Product details
Overview
SMA5J6.5HE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-214AC (SMA) package, designed for high-energy surge protection with 500 W peak pulse power, 6.5 V stand-off voltage, and 11.2 V clamping voltage at 44.6 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and MOSFET gates against inductive switching transients.
For engineers reviewing the SMA5J6.5HE3/61 datasheet, SMA5J6.5HE3/61 pinout, SMA5J6.5HE3/61 application, or SMA5J6.5HE3/61 equivalent, key selection criteria include unidirectional polarity, 6.5 V VWM, 7.22–7.98 V VBR range, 150 °C max junction temperature, and RoHS-compliant AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient overvoltages. Its low incremental surge resistance and stable clamping performance under 10/1000 μs waveform ensure predictable protection behavior during repetitive or single-event surges.
The SMA5J6.5HE3/61 is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 80 °C/W junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads, and maintains leakage <500 μA at VWM across -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum reverse working voltage before conduction begins; defines safe operating margin for protected circuit. |
| VBR min/max | 7.22 V / 7.98 V - Breakdown voltage range at 10 mA test current; ensures consistent avalanche initiation across production lot. |
| VC @ IPPM | 11.2 V - Clamping voltage at 44.6 A peak pulse current; limits maximum voltage seen by downstream IC or MOSFET. |
| PPPM | 500 W - Peak pulse power handling capability with 10/1000 μs waveform; determines survivability against ISO 7637-2 Pulse 1/2a/5a events. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| Package | DO-214AC (SMA) - Surface-mount package with 5.28 mm × 4.50 mm footprint and 2.29 mm height; compatible with automated pick-and-place and reflow. |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with matte tin-plated leads, cathode band marking on one end, compliant with UL 94 V-0 flammability rating and J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; carries surge current to reference plane. |
| Cathode (banded end) | Avalanche breakdown terminal | Connected to protected line (e.g., sensor output); initiates clamping when reverse voltage exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| Glass passivated junction | Ensures long-term stability of breakdown characteristics and resistance to humidity-induced parameter drift. |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without moisture sensitivity concerns; eliminates pre-bake requirement. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., load dump), improving protection margin for 3.3 V/5 V logic. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5A-E3/61 | Same electrical specs but commercial-grade (non-AEC-Q101); identical DO-214AC package and pinout. | Not qualified for automotive use; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive qualification requirement and thermal/environmental conditions remain within commercial limits. |
| SMC5J6.5AHE3/61 | Higher 1500 W PPPM, same VWM/VC, larger DO-214AB (SMC) package (7.11 mm × 6.22 mm). | Requires PCB layout change; suited for systems needing higher surge margin (e.g., 24 V industrial PLC I/O). | Choose when system-level surge testing exceeds 500 W requirements and board space allows larger footprint. |
Compared with SMA5J6.5A-E3/61, the SMA5J6.5HE3/61 adds AEC-Q101 qualification for automotive deployment; compared with SMC5J6.5AHE3/61, it trades surge capacity for smaller DO-214AC footprint-ideal for space-constrained automotive sensor modules.

FAQ
What is the polarity configuration of the SMA5J6.5HE3/61?
The SMA5J6.5HE3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the package body, and it conducts only when the cathode is at a higher potential than the anode-making it suitable for DC line protection where polarity is fixed, such as 5 V or 12 V supply rails.
Does the SMA5J6.5HE3/61 meet automotive qualification standards?
Yes, the SMA5J6.5HE3/61 is AEC-Q101 qualified, as confirmed by Vishay's documentation and suffix "HE3" designation. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its suitability for under-hood and chassis-mounted automotive electronics.
What is the clamping voltage of the SMA5J6.5HE3/61 at its rated peak pulse current?
The SMA5J6.5HE3/61 has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPPM) of 44.6 A, measured under the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range.
Can the SMA5J6.5HE3/61 be used in bi-directional applications?
No, the SMA5J6.5HE3/61 is strictly unidirectional. For bi-directional protection, Vishay offers the SMA5J6.5CA variant (with "CA" suffix), which lacks polarity marking and provides symmetrical clamping in both directions-required for AC-coupled or floating signal lines.
What is the thermal resistance of the SMA5J6.5HE3/61 in standard mounting conditions?
The SMA5J6.5HE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC 51-2 PCB layout and is critical for calculating junction temperature rise during sustained surge events.
