differ from the SMA5J9.0A-E3/61?
The SMA5J9.0HE3/61 differs from SMA5J9.0A-E3/61 primarily in qualification level: HE3 carries AEC-Q101 certification and JESD201 Class 2 whisker resistance, whereas E3 is commercial-grade only. Electrical parameters (VWM, VBR, VC, PPPM) are identical; both use DO-214AC packaging and share the same 1800-piece 7" tape-and-reel delivery format.
What is the maximum junction temperature rating for the SMA5J9.0HE3/61?
The SMA5J9.0HE3/61 has a maximum junction temperature (TJ) rating of +150 °C. This enables reliable operation in under-hood automotive environments and sealed industrial enclosures, provided thermal design follows Vishay's recommended 0.2" × 0.2" copper pad layout to maintain RθJA ≤ 80 °C/W.
