Product details
Overview
SMA5J9.0AHE3/61 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 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR), 15.4 V clamping voltage at 5.0 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J9.0AHE3/61 datasheet, SMA5J9.0AHE3/61 pinout, SMA5J9.0AHE3/61 application, or SMA5J9.0AHE3/61 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HE3 suffix), RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (10.0–11.1 V), limiting transient-induced overvoltage to ≤15.4 V at 5.0 A. Its glass-passivated junction ensures stable leakage (<1.0 μA at 9.0 V) and fast response time (<1.0 ns), critical for protecting sensitive inputs against ESD and inductive switching spikes.
Thermally, it exhibits RθJA = 80 °C/W and RθJL = 25 °C/W, enabling reliable operation up to 150 °C junction temperature. The HE3 suffix confirms AEC-Q101 qualification, RoHS compliance, and JESD201 Class 2 whisker resistance - making it suitable for automotive front-end power rails and industrial control I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias range for protected circuitry. |
| VBR min/max | 10.0 V / 11.1 V - measured at 1.0 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 15.4 V at 5.0 A - clamped voltage during 10/1000 μs surge; determines worst-case overvoltage seen by downstream components. |
| PPPM | 500 W - peak pulse power handling per 10/1000 μs waveform; supports robust protection against lightning and load dump transients. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage at rated stand-off voltage; avoids parasitic loading on low-power sensor or reference circuits. |
| TJ max | +150 °C - maximum junction temperature; enables use in under-hood automotive environments and enclosed industrial enclosures. |
| Package | SMA (DO-214AC) - surface-mount package with 5.28 mm × 4.50 mm footprint and 2.29 mm height; compatible with standard reflow profiles (MSL Level 1, 260 °C peak). |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads; cathode indicated by band at one end; terminals solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point (unidirectional) | Connected to ground or low-impedance return path; forms clamping loop with cathode during surge events. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line (e.g., 12 V rail); avalanche conduction initiates here when VLINE > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units and body electronics with extended temperature and life-cycle reliability. |
| Glass passivated junction | Ensures stable electrical parameters over time and humidity exposure; eliminates risk of junction corrosion in harsh environments. |

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 | Same electrical specs, but commercial-grade (non-AEC-Q101); no automotive qualification; identical package and marking. | Approved for industrial/commercial use only; not validated for automotive temperature cycling or lifetime stress testing. | Select SMA5J9.0AHE3/61 when AEC-Q101 compliance is required; choose SMA5J9.0A-E3/61 for cost-sensitive non-automotive designs. |
| SMA6J9.0AHE3/61 | Higher PPPM (600 W vs. 500 W); same VWM/VBR/VC; larger thermal mass due to SMA package variant (DO-214AC vs. DO-214AB). | Better suited for higher-energy transients (e.g., ISO 7637-2 Pulse 5a); requires verification of PCB pad layout compatibility. | Use SMA6J9.0AHE3/61 where surge energy exceeds 500 W margin; confirm mechanical fit and thermal derating per layout. |

FAQ
What is the clamping voltage of the SMA5J9.0AHE3/61 and how is it measured?
The SMA5J9.0AHE3/61 has a maximum clamping voltage (VC) of 15.4 V, measured at a peak pulse current (IPPM) of 5.0 A using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the highest voltage the device allows across its terminals during a standardized surge event, ensuring downstream components see no more than 15.4 V. The SMA5J9.0AHE3/61 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is the SMA5J9.0AHE3/61 suitable for automotive applications?
Yes, the SMA5J9.0AHE3/61 is AEC-Q101 qualified, RoHS-compliant, and tested per JESD201 Class 2 for whisker resistance - confirming suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. Its 150 °C maximum junction temperature and stable leakage (<1.0 μA at 9.0 V) meet stringent automotive reliability requirements. The SMA5J9.0AHE3/61 is explicitly designated for automotive use via the "HE3" suffix.
What does the "HE3" suffix mean in SMA5J9.0AHE3/61?
The "HE3" suffix in SMA5J9.0AHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It distinguishes the part from commercial variants (e.g., "E3") and halogen-free versions (e.g., "HM3"). The "HE3" designation confirms the SMA5J9.0AHE3/61 meets automotive-grade reliability standards for temperature cycling, humidity resistance, and long-term stability - essential for under-hood and chassis-mounted electronics.
How does the SMA5J9.0AHE3/61 compare to bidirectional TVS diodes like SMA5J9.0CA?
The SMA5J9.0AHE3/61 is unidirectional and intended for DC power line protection where polarity is fixed (e.g., 12 V input rails), offering forward conduction capability and lower leakage. In contrast, SMA5J9.0CA is bidirectional and used in AC-coupled or polarity-agnostic signal lines (e.g., USB, audio). The SMA5J9.0AHE3/61 has a cathode band marking; SMA5J9.0CA has no polarity marking. Their clamping voltages and PPPM ratings differ slightly due to internal structure - always consult the respective datasheet tables for exact values.
What is the thermal resistance of the SMA5J9.0AHE3/61 and how does it affect layout design?
The SMA5J9.0AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe operation below 150 °C junction temperature, PCB layout must provide adequate copper area and minimize thermal impedance - especially under repeated surge conditions. The SMA5J9.0AHE3/61 datasheet specifies minimum pad dimensions to achieve these Rθ values; deviating reduces power handling capability.
